Abstract. Jakarta is the capital city of Indonesia with a population of about 10.2 million people, inhabiting an area of about 660 square-km. It is located within a deltaic plain and passes by 13 natural and artificial rivers. In the last three decades, urban development of Jakarta has grown very rapidly in the sectors of industry, trade, transportation, real estate and many others, which has caused several negative environmental impacts. In turns Jakarta is then prone toward a few natural hazards mainly land subsidence and flooding. In general, based on geodetic measurement methods (e.g. Leveling, GPS surveys, and InSAR), conducted since 1982 up to 2014, it is obtained that land subsidence in Jakarta exhibits spatial and temporal variations, with the typical rates of about 3 to 10 cm year−1. In general, the impacts of land subsidence in Jakarta can be seen in the forms of cracking of permanent constructions and roads, changes in river canal and drain flow systems, wider expansion of coastal and/or inland flooding areas, and malfunction of drainage system. Several areas along the coast of Jakarta already have experienced tidal flooding during high tide periods. These coastal flooding usually occurs in the areas with relatively large subsidence rates. Subsidence in the areas along the rivers which are flowing throughout Jakarta will also worsen the impacts of riverine flooding. The changes in river canal and drain flow systems and malfunction of drainage system due to land subsidence will also aggravate the flooding. Land subsidence will have direct and indirect affects with the flooding in Jakarta, both in coastal or inland areas.

Urban floods can threaten citizens’ quality of life, produce socioeconomic losses, and act as an urban degradation driver. Restoring urban rivers, however, is not simple and its results are usually limited. It would be desirable to enhance urban fluvial systems, control flood risks, and increase city resilience while improving the city itself. This work suggests that river restoration, when applied to an urban watershed, should be supported by sustainable urban drainage measures to compensate for the negative effects induced by city growth in the water cycle, in a systemic approach to the entire watershed. A methodological framework is proposed to verify this hypothesis intending to assess urban flooding projects in a wide sense. This framework uses a hydrodynamic mathematical model and a set of multicriteria indices. A case study in Dona Eugênia Watershed, in Brazil, was developed. Two different design concepts were considered: the usual drainage design and the river restoration combined with sustainable urban drainage. Both solutions were designed to completely solve the problems, leading to virtually zero flooding in the present situation; however, environmental and urban gains were greater when using the proposed combination. Besides, when testing resilience behavior, it was also shown to be more consistent over time.

Surface waters and urban drainage systems are usually studied separately. However there are important interactions between both systems. Urban drainage systems can have an important impact on the surface waters, mainly at combined sewer overflows. On the other hand during periods of high water levels in a river, the runoff from the urban drainage system can be significantly influenced by backwater, which increases the probability of flooding in is not obvious, because the modelling tools for both systems are often hard to combine properly. To properly assess the probability of flooding for this kind of integrated water systems, different submodels are needed for both subsystems. In practice often one single model is used to describe the runoff to rivers despite the presence of urban catchments. The main objective of this study is to show the limits of this simplified approach. Furthermore, it is necessary to use continuous long term simulations, because of the differences in runoff behaviour. Detailed hydrodynamic models do not really fit for this purpose because of long simulation times and high demands in memory and disk space. Therefore simplified conceptual models are more useful.

Urban drainage system involves urban surface runoff, drainage pipeline system and rivers and its dynamic behavior is driven both by natural and artificial forces. There is a lack of appropriate and progressive hydraulic dynamic models for whole urban drainage system, together with much difficulty in collecting operation data, and backwardness of operation control techniques, thereby causing the frequent occurrence of urban flooding, sewage overflow and high energy-consumption of the pump stations. Therefore, it is hard to guarantee the security, reliability and high-efficiency of the operation of the urban drainage networks. To solve these problems, this paper proposed a large closed-loop control system model to achieve multi-objective and comprehensive operation optimization of urban drainage networks, based on the design of a new control model of a progressive system of city runoffs, drainage pipeline network and river tunnels.

