Texte intégralRésumé :
Abstract. The data sets described in this paper provide a basis for developing and testing new methods for monitoring and modelling urban pluvial flash floods. Pluvial flash floods are a growing hazard to property and inhabitants' well-being in urban areas. However, the lack of appropriate data collection methods is often cited as an impediment for reliable flood modelling, thereby hindering the improvement of flood risk mapping and early warning systems. The potential of surveillance infrastructure and social media is starting to draw attention for this purpose. In the floodX project, 22 controlled urban flash floods were generated in a flood response training facility and monitored with state-of-the-art sensors as well as standard surveillance cameras. With these data, it is possible to explore the use of video data and computer vision for urban flood monitoring and modelling. The floodX project stands out as the largest documented flood experiment of its kind, providing both conventional measurements and video data in parallel and at high temporal resolution. The data set used in this paper is available at https://doi.org/10.5281/zenodo.830513.

Texte intégralRésumé :
<p><strong>Abstract.</strong> In this paper, we review state of the art 3D visualization technologies for floods and we focus on the Netherlands since it has a long history of dealing with floods and developing information technology solutions to prevent and predict them. We discuss the most recent advances in using 3D city models for modelling floods and discuss future directions. We argue that 3D city models provide a more realistic interpretation and assessment of floods e.g. information about the height of the water level and the number of floors that will be flooded. We present our framework to dynamically visualize floods in 3D using the Cesium 3D webglobe. An open platform using 3D city models for interactive visualization of different flood simulations can serve as a hub to involve all relevant parties such as water experts, policy developers, decision makers, and general public. We created a 3D terrain model with buildings of a study area in the Netherlands in CityJSON format. We implemented a software prototypes for converting 3D city models from CityJSON to Cesium specific glTF format for rendering over Cesium. We propose using CZML (Cesium Language) to represent time dynamic properties, water levels in our case. The developed framework which uses only open data and open-source software can be supportive in real applications such as planning for a city or municipal corporation, or for decision making.</p>

Case study : 2006 Danube extreme flood in Romania ». Journal of Hydrology and Hydromechanics 64, no 4 (1 décembre 2016) : 329–36. http://dx.doi.org/10.1515/johh-2016-0040.
Texte intégralRésumé :
Abstract Flooding remains the most widely distributed natural hazard in Europe, leading to significant economic and social impact. Earth observation data is presently capable of making fundamental contributions towards reducing the detrimental effects of extreme floods. Technological advance makes development of online services able to process high volumes of satellite data without the need of dedicated desktop software licenses possible. The main objective of the case study is to present and evaluate a methodology for mapping of flooded areas based on MODIS satellite images derived indices and using state-of-the-art geospatial web services. The methodology and the developed platform were tested with data for the historical flood event that affected the Danube floodplain in 2006 in Romania. The results proved that, despite the relative coarse resolution, MODIS data is very useful for mapping the development flooded area in large plain floods. Moreover it was shown, that the possibility to adapt and combine the existing global algorithms for flood detection to fit the local conditions is extremely important to obtain accurate results.

Texte intégralRésumé :
The assessment and mapping of riverine flood hazards and risks is recognized by many countries as an important tool for characterizing floods and developing flood management plans. Often, however, these management plans give attention primarily to open-water floods, with ice-jam floods being mostly an afterthought once these plans have been drafted. In some Nordic regions, ice-jam floods can be more severe than open-water floods, with floodwater levels of ice-jam floods often exceeding levels of open-water floods for the same return periods. Hence, it is imperative that flooding due to river ice processes be considered in flood management plans. This also pertains to European member states who are required to submit renewed flood management plans every six years to the European governance authorities. On 19 and 20 October 2022, a workshop entitled “Assessing and mitigating ice-jam flood hazard and risk” was hosted in Poznań, Poland to explore the necessity of incorporating ice-jam flood hazard and risk assessments in the European Union’s Flood Directive. The presentations given at the workshop provided a good overview of flood risk assessments in Europe and how they may change due to the climate in the future. Perspectives from Norway, Sweden, Finland, Germany, and Poland were presented. Mitigation measures, particularly the artificial breakage of river ice covers and ice-jam flood forecasting, were shared. Advances in ice processes were also presented at the workshop, including state-of-the-art developments in tracking ice-floe velocities using particle tracking velocimetry, characterizing hanging dam ice, designing new ice-control structures, detecting, and monitoring river ice covers using composite imagery from both radar and optical satellite sensors, and calculating ice-jam flood hazards using a stochastic modelling approach.

Texte intégralRésumé :
Abstract. Fluvial floods are destructive hazards that affect millions of people worldwide each year. Forecasting flood events and their potential impacts therefore is crucial for disaster preparation and mitigation. Modeling flood inundation based on extreme value analysis of river discharges is an alternative to physical models of flood dynamics, which are computationally expensive. We present the implementation of a globally applicable, open-source fluvial flood model within a state-of-the-art risk modeling framework. It uses openly available data to rapidly compute flood inundation footprints of historic and forecasted events for the estimation of associated impacts. For the example of Pakistan, we use this flood model to compute flood depths and extents and employ it to estimate population displacement due to floods. Comparing flood extents to satellite data reveals that incorporating estimated flood protection standards does not necessarily improve the flood footprint computed by the model. We further show that, after calibrating the vulnerability of the impact model to a single event, the estimated displacement caused by past floods is in good agreement with disaster reports. Finally, we demonstrate that this calibrated model is suited for probabilistic impact-based forecasting.

