Abstract:
People in flooded areas are exposed to the risk of infectious diseases like gastroenteritis via contact with contaminated floodwater. The burden of such diseases has often been estimated using DALYs based on the severity and duration of the disease symptoms but not for psychology. We hypothesized that people in developing countries hit by floods frequently have higher stress related to flood-related diseases than others. This study aimed to describe the psychological impact of floods into the health burden of diarrhea in flood-prone areas in Thua Thien Hue province, Vietnam in 2016. A cross sectional study was conducted from August to September 2016 in Thua Thien Hue province to ask about their feeling about flood-caused diarrhea compared with common diseases which are leading causes of morbidity in the region. The results showed that the participants felt that some diseases such as diarrhea happened more frequently during and after floods. People in non-flooded areas felt that diarrhea and cough that happened more frequently during and after floods were significantly higher than in other areas. The severity/uncomfortableness of diarrhea that participants reported compared with each common disease was significantly different between people in flooded and non-flooded areas. No significant difference between the newly modified disability weight of diseases that participants in flooded and non-flooded areas, felt happened more frequently related to floods. The feeling to diarrhea disease was not affected by floods. A new method to incorporate the psychological impacts of floods into the burden of normal diarrhea was also proposed. Our findings suggest that floods changed the feelings of people in flooded areas about diarrhea by accepting this disease.

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.

Abstract:
Jakarta, as the capital city of Indonesia, is one of the most flooded areas in Indonesia. The floods occurred annually and heavy floods usually occurred once in a few years. This paper address the geographic distribution of floods and statistical analysis of the floods causes by using rain intensity, tidal height, elevation, and floods occurrence as the parameters. This research was conducted in Angke (Kapuk) and Penjaringan Districts, located in Northern Jakarta where the floods usually occur. The result shows that rainfall intensity, remaining water inundation from the previous flood, and land runoff coefficient as the key factors of flooding in these areas.

Abstract:
AbstractA reliable flood event inventory that reflects the occurrence and evolution of past floods is important for studies of flood hazards and risks, hydroclimatic extremes, and future flood projections. However, currently available flood inventories are based on single-sourced data and often neglect underreported or less impactful flood events. Furthermore, traditional archives store flood events only at sparse geographic points, which significantly limits their further applicability. Also, few publicly available archives contain all-inclusive records of potential natural flooded area over time. To tackle these challenges, we construct two types of multisourced flood event inventories (MFI) for all river basins across the contiguous United States covering the period 1998–2013 on daily and subcatchment scales, which is publicly available at http://flood.umd.edu/download/CONUS/. These archives integrate flood information from in situ observations, remote sensing observations, hydrological model simulations, and five high-quality precipitation products. The first inventory (MFI-Actual) includes all actual floods that occurred in the presence of flood protection infrastructures, while the second, “natural (undefended)” inventory (MFI-Natural) reconstructs the possible “historical” floods without flood protection, which could be more directly influenced by climate variation. In the proposed two inventories, 2,755 and 4,661 flood events were estimated, respectively. MFI-Natural reconstructed 1,597 floods in ungauged basins, and recovered 608 extreme streamflow events in gauged subcatchments where floods would have happened if there were no flood protection. There is an average of four upstream dams located in these flood-recovered subcatchments, which indicates that modern flood defenses efficiently prevent significant flooding from extreme precipitation in many catchments over the country.

Abstract:
AbstractFloods, particularly urban flash floods, frequently disrupt traffic, constraining mobility and exposing motorists to danger. Flood risk managers educate the public on the dangers of driving through flooded roadways, yet losses to life and property continue to occur. This study integrates cultural psychology and risk perception theory to explore how cultural and situational factors influence motorists’ behavior during flash floods. Flood risk managers in Tucson, Arizona, collaborated in the development of a questionnaire mailed to local residents in 2007. Self-reported levels of trust, self-efficacy, social incorporation, and situational factors were analyzed with respect to whether respondents stated that they have or have not driven through a flooded roadway. Respondents demonstrate complex reasoning when confronted with flooded roadways, rather than simple or consistent risk-taking or risk-avoidance behaviors. Participants indicate high levels of trust in official warning messages and share information about floods within their social networks, highlighting the success of education campaigns. However, flood conditions are not always clear, so motorists seek additional sources of information and weigh the dangers against other situational factors on a case-by-case basis. Factors that influence respondents’ decisions include the prior successful crossing of other vehicles, presence of signs and barricades, presence of passengers, risk of personal injury or damage to the vehicle, and the availability of flood-related information. The results also show that individuals who know how to avoid floods, including by asking others for advice, are less likely to enter flooded roadways, and thus communicating further instructions will empower more motorists to avoid danger.