Urban flooding is a severe and pervasive hazard caused by climate change, urbanization, and limitations of municipal drainage systems. Cities face risks from different types of floods, depending on various geographical, environmental, and hydrometeorological conditions. In response to the growing threat of urban flooding, a better understanding of urban flood vulnerability is needed. In this study, a comprehensive method was developed to evaluate the vulnerability of different types of urban floods. First, a coupled urban flood model was built to obtain the extent of influence of various flood scenarios caused by rainfall and river levee overtopping. Second, an assessment framework for urban flood vulnerability based on an indicator method was used to evaluate the vulnerability in different flood hazard scenarios. Finally, the method was applied to Lishui City, China, and the distribution and pattern of urban flood vulnerability were studied. The results highlight the spatial variability of flooding and the vulnerability distributions of different types of urban floods. Compound floods were identified to cause more severe effects in the urban areas.

Intense rainfall in urban areas often generates both pluvial flooding due to the limited capacity of drainage systems, as well as fluvial flooding caused by deluges from river channels. The concurrence of pluvial and fluvial flooding can aggravate their (individual) potential damages. To analyse the impact caused by individual and composite type of flooding, the SIPSON/UIM model, an integrated 1D sewer and 2D overland flow was applied to numerical modelling. An event matrix of possible pluvial scenarios was combined with hypothetic overtopping and breaching situations to estimate the surface flooding consequences in the Stockbridge area, Keighley (Bradford, UK). The modelling results identified different flooding drivers in different parts of the study area and showed that the worst scenarios resulted from synthesised events.

The frequency and severity of floods have been found to increase in recent decades, which have adverse effects on the environment, economics, and human lives. The catastrophe of such floods can be confronted with the advance prediction of floods and reliable analyses methods. This study developed a combined flood modeling system for the prediction of floods, and analysis of associated vulnerabilities on urban infrastructures. The application of the method was tested on the Blue River urban watershed in Missouri, USA, a watershed of historical significance for flood impacts and abundance of data availability for such analyses. The combined modeling system included two models: hydrodynamic model HEC-RAS (Hydrologic Engineering Center—River Analysis System) and hydrologic model SWAT (Soil and Water Assessment Tool). The SWAT model was developed for the watershed to predict time-series hydrograph data at desired locations, followed by the setup of HEC-RAS model for the analysis and prediction of flood extent. Both models were calibrated and validated independently using the observed data. The well-calibrated modeling setup was used to assess the extent of impacts of the hazard by identifying the flood risk zones and threatened critical infrastructures in flood zones through inundation mapping. Results demonstrate the usefulness of such combined modeling systems to predict the extent of flood inundation and thus support analyses of management strategies to deal with the risks associated with critical infrastructures in an urban setting. This approach will ultimately help with the integration of flood risk assessment information in the urban planning process.

<p><strong>Abstract.</strong> Space for water is now becoming guiding principle of urban planning because urban flooding is the major problem facing by most of the cities in India. Urban development in developing countries like India usually occurs with high population concentrating in small areas, with poor drainage conditions. People occupy floodplain areas in low flood years and when larger flood occurs it causes high damage. The origin for urban floods is floodplains encroachment and unplanned drainage systems. Complexities in the urban environment and drainage infrastructure have an inherent influence on surface runoff. This runoff generates urban flooding which poses challenges to modeling urban flood hazard and risk. As like in river flooding satellite images are not available for unban flooding scenario. So better modelling provides minimizing loss of life and property. The present study focuses on recognizing the highly effected areas which are liable to flooding when extreme rainfall occurs for part of Hyderabad city (Zone XIII). The entire Hyderabad city is divided into 16 zones and each zone having details of existing drain network. A coupled 1D-2D flood modelling approach is used to identify flood prone areas and develop flood inundation and flood risk maps. 1D model for pilot area is developed using storm water management model (SWMM) and coupled with 2D PCSWMM. A web based GIS platform INPPINS is used to geo reference the existing network details and exported to 1D SWMM model. The model is simulated for extreme flood event occurred in past. The simulation run results identifies overflowing drainage nodes and flood inundation maps and risk maps prepared. The flood risk maps identify the low lying areas which need immediate attention in case of emergency. The overflowing nodes suggest the need of improvement of drainage in the area to safely dispose of the storm water and minimize the flooding.</p>