Llasat, María Carmen. « Floods evolution in the Mediterranean region in a context of climate and environmental change ». Cuadernos de Investigación Geográfica 47, no 1 (17 mai 2021) : 13–32. http://dx.doi.org/10.18172/cig.4897.
Texte intégralRésumé :
Floods are the most important risk in the Mediterranean region, both due to their frequency and impact. Studies of historical floods show flood-rich periods that could be associated with climate causes, but there is also a certain growing trend as a result of changes in land use and increased vulnerability. If climate scenarios point to an increase in the torrentiality of precipitation, with longer dry periods and more intense rainfall, there is still a high level of uncertainty in their impact in floods. This paper addresses this issue, also considering the complex role of changes to hazards, vulnerability, exposure and capacity. It presents a synthesis of the state of the art, with particular incidence in the first results of MedECC and the most recent bibliography on floods trend. Conclusions show that floods in this region are mainly consequence of flash-flood events. A common positive trend of flash floods in the past probably due to land use changes and the occupation of flood-prone areas has been found (high confidence). The increase of convective precipitation could also justify this positive trend in the most recent period, in some regions (low confidence). Vulnerabilities to water related hazards are expected to be influenced by the future socio-economic conditions at the regional scale (medium confidence). Although expected changes in flood risks are not univocal, nor evenly distributed, flood impacts will increase in the entire Mediterranean region, mainly as a consequence of global changes in the catchments (land use, vulnerability, exposure), joined in the Northern part of the basin to the increase of heavy rainfalls (medium confidence).

Texte intégralRésumé :
Abstract. Current climate modelling frameworks present significant uncertainties when it comes to quantifying flood quantiles in the context of climate change, calling for new information and strategies in hazard assessments. Here, state-of-the-art methods on hydraulic and statistical modelling are applied to historical and contemporaneous flood records to evaluate flood hazards beyond natural climate cycles. A comprehensive flood record of the Duero River in Zamora (Spain) was compiled from documentary sources, early water-level readings and continuous gauge records spanning the last 500 years. Documentary evidence of flood events includes minute books (municipal and ecclesiastic), narrative descriptions, epigraphic marks, newspapers and technical reports. We identified 69 flood events over the period 1250 to 1871, of which 15 were classified as catastrophic floods, 16 as extraordinary floods and 38 as ordinary floods. Subsequently, a two-dimensional hydraulic model was implemented to relate flood stages (flood marks and inundated areas) to discharges. The historical flood records show the largest floods over the last 500 years occurred in 1860 (3450 m3 s−1), 1597 (3200 m3 s−1) and 1739 (2700 m3 s−1). Moreover, at least 24 floods exceeded the perception threshold of 1900 m3 s−1 during the period (1500–1871). Annual maximum flood records were completed with gauged water-level readings (pre-instrumental dataset, PRE: 1872–1919) and systematic gauge records (systematic dataset, SYS: 1920–2018). The flood frequency analyses were based on (1) the expected moments algorithm (EMA) and (2) the maximum likelihood estimator (MLE) method, using five datasets with different temporal frameworks (historic dataset, HISTO: 1511–2018; PRE–SYS: 1872–2018; full systematic record, ALLSYS: 1920–2018; SYS1: 1920–1969; and SYS2: 1970–2018). The most consistent results were obtained using the HISTO dataset, even for high quantiles (0.001 % annual exceedance probability, AEP). PRE–SYS was robust for the 1 % AEP flood with increasing uncertainty in the 0.2 % AEP or 500-year flood, and ALLSYS results were uncertain in the 1 % and 0.2 % AEP floods. Since the 1970s, the frequency of extraordinary floods (>1900 m3 s−1) declined, although floods on the range of the historical perception threshold occurred in 2001 (2075 m3 s−1) and 2013 (1654 m3 s−1). Even if the future remains uncertain, this bottom-up approach addresses flood hazards under climate variability, providing real and certain flood discharges. Our results can provide a guide on low-regret adaptation decisions and improve public perception of extreme flooding.

Texte intégralRésumé :
Over the past 10 years, urban floods have increased in frequency because of extreme rainfall events and urbanization development. To reduce the losses caused by floods, various urban flood models have been developed to realize urban flood early warning. Using CiteSpace software’s co-citation analysis, this paper reviews the characteristics of different types of urban flood models and summarizes state-of-the-art technologies for flood model development. Artificial intelligence (AI) technology provides an innovative approach to the construction of data-driven models; nevertheless, developing an AI model coupled with flooding processes represents a worthwhile challenge. Big data (such as remote sensing, crowdsourcing geographic, and Internet of Things data), as well as spatial data management and analysis methods, provide critical data and data processing support for model construction, evaluation, and application. The further development of these models and technologies is expected to improve the accuracy and efficiency of urban flood simulations and provide support for the construction of a multi-scale distributed smart flood simulation system.

Texte intégralRésumé :
Floods are devastating phenomena that occur almost all around the world and are responsible for significant losses, in terms of both human lives and economic damages. When floods occur, one of the challenges that emergency response agencies face is the identification of the flooded area so that access points and safe routes can be determined quickly. This study presents a flood detection methodology that combines transfer learning with vision transformers and satellite images from open datasets. Transformers are powerful models that have been successfully applied in Natural Language Processing (NLP). A variation of this model is the vision transformer (ViT), which can be applied to image classification tasks. The methodology is applied and evaluated for two types of satellite images: Synthetic Aperture Radar (SAR) images from Sentinel-1 and Multispectral Instrument (MSI) images from Sentinel-2. By using a pre-trained vision transformer and transfer learning, the model is fine-tuned on these two datasets to train the models to determine whether the images contain floods. It is found that the proposed methodology achieves an accuracy of 84.84% on the Sentinel-1 dataset and 83.14% on the Sentinel-2 dataset, revealing its insensitivity to the image type and applicability to a wide range of available visual data for flood detection. Moreover, this study shows that the proposed approach outperforms state-of-the-art CNN models by up to 15% on the SAR images and 9% on the MSI images. Overall, it is shown that the combination of transfer learning, vision transformers, and satellite images is a promising tool for flood risk management experts and emergency response agencies.