Abstract:
American cranberry (Vaccinium macrocarpon) production sites are often flooded for pest control and crop harvest. However, little is known about how this practice affects vines. A survey was conducted in Massachusetts over a 3-year period to determine the effect of spring, fall, and winter floods on total nonstructural carbohydrate concentration (TNSC) of cranberry uprights of four cultivars. With a few exceptions, TNSC generally was unaffected or increased during the course of the 1-month “late water” flood held from mid-April to mid-May. The 48-hour “flash” flood, held in mid- to late May, generally had little effect on vine TNSC. Fall “harvest” floods, which ranged in duration from 3 to 27 days, often resulted in a decrease in TNSC, with greater decreases in TNSC occurring in early fall floods compared to late fall floods. Decreases in TNSC during the harvest flood were as great as 42%. “Winter” floods had little effect on TNSC. Path coefficient analysis indicated that flood duration, date of application, water temperature, and dissolved oxygen concentration all impacted vine TNSC during the flood, while floodwater depth had little effect. Water clarity (i.e., light penetration to the vines during the flood) also appeared to have little impact. Due to the frequent observation of TNSC decline during fall flooding, it is possible that yield potential of cranberry vines is reduced by current flooding practices.

<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>

Abstract:
Mapping spatial data is essential for the monitoring of flooded areas, prognosis of hazards and prevention of flood risks. The Ganges River Delta, Bangladesh, is the world’s largest river delta and is prone to floods that impact social–natural systems through losses of lives and damage to infrastructure and landscapes. Millions of people living in this region are vulnerable to repetitive floods due to exposure, high susceptibility and low resilience. Cumulative effects of the monsoon climate, repetitive rainfall, tropical cyclones and the hydrogeologic setting of the Ganges River Delta increase probability of floods. While engineering methods of flood mitigation include practical solutions (technical construction of dams, bridges and hydraulic drains), regulation of traffic and land planning support systems, geoinformation methods rely on the modelling of remote sensing (RS) data to evaluate the dynamics of flood hazards. Geoinformation is indispensable for mapping catchments of flooded areas and visualization of affected regions in real-time flood monitoring, in addition to implementing and developing emergency plans and vulnerability assessment through warning systems supported by RS data. In this regard, this study used RS data to monitor the southern segment of the Ganges River Delta. Multispectral Landsat 8-9 OLI/TIRS satellite images were evaluated in flood (March) and post-flood (November) periods for analysis of flood extent and landscape changes. Deep Learning (DL) algorithms of GRASS GIS and modules of qualitative and quantitative analysis were used as advanced methods of satellite image processing. The results constitute a series of maps based on the classified images for the monitoring of floods in the Ganges River Delta.

Abstract:
In terms of scale and devastating consequences, floods are the most dangerous thing among natural disasters. The article is an attempt to assess their impact on the settlements and economic development in the Ob-Irtysh river system within the West Siberian region in the 18th — early 20th centuries. Floods which had high waters were associated with spring floods, but the water could not subside until the fall or even before the ice break. There were also catastrophic ones with a very high level. In addition, some complications such as long high-water cycles accrued at the time when the level and frequency of flooding increased. During severe and catastrophic floods settlements and agricultural land were flooded, livestock died, houses and outbuildings were destroyed or rendered unusable, and communication routes were interrupted for a long time. In the north of the region (Lower Ob region) during catastrophic floods, fishing trade was almost stopped and the opportunities for cattle breeding in the flooded floodplain were sharply reduced. Floodplain agriculture fell into decay during high-water cycles in the southern boreal forest area. The population of coastal areas tried to protect themselves from flooding with storage dams, but they were not built everywhere and often could not withstand the pressure of water. The only effective means of flood defense was relocation to high river banks. Therefore, the floods in 1912 and 1914 years provoked the relocation of the Irtysh River low-cost residents of the Tobolsk province. The authorities facilitated this relocation. Assistance was provided to flood victims, even though not so often. In these conditions, the population often had to rely only on themselves and God’s help. Thus, for example, in the city of Berezov the cult of St. Epiphanius was formed. On his Memorial Day people asked the higher forces for help in eliminating the consequences of the flood. But the most effective tool in combating floods was folk natural science knowledge. Over the long history of life on the river, the Russian population has developed omens, which helped them to judge the level of the upcoming flood. Among the enlightened part of the local population, there were ideas about the cyclical nature of catastrophic floods.