A bacia do rio Beberibe abrange quatro municípios de Pernambuco e tem significativa importância nos seus sistemas de drenagens urbana. O trecho do baixo Beberibe possui um adensamento populacional intenso, inclusive nas suas margens, que associado ao descarte irregular dos resíduos sólidos, polui e abstrói a calha do rio, que na ocorrência de picos de chuvas, resulta em alagamentos e inundações na área. Na intenção de minimizar esses transtornos, essa pesquisa visa analisar a vazão de cheia da sub-bacia do rio Beberibe, para implementar medidas estruturais e não estruturais de drenagem urbana sustentável. A metodologia utilizada consistiu em simular as vazões de cheia para tempos de retorno de 05 e 10 anos, a partir de hidrogramas de cheias gerados por meio do modelo ABC6. Os resultados demonstraram que a sub-bacia do rio Beberibe tende a uma vazão de pico de 46,61m³/s e 63,95 m³/s, respectivamente. Dessa forma, foram apresentadas áreas permeáveis disponíveis para implementação de reservatórios de detenção, para atuarem como medida de controle de enchente nos períodos de chuvas intensas, além de medidas não estruturais a serem implantadas no entorno do rio e para as comunidades ribeirinhas.Palavras chaves: águas pluvais; modelo hidrológico; alagamentos. Urban Drainage: A Flood Flow Analysis for the Beberibe River Sub-Basin using the ABC6 modelA B S T R A C TThe Beberibe river basin covers four municipalities in Pernambuco and has significant importance in its urban drainage systems. The lower Beberibe stretch has an intense population density, including on its banks, which, associated with the irregular disposal of solid waste, pollutes and drains the river channel, which in the event of rain peaks, results in flooding and flooding in the area. In order to minimize these disturbances, this research aims to analyze the flood flow of the Beberibe River sub-basin, to implement structural and non-structural sustainable urban drainage measures. The methodology used consisted of simulating the flood flows for return times of 05 and 10 years, from flood hydrographs generated through the ABC6 model. The results showed that the Beberibe River sub-basin tends to a peak flow of 46.61 m³/s and 63.95 m³/s, respectively. In this way, permeable areas available for the implementation of detention reservoirs were presented, to act as a flood control measure in periods of intense rainfall, in addition to non-structural measures to be implemented around the river and for riverside communities.Keywords: rainwater; hydrological model; floods.

- Description of the problems

Throughout history floods have been one of the most severe natural catastrophes, which brought about loss of lives and huge economic losses in addition to the influence on community activities and adverse effects on the environment. We have witnessed enormous flood events almost all over the world, even in the early years of 21st century. The cruel lesson learnt is that we have not coped well with floods.

Studying the risk of flooding is the goal of this thesis. The focus is given to flooding of urban drainage systems. Urban climate, human activities and land use vary quickly and greatly with time. These variations modify the features of both urban hydrology and hydraulics, and change the distribution of water. It may lead to dual adverse effects in one region: the severe water shortage in one period and the increasing risk of flooding in another period. Therefore, finding appropriate solutions for these problems has been being a great challenge for the whole world.

- Aims of this study

This study aims to contribute ideal approaches and models to understand deeply urban flooding problems, i.e. to find the causes of flooding, to analyze their propagations and on this basis to evaluate the risk of flooding, and finally to search for solutions for flood mitigation.