Texte intégralRésumé :
Floods are threats seriously affecting people’s lives and property globally. Risk analysis such as flood susceptibility assessment is one of the critical approaches to mitigate flood impacts. However, the inadequate field survey and lack of data might hinder the mapping of flood susceptibility. The emergence of user-generated content (UGC) in the era of big data provides new opportunities for flood risk management. This research proposed a flood susceptibility assessment model using UGC as a potential data source and conducted empirical research in Ji’an County in China to make up for the lack of ground survey data in mountainous-hilly areas. This article used python crawlers to obtain the geographic location of the floods in Ji’an City from 2016 to 2019 from social media, and the state-of-the-art MaxEnt algorithm was adopted to obtain the flood occurrence map. The map was verified by the flood data crawled from reliable official media, which achieved an average AUC of 0.857% and an overall accuracy of 93.1%. Several novel indicators were used to evaluate the importance of conditioning factors from different perspectives. Land use, slope, and distance from the river were found to contribute most to the occurrence of floods. Our findings have shown that the proposed historical UG C-based model is practical and has good flood-risk-mapping performance. The importance of the conditioning factors to the occurrence of floods can also be ranked. The reports from stakeholders are a great supplement to the insufficient field survey data and tend to be valuable resources for flood disaster preparation and mitigation in the future. Finally, the limitations and future development directions of UGC as a data source for flood risk assessment are discussed.

Texte intégralRésumé :
This dissertation explores the understanding of origins in late medieval and Renaissance Florence as represented in art and in wider fields of literary and historiographic discourse. Its particular focus is a myth associating the foundation of Tuscany with Noah, which was promoted in a volume of forged texts published by Annius of Viterbo in 1498. Rather than focusing on Annius or his scholarly reception as other writers have done, the thesis attempts to set the myths that he publicised in the context of other stories about origins that circulated in Renaissance Florence. The central part of the thesis consists of three chapters each of which takes its lead from a particular science of origins: etymology, genealogy and archaeology. The topics discussed in them, however, range beyond the strict confines of these disciplines to include such themes as: the shifting narratives of the foundation of Florence; family history as recorded in Florentine ricordanze; portraits as an expression of patrilineal ideology; and the legend of the Florentine Baptistery as a former temple of Mars together with its influence on Renaissance architecture. A recurring theme in these chapters is that of the origin narrative as a myth that serves to justify present-day arrangements or identities. The final chapter develops the theme of origins to encompass ideas of historical recurrence and renewal. In a discussion that draws heavily on the writings of Machiavelli I attempt to show that Florentine cyclical conceptions of history relied on a model of returning to the origin. The chapter closes with a discussion of Renaissance artists who were either perceived as the re-embodiment of an artistic ancestor, a 'new Giotto' for example, or who actively strove to attain such a status. Finally, the conclusion attempts to draw connections between a number of the narratives discussed earlier in the thesis on the basis of a shared fantasy of autonomous male creativity

Texte intégralRésumé :
The diploma thesis deals with the possibilities of applying weather derivatives and catastrophe bonds as alternative risk transfer products, which enable to cope with natural disaster risk in the Czech Republic. The author highlights an obvious increase in occurrence and intensity of extreme climate events resulting into devastating floods. Total costs caused by floods in August 2002, which hadn't been known so far, had important impact on the Czech insurance market. The situation is in many aspects similar to circumstances, which led to the birth of ART products abroad. If the recent tendencies continue, Czech insurers will have to find new ways of dealing with these risks beside the traditional commercial insurance. In accordance with conclusions of this thesis, applying of catastrophe bonds isn't supposed in the future. However, the weather derivatives seem to be an alternative with great potential.

Rossman, Edwin J. (Edwin John). « Individual Resources, Social Environment, and Flood Victimization ». Thesis, University of North Texas, 1990. https://digital.library.unt.edu/ark:/67531/metadc330855/.
Texte intégralRésumé :
The study is a contextual analysis of flood victimization. Victimization is defined as the social, psychological, and physiological aftermath experienced by victims of a disaster. Disaster researchers concentrate on the victims' characteristics to explain the varying degrees of their victimization, providing only ambiguous results. Theorists such as Kreps, Wildavsky, and Douglas contend that the outcomes of disasters are contingent upon social structure. This analysis treats victimization as one such outcome. The condition and behavior of individuals can be explained by the presence of disaster and the conditions of social organization. A model explains victimization based on individual's attributes (individual resources), his social environment, and the disaster characteristics. This study uses the 1984 Mingo Creek Flood Victims Survey data to test the model. The data contain information measuring victimization. The survey data are linked with 1980 Census tract data. The tract data provide indicators of the social networks. This tract information, the contextual variables, taps the social conditions, including poverty, unemployment, geographic mobility, and family patterns. This study uses factor analysis to identify the dimensions of victimization. Regression tests the relationship between the contextual variables, the individual resource variables, the disaster characteristic variables, and victimization. The results of the analysis show that victimization is multidimensional with different types of variables being significant predictors for each dimension of victimization, one variable indicating the intensity of the disaster, the dollar value of damage victims experienced, is found to be a significant predictor of the psychological, physiological, and social disruption aspects of victimization. Variables measuring the family and unemployment patterns in the victims' census tract are significant predictors of the psychological and social disruption aspect of victimization. The findings provide general support for the proposed model of victimization. However, victimization is multidimensional with each dimension having a unique set of predictors. Based on the findings, this study suggests that future research focus on measurement and conceptualization of the characteristics of disasters and the victims' social environment.

A escrita desta dissertação teve como intuito discorrer sobre as ações do projeto Lastro – Intercâmbios Livres em Arte, entendendo-o como rede de contatos e plataforma de ação para projetos colaborativos. Uma proposta que visa conexões no campo da arte e cultura no contexto América Latina, porém com reverberações além-territórios. Como rede opera em diferentes frentes de trabalho e pensamento, tendo a mobilidade contemporânea como foco de estudo. Esta pesquisa propôs uma ramificação do pensamento sobre mobilidade em formato de cadernos de viagens, aprofundando pontos de vista e abordagens diferenciadas acerca do deslocamento e como este é entendido por artistas, transformando-se em poética. Quatro cadernos que se transmutarão em pequenas publicações via coleção de livros Lastro. Tal trânsito tem como objetivo fomentar projetos editoriais experimentais que atuem como dispositivo questionador e aglutinador. Além disso, tal projeto inaugura o selo editorial Lastro, o que faz nascer mais uma atividade da rede. A realização dessa pesquisa vem auxiliar uma maior compreensão conceitual do Lastro e sua potência política enquanto proposta curatorial rizomática.
The core aim in the writing of this abstract was to discourse on the project named Lastro - Intercâmbios Livres em Arte (ballast –free exchange art) seeing it as an action platform and a network for cooperative projects. A project that seeks the connections of artistic and cultural fields within the Latin-America context, though resounding beyond its limits. As a network it acts in various types of work fronts and thoughts, having a contemporary movability as its study focus. That research has proposed a branching of the thoughts on movability in the shape of travel diaries, deepening points of views and the differentiated approaches regarding movement and how it is understood by artists by shaping it into poetic. Four diaries that will take the format of small publications through the Lastro book collection. The goal of such movement is to promote the experimental publishing projects that may act as a questioning as well as unifying device. Besides, such project also inaugurates the Lastro imprint, and by doing so, we’ll be starting one more activity in its network. The execution of such research intends to enhance the conceptual comprehension of Lastro and its political potentiality as a non-hierarchical curatorship project.