Abstract:
Die vorliegende Habilitation beschäftigt sich mit verschiedenen Aspekten des Hochwasserrisikos in Deutschland. In zwölf Artikeln werden neue wissenschaftliche Erkenntnisse über Hochwassergefahren, über Faktoren, die Hochwasserschäden beeinflussen, sowie über effektive private Vorsorgemaßnahmen präsentiert. So wird die jahreszeitliche Verteilung von Hochwasser in ganz Deutschland gezeigt. Weiterhin werden mögliche Auswirkungen des Klimawandels auf Abflussverhältnisse und Häufigkeiten von Hochwasserereignissen am Beispiel des Rhein-Einzugsgebietes abgeschätzt. Ferner wird am Niederrhein simuliert, welche Auswirkungen Deichbrüche haben können. Hochwasserschäden stehen im zweiten Teil der Arbeit im Fokus: Nach dem August-Hochwasser 2002 wurden ca. 1700 Privathaushalte telefonisch befragt. Damit konnten die Einflüsse verschiedener Faktoren, wie der Überflutungsdauer oder der Verunreinigung des Hochwassers mit Öl, auf die Höhe von finanziellen Schäden quantifiziert werden. Daraus ist zum einen ein neues Modell entstanden, mit dem Hochwasserschäden großräumig berechnet werden können. Zum anderen konnten Hinweise für die Verbesserung der privaten Vorsorge abgeleitet werden. Beispielsweise zeigte sich, dass versicherte Haushalte schneller und besser entschädigt werden als Nicht-Versicherte. Ebenfalls wurde deutlich, dass verschiedene Bevölkerungsgruppen, wie Mieter und Hauseigentümer, unterschiedliche Möglichkeiten haben, Vorsorge zu betreiben. Dies ist zukünftig in der Risikokommunikation zu berücksichtigen. In den Jahren 2005 und 2006 waren Elbe und Donau wiederum von Hochwasser betroffen. Eine erneute Befragung von Privathaushalten und Behörden ermöglichte, die Verbesserung des Hochwasserrisikomanagement und der Vorsorge am Beispiel der Stadt Dresden zu untersuchen. Viele Methoden und Erkenntnisse dieser Arbeit sind in der wasserwirtschaftlichen Praxis anwendbar und tragen somit zur Verbesserung der Hochwasserrisikoanalyse und des Risikomanagements in Deutschland bei.
This thesis deals with different aspects of flood risk in Germany. In twelve papers new scientific findings about flood hazards, factors that influence flood losses as well as effective private precautionary measures are presented. The seasonal distribution of flooding is shown for the whole of Germany. Furthermore, possible impacts of climate change on discharge and flood frequencies are estimated for the catchment of the river Rhine. Moreover, it is simulated at reaches of the Lower Rhine, which effects may result from levee breaches. Flood losses are the focus of the second part of the thesis: After the flood in August 2002 approximately 1700 households were interviewed by telephone. By this, it was possible to quantify the influence of different factors such as flood duration or the contamination of the flood water with oil on the extent of financial flood damage. On this basis, a new model was derived, by which flood losses can be calculated on a large scale. On the other hand, it was possible to derive recommendations for the improvement of private precaution. For example, the analysis revealed that insured households were compensated more quickly and to a better degree than uninsured. It became also clear that different groups like tenants and homeowners have different capabilities of performing precaution. This is to be considered in future risk communication. In 2005 and 2006, the rivers Elbe and Danube were again affected by flooding. A renewed pool among households and public authorities enabled us to investigate the improvement of flood risk management and the precaution in the City of Dresden. Several methods and finding of this thesis are applicable for water resources management issues and contribute to an improvement of flood risk analysis and management in Germany.