- Study contents and methodologies

Distinguishing the potential hazards of urban flooding, delineating the changes of urban lands, developing models to simulate flooding and examining different measures to mitigate the risk of flooding constitute the main contents of this study. It is carried out by both qualitative analysis and quantitative simulations in a stepwise manner. Regarding the stochastic characteristics of flooding, a risk analysis initiates the study, which aims to formulate flooding scenarios in general urban environment through procedures of system definition, hazard identification, causal analysis, frequency analysis, consequence estimation and mitigation. A Norwegian case study illustrates the whole process.

Following the risk analysis, GIS technology is introduced to delineate the variation of topography. GIS hydrological modeling is applied to delineate the basic hydrological elements from a Digital Elevation Model (DEM). The accuracy of grid DEM and the influence of buildings are studied.

Two urban flooding models, the "basin" model and the dual drainage model, are developed on the basis of the MOUSE program (DHI, 2000). The three models, i.e. the MOUSE model, the “basin” model and the dual drainage model, are examined through two case studies, and the flow capacities of the existing sewers in these two case studies are then checked. Following the flooding simulation, the effectiveness of four flooding mitigation measures is tested.

- Main results

Sixty-eight (68) potential flooding hazards are identified by risk analysis in Chapter three. In combination with Trondheim case study, the frequencies of several flooding scenarios are studied, and it is indicated that the flooding of urban drainage systems happens more frequently than river flooding. When it happens, urban flooding disturbs very much the activities in flooding areas. Therefore management attentions should be paid to urban flooding in addition to large river flooding.

GIS is used as a bridge between digital data and numerical flooding simulation. Two important hydrological elements, watersheds and surface stream networks, are derived from grid DEM in Chapter four. The preliminary flood risk zones are delineated in combination with two case studies. They provide useful information for flood management.

The three flooding models are calibrated through two case studies: Trondheim- Fredlybekken catchment in Norway and Beijing-Baiwanzhuang (BWZ) catchment in China. Flooding checking of the existing sewer systems in these two case studies indicates that the current flow capacities of sewers are less than the designed capacities. Consequently, flood mitigation measures are examined in the following Chapter six. The study indicates that the combination of structural and non-structural flood mitigation measures are regarded as the comprehensive solution for flood control.

- Restrictions of the developed models

The developed flood models are restricted to summer and autumn flooding situations. In other words, the snowmelt routine is not included in the hydrological model applied. However, if a hydrological model that is able to simulate snowmelt could be connected to the developed models, then the hydraulic analysis would be carried out similarly.

The research presented in this thesis addressed the performance of Sustainable Urban Drainage Systems (SUDS) at three sites in Scotland - a porous paved car park and two swales. It is the first research to provide results for such systems in the UK and also the first direct comparison between SUDS and traditional systems in situ. The aim of developing guidance on effectiveness and synthesising design recommendations has been achieved with the integration of hydrological and water quality studies together with modeling. Monitoring data and information were analysed on both a site-by-site basis and as a comparison between sites. Hydrological and water quality data were collected at each site. Key hydraulic parameters examined include percentage runoff, initial runoff loss, peak flow reduction and lag time. The term Benefit Factor has been introduced as a volumetric measure used to summarise the hydraulic benefit gained by installing SUDS, as no comparable terminology has yet been used elsewhere. The water quality parameters include physical/ chemical, hydrocarbons and metals. All three sites had low levels of pollution with little scope for water quality improvement, however the changes in water quality did indicate the different processes occurring within the systems. Computer models were built for the porous paving installation and one of the swales, further to understand the processes of source control and to analyse the systems. Hydraulic capacity exceedence criteria were investigated using design storms, and finally the models were used to evaluate improvements to design detailing. The results of this research have shown that, despite being under-designed according to current guidance, all three sites performed very favourably. The performance of porous paving and swales can be similar depending on design and detailing. A number of design recommendations are made as a result of observations and sensitivity analysis, and these should be considered in conjunction with current guidance.