Kusumastuti, Dyah Indriana. « The effects of threshold nonlinearities on the transformation of rainfall to runoff to floods in a lake dominated catchment system ». University of Western Australia. School of Environmental Systems Engineering, 2007. http://theses.library.uwa.edu.au/adt-WU2007.0124.
Texte intégralRésumé :
[Truncated abstract] Runoff generation behaviour and flooding in a lake dominated catchment are nonlinear, threshold-driven processes that result from the interactions between climate and various catchment characteristics. A complicating feature of the rainfall to runoff transformation, which may have implications for the flood frequency, is that the various surface and subsurface flow pathways are dynamic, heterogeneous and highly nonlinear, consisting of distinct thresholds. To understand the impact of threshold nonlinearities on the rainfall-runoff transformation in such catchments, a systematic examination was carried out to investigate runoff generation behaviour of the catchment itself, the overflow behaviour of a lake in combination with the catchment draining into it, as well as the lake organisation within a lake chain network. Three storage based thresholds were considered: the catchment field capacity storage governing catchment subsurface stormflow, total storage capacity governing catchment surface runoff, and lake storage capacity governing lake-overflow. ... Through these investigations, this thesis has provided valuable insights into the process controls of lake-overflow events and the associated flood frequency behaviour in lake dominated catchments. In particular, the relative roles of climate, soil depth, the soil?s drainage capacity, as well as the relative geometry of the lake vis a vis the contributing catchment, in the determination of the dynamic characteristics of lake-overflow events and associated flood frequency behaviour have been highlighted. In addition, the importance of lake organization, as expressed in terms of the average ratio of catchment area to lake area and the spatial variability of this ratio from upstream to downstream, and their impact upon connectivity and flood frequency have also been explored. The outcomes of this study highlight the importance of thresholds governing flood frequency, and provide insights into the complex interactions between rainfall variability and the various threshold nonlinearities in the rainfall-runoff process, which are shown to have a significant impact on the resulting flood frequency curves. The improved understanding of these process controls will be useful in assisting the 1 management of the catchment-lake system in the study region, and in regions elsewhere. In particular, the outcome of this study can provide guidance towards the adoption of various management strategies for lake chain systems by illustrating the effects of potential flow interruption and retardation as ways to assist in flood prevention and mitigation, whether it is aimed at decreasing the frequency of occurrence of lake overflows, or merely decreasing the flow magnitude for a given return period.

White, Melinda. « Between Floors : The Ups and Downs of Mediated Narrative ». VCU Scholars Compass, 2012. http://scholarscompass.vcu.edu/etd/433.
Texte intégralRésumé :
“Between Floors: The Ups and Downs of Mediated Narrative” and the accompanying creative remediation project, “Between Floors: Love and Other Blood Related Diseases,” meld theory and practice of print with electronic literature and installation art. I argue that as the medium changes, the narrative is transformed. The narrative can be reconstructed and pieced together as the reader or viewer becomes increasingly involved, even embodied within the work. This embodiment is what Nathaniel Stern calls “Moving and thinking and feeling” (1) and can result in a more direct emotional experience. The form, structure, and medium (sjužet) rely on authorial intention, yet as a narrative becomes more interactive and experiential the feedback loop shifts, placing meaning, message, and construction of narrative (fabula) between media and reader/viewer. This necessarily complicates the notion of authorship, yet within an embodied space, such as the installations included in this analysis, there is a potential for greater emotional understanding between author/artist and reader/viewer. In the print story “Between Floors: Love and Other Blood Related Diseases,” the protagonist, June, visits her father in a hospital after a tragedy and ends up spending the rest of her life there. The metaphor of an elevator throughout the print, electronic, and installation versions furthers the trapped, claustrophobic feeling of the narrative as well as the ups and downs of relationships and grief. Pieces of the narrative remain recognizable through the electronic literature and installation, yet as the reader/viewer is increasingly immersed in the narrative, it becomes his or her own—a more subjective and overwhelming emotional experience. The elevator metaphor extends through the analysis—an emblem of traditional linear narratives and the narrative arc and technological immersion. The analysis explores theories of language, medium, authorship, nonlinearity, interactivity, and embodiment through existing narrative, new media, and installation theorists such as Peter Brooks, Marshall McLuhan, and Nathaniel Stern. This dissertation and to an extent, experiment, uses theory and practice to illuminate narrative using a recombination of existing theory and an original remediation in three distinct forms, to further the understanding of the nature of narratives, media, authors, and readers, while blurring boundaries between disciplines.

Herrera, Rachael. « Body, Blood, and Flood : The Ripple of Kinesics through Nature in Leonardo da Vinci's Art ». Scholarship @ Claremont, 2017. http://scholarship.claremont.edu/scripps_theses/1019.
Texte intégralRésumé :
Leonardo da Vinci's art and science have a dynamic relationship that can be used to better understand the role of the individual and the human body within his art. Leonardo believed that movements of the body were expressions of the soul. He also thought that the body was as a microcosm of the physical world. The theories, based in ancient tradition, would be challenged by his work with the human anatomy. By studying his notebooks it becomes evident that Leonardo held nature to be the highest creator of the world but as he worked to understand the human body and through extension the physical world, his ideas about nature and the divine became more incomprehensible. Leonardo's art reflects this turn of perspective as he becomes unable to define the physical world through the human body.