Abstract:
This research explores the views, beliefs and knowledges of experts responsible for flood management in Bangladesh. As one of the most disaster-prone nations on Earth, and in response to the neglect of power-holding experts within the existing literature, this project analyses the differences between academic accounts of flooding, labelled the ‘prevailing understanding’, and the local expertise of those responsible for management. Relative to the entrenched narrative, local experts are surveyed and an alternate interpretation is constructed using their knowledge. This combination of textual and perception-based analyses accounts for the complex interrelations between competing forms of knowing. It is on this juxtaposition that the research contributes to new knowledge. The thesis is based on research conducted in Bangladesh between November 2007 and March 2008. To accomplish its objectives, using prominent debates as entry points, academic and government sources are used to account for the lineage of the prevailing understanding. On the basis of this narrative, qualitative interviews with 54 experts explore the construction of flood management knowledge and its relationship with decision making. The experts describe and justify understandings of flood management that are contextual, adaptive and indefinite, challenging many of the assumptions associated with the prevailing understanding. The findings inform several findings: that individuals close to the poverty line are uniquely vulnerable; that disasters merge with management to produce second-generation events; and that a hybrid socio-physical context is both a product and a producer of flood management knowledge. Overall, despite the already complex issue of flooding, managers in Bangladesh consider increasingly issues as diverse as poverty, environmental sustainability and economic and human development. Given the scope of the controversy surrounding flood management, the findings show how analyses of competing knowledges, assumptions and framings can aid the interrogation of prevailing knowledge to generate original findings

Abstract:
Floods are extreme events that can rapidly alter water and habitat quality in receiving estuaries. Because floods are unpredictable, they are more difficult to study, so have received less research attention than freshwater flow studies, resulting in a paucity of information on their ecological effects in the coastal zone. Previous studies have shown correlations between high flow periods and increased fisheries catches, which suggests that floods stimulate productivity in receiving waters. However, there have been no studies providing direct links between floods and increased productivity responses in fisheries species. In addition, the long-term effects of deposited flood sediment on food webs in estuaries are poorly understood. Floodwaters can carry high loads of fine sediment, which settles at the most offshore portion of the estuary delta, known as a prodelta. Nutrients, trace elements and other substances are also exported from the catchment dissolved in floodwater or attached to fine sediment particles and are deposited in estuaries. However, the processes of nutrient release from suspended sediments and settled sediments, and uptake of nutrients and trace elements into the food web in receiving estuaries are not well understood. Therefore, this thesis used laboratory experiments (Chapter 2 & 3) to study these processes with the aim of gaining a better understanding of the mechanisms underpinning measured ecological flood responses using field studies (Chapter 4 & 5). This study used catchment soils formed from three distinct rock types (granite, basalt and sandstone) from the Brisbane River (Queensland, Australia) catchment in a flood simulation experiment to quantify the rates of nutrient release during flooding (Chapter 2). In the laboratory, the fine fraction (<63 µm) of the soils was tumbled in freshwater for three days and left to settle in seawater for four weeks, and filtered water samples were taken throughout. A thin layer of the fine soils was also added to incubated sediment cores collected from central Moreton Bay, Queensland, Australia, to measure the influx or efflux of dissolved nutrients from sediments. Basalt soils, in particular, were relatively nutrient-rich and released substantial quantities of organic and inorganic dissolved nutrients, particularly phosphate. However, when soils were added to estuarine sediment cores and incubated, there was a net influx of phosphate from the overlying water. All soils continually released ammonium in both experiments, indicating that catchment soils may be an important source of ammonium to fuel productivity within the coastal zone. Catchments can also contribute trace elements to estuaries and coastal areas. Sources of trace element (cadmium (Cd), manganese (Mn) and zinc (Zn)) accumulation in estuarine fisheries species occupying different trophic levels were determined using radioisotope experiments (Chapter 3). Clams, prawns and fish common to estuaries on the East Australian coastline were exposed to a combination of Cd, Mn and Zn in three sources: dissolved in seawater, attached to suspended sediment particles, and diet. The study showed that clams accumulated all three elements from seawater, while prawns and fish showed negligible uptake. This indicates that clams may be an important link between dissolved and bioavailable elements for higher trophic level species, since the clams bioconcentrated these elements from seawater. The suspended sediment exposures had similar outcomes, with accumulation by clams, with negligible uptake by prawns and fish. Clams may therefore be particularly sensitive to accumulation of contaminants during floods, which may be exacerbated by their sessile nature. Biokinetic modelling using moderate environmental metal concentrations showed that diet was the main source of Cd and Zn accumulation in clams, whereas seawater was likely to be the main source for clam Mn accumulation. Diet was found to be the main source of Cd, Mn and Zn accumulation in prawns and fish, which is supported by previous studies. In the diet exposures, there was also a considerable difference in assimilation efficiencies between prawns and fish. The results of this study suggest that the contribution of diet to trace element accumulation at higher tropic levels may be larger than previously thought, and diet should therefore be considered in trace element studies involving high trophic level species. To identify short-term responses to a flood, multiple condition indices were determined for brown tiger prawns collected before and after a large cyclone-driven flood from several sites in central Moreton Bay (Chapter 4). Prawns collected from sites closest to the Brisbane River and Moreton Island showed no consistent change in condition over time. However, prawns collected from the most southern sites closest to the Logan River, which was the most severely flooded river system during the storm, responded positively to the flood with increased condition measured in terms of length-weight relationships, carbon-nitrogen ratios and muscle lipid content. Peak condition was measured on the first post-flood sampling occasion (i.e. day 11), and prawns collected 53 d after the flood were found to be in a similar condition to those before the flood. This peak in prawn condition coincided with an increase in benthic algal biomass that occurred simultaneously, measured as chlorophyll-a concentrations. Unlike previous studies, which found negative flood condition responses in fish in urban estuaries, the results from this study show that floods in South East Queensland can increase food web productivity in Moreton Bay. Water conditions in estuaries following floods usually return to normal within a couple of months, therefore long-term flood effects are likely to be caused by catchment sediment that is deposited on the estuary prodelta. To assess catchment influences on energy flow to fish and prawns living on flood prodeltas, common fish and prawn species were analyzed for stable isotope and trace element composition (Chapter 5). Fish and prawns were collected from a prodelta in an urbanized catchment (Moreton Bay) and three non-urbanized catchments (Gulf of Carpentaria). Links between diet and trace element composition were found. Differences in trace element composition were greatest between fish and prawns, which was reflected in correlations of trace elements with nitrogen isotopes. Differences within fish and prawn groups were also found, which were correlated to carbon isotopes and reflected benthic versus pelagic diets of different species. These correlations also highlight the importance of diet in trace element accumulation, and show that trace elements can be useful in food web studies. Variations in diet between locations were measured for some species, particularly catfish, suggesting that material exported from the catchment during floods influences food webs through availability of quality prey in estuary prodeltas. Catfish in Moreton Bay were found to be feeding at a high trophic level, suggesting that the urbanization of the Brisbane River catchment does not negatively affect the quality of food available in the Brisbane River prodelta. Overall, the results of this thesis showed that floods, and the sediments they transport to estuaries, can be beneficial for fisheries and food webs in receiving estuaries. In addition, trace element accumulation is linked to diet, and stable isotopes and trace elements can be combined to study catchment influences on estuarine food webs. An effective and transferrable methodology for mapping catchment influences and evaluating food quality in important fisheries habitats was identified. Floods facilitate a seaward transport of water, sediment and substances from catchments that are taken up into food webs in the coastal zone. Flood frequency and intensity is expected to increase with a changing climate and the work presented here fills important knowledge gaps on ecological responses to floods. While organisms have responded to and recovered from flood events throughout history, changes to sediment and water volumes through land clearing and damming of rivers may affect the quality of food, and therefore fisheries productivity, in the coastal zone. This study therefore has important implications for management of land use, erosion and water resource allocation within catchments.