It breaks down transportation and communication systems, disrupts businesses and causes damage to properties, loss of stock, crops and also loss of human lives. Better understanding of the impacts resulting from floods and other natural hazards can help to reduce the damages or losses. Flood damage assessment procedures estimate the impact of flood in monetary terms to help decision makers develop new policies, programs and development plans. This study examines different techniques, procedures and underpinning philosophies that have been used in some major emergency management and insurance organizations in the world such as RAM, ANUFLOOD, and HAZUS and NHRC. From this examination the study finds that none of them are suitable for mitigation and emergency purposes in producing economic flood damage estimation at fine resolution with high accuracy. From this perspective the study develops a rigorous procedure for property level economic flood damage assessment. The assessment procedures are embedded within GIS (Geographic Information System) technology which can model and analyse the multidimensional phenomenon of flood and damage characteristics of residential buildings. The damage estimation procedures developed in this study include flood modelling, collection and organisation of building inventory data; adopting a set of stage-damage curves; and measuring damage at property level. The quality of damage estimates derived from the procedures is highly influenced by quality of input data. The study also includes the implementation of the damage assessment procedure on the study area (a segment of Kororoit Creek and its adjacent area). The study uses data from a number of sources including Melbourne Water, NEXIS, VICMAP, a quick survey and literature. The developed procedure will help many practitioners in flood loss assessment and natural hazard risk management to face the challenges they have in establishing damage estimates with high accuracy.

Texte intégralRésumé :
AbstractSustainable management of wadi flash flood (WFF) risks is desperately needed to secure development in wadi systems. Due to rapid flow generation with sudden high flood peaks, spatiotemporal variability of rainfall occurrence, and poorly sited rapid development, most Middle East and North Africa (MENA) region have no comprehensive proper protection from WFFs. In arid regions, single mitigation measures, including storage dams, recharge dams, artificial lakes and embankments, are implemented, although soft mitigation measures are not dominant, such as early warning systems. The single management strategy under climate change impacts is not adequate to reduce flash flood risks; an integrated strategy is required. The objective of the international symposium on flash floods (ISFF) project has been to develop scientific understanding of WFFs in wadi systems; monitor, model, and mitigate; issue warnings; and plan urban development by discussing and networking the strategies in the MENA region. To achieve this goal, the project defines priorities for future research challenges and potential projects for WFFs. This chapter provides a state-of-the-art scientific basis in terms of integrated flash flood management. Further, priorities are defined for the main research gaps, and the emerging research methodologies can contribute to guide the management of WFFs in such regions.

Texte intégralRésumé :
AbstractFloods are frequent hazard in Algeria. They cause severe casualties, destroy infrastructures, and impair economies. In the past decades, Algeria experienced devastating floods. The dominant type of occurring floods are flash floods, which tend to be not well documented and studied in Algeria. This chapter presents a brief introduction to the flood phenomena within the Algerian climatic and management context, based on databases, scientific publications, and local technical reports. Existing studies about floods are reviewed. It also provides an analysis of the most disastrous floods that occurred in the past decades. Of the most noteworthy flash floods, a highlight of the Bab El Oued flash flood occurring in a heavily urbanized setting and the M’zab Valley flash flood, which took place in a UNESCO World Heritage Site. The monitoring network in Algeria is presented and data availability is discussed. The implementation of the first forecasting and early warning system are also presented. Different aspects of flash floods were presented including the effect of the increase of urbanization, the influence of climate change and the adopted strategies of flood risk management. Heavy and increasing urbanization and population growth increased the flood vulnerability and this trend must be mitigated.

Texte intégralRésumé :
AbstractDroughts and floods are the main threats to the Lancang-Mekong River Basin (LMRB). Drought mainly occurs during the dry season, especially in March and April, in the LMRB. The “dry gets drier” paradigm performs well in the LMRB, specifically in the Mekong Delta. Further, flood frequency and magnitude, which are determined by heavy rain, are also increasing in the LMRB. Droughts and floods show obvious seasonal and regional characteristics in the LMRB. The LMRB is a well-known rainstorm-flood basin. Floods in the LMRB are mainly caused by heavy rain. The LMRB is dominated by regional floods, and basin-wide floods rarely occur. From upstream to downstream, the flood peak and flood volume have shown increasing trends. Meanwhile, moving further downstream, the flood season ends later. In the upstream areas, floods are mainly concentrated in the period from July to October, with the highest probability of floods occurring in August. For the downstream areas, the flood season is from August to October. Climate change is one of the major factors affecting the LMRB’s droughts and floods. Global warming is an indisputable fact. Under global warming, extreme hydrological events show a tendency to increase. Climate models have suggested a future potential for increased flood frequency, magnitude, and inundation in the LMRB by 10–140%, 5–44% and 19–43%, respectively. Although the severity and duration of droughts are also increasing, the differences in drought indicators projected by different climate models are significant. Hydropower development was another major factor affecting droughts and floods in the LMRB. Large-scale hydropower development has drastically changed streamflow characteristics since 2009, causing increased dry season flow (+150%) and decreased wet season flow (−25%), as well as reduced flood magnitude (−2.3 to −29.7%) and frequency (−8.2 to −74.1%). Large-scale reservoirs will have a profound impact on hydrological characteristics, droughts and floods, agriculture, fisheries, energy supply, and environmental protection in the LMRB. Coupling climate models and hydrological models is the main way to study the impact of climate change and reservoir operation in the LMRB. Climate change indirectly affects hydrological characteristics by affecting meteorological parameters, while reservoirs can directly change the propagation from meteorological extreme events to hydrological extreme events by releasing/storing water in different situations. Hydrological models are the link connecting and quantifying the coupled effects of climate change and reservoirs. More studies are needed to develop a comprehensive understanding of the future impacts of climate change and reservoir operation on extreme events in the LMRB, as well as adaptation and mitigation measures.