Abstract:
Ancient Cataclysmic Floods were the Ice Age Floods that left erosional and depositional features and preceded the Missoula Floods (15-18,000 ka) in the Pacific Northwest of the United States (Allen et al., 2009). All previously studied ancient sites were visited (14) and new sites (11) were found; four Missoula Flood quarries were also visited; a total of 29 sites were studied in this thesis. The use of calcrete paleosols to provide relative age dates for flood deposits was analyzed in this thesis. Missoula Flood gravel pits were sampled in order to examine the degree of calcrete development in flood deposits of known ages. All of the Missoula Flood deposits tested contain Stage 1 calcrete soil development. Calcrete paleosols at sites with evidence for older floods were all analyzed. Eight sites have paleosols with Stage II development (3-12% CaCO3): Rulo Outcrop, Potholes Coulee, Leslie Road, Benge, E. Callaway Road, Collier Coulee, Palouse, and Connell. Five sites have paleosols with Stage II+ development (12-17% CaCO3): Brown Road, Leslie Road, Benge, Reese Coulee, and Connell. Fourteen sites have paleosols with Stage III development (17-35% CaCO3): The Dalles, Rulo Outcrop, Winans Road 1, Poplar Heights, Yakima Bluffs, Canal Outcrop, Othello Canal, Reese Coulee, Potholes Coulee, E. Callaway Road, Frenchmen Coulee, Macall, Ritzville, and East Connell. One site has a paleosol with Stage III+ development (35-50% CaCO3): Othello Canal. Ancient Cataclysmic flooding initiated in the Early Pleistocene, at least 1.5 Ma. Sixteen field sites show evidence for Early Pleistocene flooding, preserved in all six provinces: Othello Channels, Columbia River Gorge, Cheney-Palouse Scabland, Quincy Basin, Pasco Basin, and the Walla Walla Valley. There are 26 field sites with evidence for Middle Pleistocene flooding, present in all regions except Othello Channels. Eleven of those 26 sites also show evidence for Early Pleistocene floods. Evidence for Early and Middle Pleistocene floods is present over a wide distribution of elevations from 117 to 524 meters.