Texte intégralRésumé :
AbstractIn this chapter, the precipitation threshold at which debris floods occur was evaluated experimentally, and the factors that influence debris flood occurrence, including the bed slope, sediment layer thickness, sediment grain size, length of alluvial flow direction, precipitation intensity, and time of debris flood occurrence, were examined. The impacts of these factors on debris flood initiation were investigated through dimensional analysis. Then, a method was developed to estimate the precipitation intensity threshold based on a set of laboratory tests. Furthermore, different methods for determining the precipitation intensity threshold at which debris floods are initiated were assessed and discussed. The results of the experiments showed that the effect of the sediment layer thickness on debris flood occurrence can be ignored. Moreover, by independently evaluating the effect of each factor on debris flood occurrence, it was found that the sediment length and average diameter of sediments are influential to debris flood initiation. The results of this research provide a better understanding of debris flood mechanisms and occurrence thresholds of debris floods and can be employed to prepare a forecasting model.

Texte intégralRésumé :
AbstractThe behaviors and impacts of flash floods (FF) are different based on the climatic regions. To understand such difference, two case studies were selected for the analysis: Wadi Uday, Oman and Sume Basin, Paraiba, Brazil. The rainfall-runoff inundation model (RRI) was used to simulate the discharge and flood inundation of the recent flood events to understand the severity and frequency of flash floods to better assess the current mitigation measures. The current FF situations in arid and semiarid basins were analyzed, and the hazards associated with flood phenomenon were assessed for various calculated rainfall return periods using RRI model. To this end, a flash flood index (average water depth per total basin area) was calculated as a basis to understand the impact of flash floods. A coupling of this index with the FF histories was included to provide a comprehensive overview of the FF vulnerability of arid and semiarid basins. We concluded that FFs tend to be more severe and extreme in arid regions than in semiarid regions, despite the lower frequency of FFs and the water scarcity in arid regions. Distributed dams also proved to be more effective in preventing FFs in arid regions than in semiarid regions.

Texte intégralRésumé :
AbstractDespite massive flood controlling investments, perennial flooding continues to be a major challenge in the Greater Accra Metropolitan Assembly in Ghana. Previous studies have mostly considered the vulnerability of Accra to flooding induced by urbanization and climate change. This chapter examined the impacts of and adaptation strategies to flooding in two flood-prone residential areas in Accra. A survey was conducted among 320 household heads to ascertain local impacts of floods and community adaptation strategies. To obtain a broader picture of government interventions and challenges, key stakeholders such as personnel from ministries, departments, and agencies who are involved in city planning, and private urban planning consultants were interviewed. The study found that a notable driver of floods in Accra is blocked waterways, and flawed and ad hoc engineering works. About three-quarters of the households interviewed have suffered flood-related losses over the past decade such as housing damage, income, and even a death of a relative. Key flood control interventions included dredging prior to start of rains and sporadic demolition of unauthorized buildings on or near waterways to allow free flow of water. However, these interventions only seem to be ephemeral due to the rapid rate of littering and re-siltation of the waterways after few rain events. The study highlights the need for more pragmatic and robust engineering solutions to build resilience of Accra to floods.

Texte intégralRésumé :
AbstractThis chapter canvasses the latest developments in the modelling and communication of environmental extremes, with a focus on floods. Three scenarios are explored. The first refers to real-time prediction, including the current modelling basis that is adopted, and the visualisation/communication strategies in place. The second refers to an environmental extreme event that is conditional to a failure scenario, as is the case when an existing infrastructure (i.e. levee or spillway in an extreme flood) fails. The third, more complex scenario is the occurrence of a compound or joint extreme, possibly in the future, where extreme storms will intensify. A compound extreme here could represent a flood event that follows from an incident of rare storm conditions on a fire-damaged landscape. While the modelling challenges are significant, visualisation is even more challenging, as the scenario occurs under a hypothetical future. Demonstrating how coupled models can support the anticipation of extreme event scenarios, the chapter considers implications for risk assessment and communication that can support future preparedness and resilience. Surveying knowledge gaps that still need to be bridged, the authors formulate a list of key requirements in the fields of data availability, processing and representation.

Texte intégralRésumé :
Floods are one of the deadliest natural disasters in the world. According to the World Meteorological Organization (WMO), this is a consequence of the increasing frequency of heavy precipitation, changes in upstream land use, and a continuously increasing concentration of population and assets in flood-prone areas [1]. For this reason, flood prevention, and protection are a growing priority these days. Flood hazard mapping is a state-of-the-art tool for decision-makers and stakeholders when it comes to flood protection and Flood Risk Management Plans. The visualization of the various parameters (range, depths, velocities, etc.) of a flood event gives a clear vision for implementing measures that help to protect and restore the natural functions of rivers and floodplains. This article presents the different types of flood hazard maps - with either a single parameter or a combination of several parameters (range, depths, velocities, and combination of flow velocity and flow depth. For this purpose, results obtained from 2D modeling with the software product HEC-RAS were used. The digital terrain model used was provided by Drone and has a resolution of 0.05 cm. Land cover information from CLC 2018 was used to determine the Manning coefficients. According to Art. 146e. of the Water Act (New, SG No. 61/2010) [2], several scenarios should be considered for Bulgaria: low-probability floods, medium-probability floods, and high-probability floods. As a result, a number of maps with different probabilities of flood occurrence and different flood parameters were obtained. These maps were used to analyze and assess potential damage in the different flood scenarios and parameters.

Texte intégralRésumé :
Abstract The industry and academia have continued efforts for aiming more oil recovery by focusing on certain ions in low salinity water (LSW) brine composition with variety of mechanism hypotheses. This paper reviews past history, findings, and the latest focus for exploring upside potentials of LSW EOR in carbonate reservoirs. Based on recent research focused on fluid-fluid interaction (FFI), forming micro-dispersion (MD) as an interfacial reaction of oil-water mixing, we highlight useful additives which can boost the interactions and improve LSW EOR gains. The majority of past LSW EOR investigation have been focusing on rock-fluid interaction, therefore, the subsequent engineered LSW investigation have been conducted from the perspective of reducing positive-charged carbonate rock surface by adding negative-charged materials such as sulfate ions. However, this approach is not practical from operational and/or reservoir management viewpoints due to scaling and reservoir souring risks. Together with sulfate ions, certain positive-charged cations have been also investigated to prevent oil droplets absorbing on rock surface by connecting with negative-charged components in oil. In recent, beyond the common investigated ions, new ions such as copper and chromium were reported to improve LSW EOR effect. Those efforts should be admired; however, it should point out uncertainties in the rock-fluid-interaction-oriented investigation in case of carbonates, because inconsistencies are often observed between screening stage results such as spontaneous imbibition tests and oil recovery evaluation results in core floods. In parallel with the engineered LSW optimization based on the rock-fluid interaction, the different approach was established based on the FFI as highly practical and consistent evaluation. The approach relied on micro-dispersion ratios (MDR) representing water content increment by the oil-water interfacial reactions because the oil recovery improving magnitude was demonstrated well correlating with MDR. Namely, aiming further oil recovery is equivalent to boost the FFI between LSW and positive oils. In the most recent research, three additives for pure LSW (diluted to 1% sea water): diethyl ketone (DEK), dimethyl ketone (DMK), and copper chloride were investigated as a sensitivity analysis from the perspective of MDR improvement and core flood tests. The ketones revealed noticeable increase of MDR more than double of that in pure LSW case. The tertiary oil recovery after sea water injection stage consistently increased +3%, +5%, and +11% IOIP for pure LSW, LSW+Cu(II), and LSW+DEK cases, respectively. A monotonous correlation was observed between those additional oil increment and MDR. Subsequently, a molecular-level fluid analysis using Fourier-transform ion cyclotron resonance mass spectrometer elucidated certain components taking main roles of FFI mechanism. Based on the functional components, further optimization of engineered LSW designs is expected as way forward.

Texte intégralRésumé :
Since ancient times, mankind has tried to establish a causality of the phenomena that occur in the surrounding world, to find solutions and answers. Floods are widespread in the Danube Delta they cause great material damage and loss of human life and important consequences. The production of floods in the Danube Delta is due to the entry into the Danube of large amounts of water from rains, from the sudden melting of snow and mountain glaciers, as well as from underground water sheets. Deforestation favors the rapid runoff of water on the slopes and the production of heavy floods. Risks can be classified either according to the mode of manifestation (slow or fast) or according to the cause (naturales au anthropique). They produce smaller or larger damages depending on their amplitude and the favorable factors in the place or region where they manifest. In order to identify the risk, the emerging risks must first be identified, there are a number of risk identification and evaluation methodologies. In the present work, several flood scenarios will be analyzed for the Patlageanca locality in the Danube Delta using two flood risk analysis methods. Flood risk analysis methods will be applied using two specialized programs that perform flood scenarios at different water levels. The main database is represented by the digital land model for the town of Patlageanca. The digital model together with the data collected in the field such as bathymetric information, flows and water levels are the starting source for the flood risk analysis of the target locality. The results provide information on the depth of water on flooded portions and the extent of flooded areas. The results presented in this paper can provide concrete support to the authorities who have decision-making power to establish action measures to intervene in the reduction of flood risk. Therefore, the present work represents a sum of several engineering methods that, applied, can contribute to the creation of flood maps for a locality located in an area at risk of flooding. Flooding can cause particularly significant damage in the Danube Delta, especially on the main arms where there are human settlements. For this reason, multiple points of view, methods, hypotheses and future possibilities adapted to new trends (social, economic, natural) and determined by different factors, play an important role in flood risk management and in establishing flood vulnerable areas.

Texte intégralRésumé :
Data on historic floods along the Danube River exist since the year 1012. In the Middle Ages, floods were estimated based on historical documents, including original handwritten notes, newspaper articles, chronicles, formal letters, books, maps and photographs. From 1500 until the beginning of organized water regime observations, floods were hydraulically reconstructed based on water marks on old buildings in cities along the Danube (Passau, Melk, Emmersdorf an der Donau, Spilz, Schonbuhen and Bratislava). The paper presents a procedure for assessing the statistical significance of registered historic floods using a comprehensive method for defining theoretical flood hydrographs at hydrological stations. The approach is based on correlation analysis of two basic flood hydrograph parameters – maximum hydrograph ordinate (peak) and flood wave volume. The PROIL model is used to define the probability of simultaneous occurrence of these parameters. It defines the exceedance probability of two random variables, in the specific case two hydrograph parameters of the form: P{Qmax more equal to qmax,p)∩(Wmax more equal to wmax,p)} = P (1) where: Qmax – maximum hydrograph ordinate (peak); qmax,p – maximum discharge of the probability of occurrence p; Wmax – maximum hydrograph volume; wmax,p – maximum flood wave volume of the probability of occurrence p; P – exceedance probability. Spatial positions of the lines of exceedance of two flood hydrograph parameters and the empirical points of the corresponding parameters of the considered historic flood in the correlation field Qmax - Wmax, allow direct assessment of the exceedance probability of a historic flood, or its statistical significance. The proposed procedure was applied in practice to assess the statistical significance of the biggest floods registered along the Danube in the sector from its mouth to the Djerdap 1 Dam. The linear trend in the time-series of maximum annual flows at a representative hydrological station and the frequency of historic floods in the considered sector of the Danube are discussed at the end of the paper.

Texte intégralRésumé :
Accurate streamflow prediction is critical for ensuring water supply and detecting floods, while also providing essential hydrological inputs for other scientific models in fields such as climate and agriculture. Recently, deep learning models have been shown to achieve state-of-the-art regionalization performance by building a global hydrologic model. These models predict streamflow given catchment physical characteristics and weather forcing data. However, these models are only focused on gauged basins and cannot adapt to ungaugaed basins, i.e., basins without training data. Prediction in Ungauged Basins (PUB) is considered one of the most important challenges in hydrology, as most basins in the United States and around the world have no observations. In this work, we propose a meta-transfer learning approach by enhancing imperfect physics equations that facilitate model adaptation. Intuitively, physical equations can often be used to regularize deep learning models to achieve robust regionalization performance under gauged scenarios, but they can be inaccurate due to the simplified representation of physics. We correct such uncertainty in physical equation by residual approximation and let these corrected equations guide the model training process. We evaluated the proposed method for predicting daily streamflow on the catchment attributes and meteorology for large-sample studies (CAMELS) dataset. The experiment results on hydrological data over 19 years demonstrate the effectiveness of the proposed method in ungauged scenarios.