Abstract:
Floods are a recurrent natural disaster in Guatemala. Heavy and prolonged rainfall often results in floods that affect people’s life and property. Several institutions and policy instruments at local, national or transnational level address flood management. The purpose of this study is to provide useful insights of the institutional aspects of integrated flood management at local, national and transboundary level in Guatemala. Papers I and II, explore institutions at local level, paper III at national level, while paper IV addresses flood management institutions at transboundary level. This research found that for the local and national level, there are several institutions concerned with flood management. In contrast, at transboundary level, and especially for international rivers, flood management institutions are largely absent. At local level, the Local Councils for Development (COCODEs, the acronym in Spanish) are responsible for flood prevention and preparation. While some municipalities are active in flood prevention, response and recovery activities, their limited economic and technical resources restrict their scope of action.  Local stakeholders such as COCODEs, farmers groups and other actors are largely neglected in the decision making process. The National Coordinator for Risk Reduction to Disasters (CONRED, Coordinadora Nacional para Reducción de Desastres), the Secretariat for Planning and Programming of the Presidency (SEGEPLAN, Secretaría de Planificación y Programación de la Presidencia), the Guatemalan Ministry of Infrastructure and other national institutions are in charge of planning and implementing flood management strategies, leaving public involvement of local actors mainly to public consultation. At the Central American level, the Coordination Centre for Natural Disasters Prevention in Central America (CEPREDENAC, Centro de Coordinación para la Prevención de Desastres Naturales en América Central), an institution part of the Central American Integration System (SICA by Spanish acronym), shall promote transboundary cooperation regarding disaster management, including flood management. However, transboundary flood management faces several challenges: territorial disputes and sovereignty issues over international rivers are significant obstacles to the implementation of integrated flood management programs.

Approved for public release; distribution is unlimited
Floods are the nation's greatest natural disaster. According to the U.S. Geological Survey, floods cause an average of $6 billion of property damage, claim 140 lives, and prompt more Presidential disaster declarations per year than any other hazard. The Federal Emergency Management Agency (FEMA) is the lead for federal response to natural disasters. FEMA was the lead agency in 1993 when floods caused an estimated $1 8 billion in damage in the Midwest. The scope and damages of this historic disaster led FEMA to change its approach to floodplain management, flood protection, flood mitigation, disaster response, and recovery. FEMA and federal emergency response further evolved following the terrorist attacks on September 11, 2001 and Hurricane Katrina in 2005. The latest changes resulted in a national response framework for all levels of government to prepare and respond to all natural and manmade hazards. In 2008, the Midwest experienced its second "500-year flood" in fifteen years. This thesis examines whether changes to national disaster response and investments in flood mitigation over the last fifteen years have improved preparation, protection, and response capabilities at the federal, state, and local levels.

Abstract:
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.

Abstract:
Floods are one of the biggest natural disasters, causing significant economic and human losses. Regardless of the degree of development of urban or rural systems, floods account for about a third of all-natural disasters globally. Identifying areas vulnerable to floods is essential for better management and mitigation of their effects. The research aims to identify areas vulnerable to floods in the city of Codlea, Brașov County. Annually, the city records significant floods, one of the determining factors being its location, near the southern slope of the Perșani Mountains. The research proposes the Flash Flood Potential Index (FFPI) computation by combining GIS techniques with the Frequency Ration bivariate statistical model. The correlation of various flash-flood conditioning variables allowed us to compute the FFPI. The methodological approach could represent an essential tool for local authorities for better flood risk management.

Abstract:
Lagos faces increasingly severe annual flooding, exacerbated by sea level rise and subsidence. In 2021, floods again submerged vehicles and houses, displacing thousands from their homes. The demand for sand in construction materials drives illegal sand mining and erosion on the coast of Nigeria, degrading ecosystems and increasing flood risk. This technical background report for the 2021/2022 edition of the Interconnected Disaster Risks report analyses the root causes, drivers, impacts and potential solutions for the Lagos floods through a forensic analysis of academic literature, media articles and expert interviews.

Abstract:
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.

Abstract:
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.

Abstract:
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.