Texte intégralRésumé :
This report summarizes a review of technologies used to monitor bridge scour with an emphasis on techniques appropriate for testing during and immediately after design flood conditions. The goal of this study is to identify potential technologies and strategies for Illinois Department of Transportation that may be used to enhance the reliability of bridge safety monitoring during floods from local to state levels. The research team conducted a literature review of technologies that have been explored by state departments of transportation (DOTs) and national agencies as well as state-of-the-art technologies that have not been extensively employed by DOTs. This review included informational interviews with representatives from DOTs and relevant industry organizations. Recommendations include considering (1) acquisition of tethered kneeboard or surf ski-mounted single-beam sonars for rapid deployment by local agencies, (2) acquisition of remote-controlled vessels mounted with single-beam and side-scan sonars for statewide deployment, (3) development of large-scale particle image velocimetry systems using remote-controlled drones for stream velocity and direction measurement during floods, (4) physical modeling to develop Illinois-specific hydrodynamic loading coefficients for Illinois bridges during flood conditions, and (5) development of holistic risk-based bridge assessment tools that incorporate structural, geotechnical, hydraulic, and scour measurements to provide rapid feedback for bridge closure decisions.

Texte intégralRésumé :
We study the impact of floods on the education outcomes of high school students in Bangladesh. We construct satellite image-based measures of flood at the union level and combine them with the census data of all high schools for the years 2011-2018. Exploiting within-union variations of the flood measures, we find that the passing rates of public exams and school-based exams of the secondary schools in a union drop significantly if greater areas of that union are flooded. In the case of public exams, for example, the passing rates decreased by 4-9 per cent if the flooded area of a union increased by 1 per cent after controlling for school and year-fixed effects. The impact is found to be more pronounced for female students - the passing rates of female students were about 2 percentage points lower than the male students in the SSC examinations. While the literature argues that the impact of natural disasters on education outcomes is indirect and long-term, we provide robust evidence suggesting that floods' direct and immediate impact on education outcomes can be substantial. Our results have a significant bearing on education policies and disaster management strategies of natural flood-prone developing countries.

Texte intégralRésumé :
We evaluate whether floods and landslides are more likely when rain falls inside versus outside protected areas (PAs). We use monthly municipality data for the period 2000-2015 in Guatemala and monthly district data for the period 1992-2019 in Costa Rica. We define relevant catchment areas using water flows to population centers of administrative units. Then, we calculate the precipitation inside and outside PAs within the relevant catchment areas, and test how the frequency of floods and landslides is affected by whether rain falls inside or outside PAs. We use a two-way fixed effect panel data model. For Guatemala, we find no robust statistically significant effects on these types of disasters. However, in Costa Rica, we find that shifts in precipitation towards PAs reduce floods significantly. These results were highly robust. We also find effects on landslides in densely populated districts, as well as reductions in flood-related deaths.

Texte intégralRésumé :
You are worried about flood impacts from the river that borders your property. While you have
considered building a levee and placing stones along the bank to protect you land and house
from erosion, you do not have the equipment or expertise to do so. Additionally, you have seen
water velocity in the river increase because the farmer upstream has channeled the river. You
blame the farmer for putting your land and house at greater flood risk. You think that upstream
land should be allowed to flood to slow water velocity and absorb floodwaters; this would
protect you and your neighbors from future floods.

Texte intégralRésumé :
This paper presents a new data fusion multiscale observation product (MOP) for flood emergencies. The MOP was created by integrating multiple sources of contributed open-source data with traditional spaceborne remote sensing imagery to provide a sequence of high spatial and temporal resolution flood inundation maps. The study focuses on the 2015 Memorial Day floods that caused up to US$61 million of damage. The Hydraulic Engineering Center River Analysis System (HEC-RAS) model was used to simulate water surfaces for the northern part of the Trinity River in Dallas, using reservoir surcharge releases and topographic data provided by the US Army Corps of Engineers. A measure of fit assessment is performed on the MOP flood maps with the HEC-RAS simulated flood inundation output to quantify spatial differences. Estimating possible flood inundation using individual datasets that vary spatially and temporally allow an understanding of how much each observational dataset contributes to the overall water estimation. Results show that water surfaces estimated by MOP are comparable with the simulated output for the duration of the flood event. Additionally, contributed data, such as Civil Air Patrol, although they may be geographically sparse, become an important data source when fused with other observation data.

Texte intégralRésumé :
In July 2021, the Rhine-Meuse region straddling Belgium, Germany and the Netherlands was affected by devastating floods that have led to the loss of more than 240 lives and damage worth billions of Euros. The event was closely watched by regional agencies that had to organize response and recovery, and also received noticeable global attention. Diverse sets of responses and reflections accumulated among researchers, local and regional governments, local and international media, development organizations, public offices and citizen groups, wherein links to climate change and gaps in our preparedness for unexpected, extreme events were a common element of the discourse. In response to the floods, and in recognition of the cross-border effects of climate change, the United Nations University institutes in Belgium (UNU-CRIS), Germany (UNU-EHS) and the Netherlands (UNU-MERIT) have launched the “UNU Climate Resilience Initiative” with the aim to share knowledge, shape policy and drive action – and ultimately shift the focus from risk to proactive adaptation, innovation and transformation. Within the context of this initiative, researchers from the three institutes have conducted research in the flood affected areas and organized the two-day “Flood Knowledge Summit 2022: From Risks to Resilience”, which took place from 7 to 8 July 2022 in Maastricht, the Netherlands. Complementing existing national initiatives and efforts in the three countries, the event aimed to connect different actors – including affected citizens, first responders, authorities, researchers and civil society – from the region, the European Union (EU) and the Global South to share experiences, engage in dialogue and facilitate learning regarding how to strengthen climate resilience for all. This summit served to map various efforts to understand the data, information, governance and knowledge gaps at national, subnational and regional levels in order to address growing risks of climate change, including how to adapt to not only climate-induced extreme events like floods but also other hazard events, and created a regional momentum to support multidimensional efforts towards building resilience. Drawing on our research and outcomes of the Flood Knowledge Summit 2022, the UNU Climate Resilience Initiative has identified five key areas in which further research and action is needed to tackle climate risks and facilitate pathways towards climate resilience.