Many urban rivers receive significant inputs of metal-contaminated sediments from their catchments. Their restoration has the potential to increase the deposition and accumulation of these sediments from greater sediment supply and increased channel hydraulic complexity, creating a store of metals which could have negative impacts upon ecosystems and human health. Macrophytes often establish in restored channels and have the potential to stabilise these sediments and uptake metals through processes of phytoremediation, thus reducing the risk of the accumulated sediments becoming a source of metals. This thesis investigates the effects of river restoration upon sedimentation patterns and the interactions between macrophytes and sediments in terms of sediment trapping, stabilisation and metal uptake within urban river systems. At a reach scale, greater finer sediment deposition and the accumulation of sediment around in-channel vegetation was found within restored stretches of tributaries of the River Thames London, reflecting sediment availability and hydraulic conditions. These sediments were important in terms of greater metal storage within stretches, and along with gravels showed particularly high metal concentrations. Interactions between macrophytes, sediment and flow were investigated within the urban-influenced River Blackwater, Surrey. At the stand scale, the common emergent Sparganium erectum was found to significantly reduce flow velocities, accumulate fine sediments and retain them over winter. Research on individual plants revealed that, although three common emergent macrophytes (Sparganium erectum, Typha latifolia and Phalaris arundinacea) did not significantly phytoremediate metal contaminated sediments through metal uptake or bioconcentration, the reinforcement and stabilisation of these accumulated sediments (particularly by Sparganium erectum and Typha latifolia) and the creation of anoxic sediment conditions which strongly bind metals, were important in reducing the risk of metal mobilisation from the sediments. These macrophyte sediment interactions illustrate the great potential of using emergent macrophytes in the restoration and management of urban rivers with metal contaminated sediments.

Flood hazard assessment and mapping is a necessary step to define flood risk reduction strategies and to develop risk management plans. Anyway, in Italy, and in particular in Lombardy Region, legislation provides only vague indications on how to assess flood hazard, therefore the definition of risk is lacking in a scientific basis, and wide space is left to subjectivity and to approximate analyses. This PhD research aims to improve the topic presenting an approach for flood hazard analysis and mapping that fits the Lombardy Region legislative framework, but introduces a level of experimental modelling. The approach has been applied on an area located in the medium Valtellina (Alps, northern Italy) – 26 km2 wide – and makes use of advanced flood modelling tools, in order to support the development of Emergency Plans and to provide suggestions to deepen the analyses required for Urban Planning. Hydrologic and hydraulic conditions of the site are quite complex, and data availability is not optimal. Therefore, several modelling strategies (1D, 2D and combined 1D2D approaches) and three software packages (SOBEK, FLO-2D and FloodArea) were tested and results were compared and discussed. Lots of efforts have been spent in trying to define an accurate topographical description: a TIN was constructed from available 3D cartography and cross sections profiles, then converted into a DEM. Institutional values of peak discharges for the return times of 20, 100 and 200 years were used to construct input hydrographs. Roughness coefficients were set according to literature tables and available local studies, and their influence on models behaviour was tested through sensitivity analyses. Difficulties related to some of the models and/ or verification of inappropriate results led to exclude two software packages and to select SOBEK 1D2D as the most suitable tool for flood modelling in the study area. Results were converted into hazard maps useful for both the purposes of Civil Protection and Urban Planning, basing on an innovative method, including an expression of uncertainty. Most of the complexities of the issue are analysed and discussed, referring to a wide literature background, which the research will contribute to enrich.

The present climate changes constitute one of the main threats to delta and estuary cities. The rise of the mean sea level and the increase of the intensity and frequency of the precipitation extremes are presently raising the flood risk of these territories, jeopardizing their maintenance and future development. The present work focuses on how these climate change processes can raise the risk of the urban drainage flooding events at the cities waterfronts. The relevance of the problem is reinforced by the present incapacity of the urban drainage systems to follow the needed adaptation, forcing the delta and estuary cities to rethink the management of their storm water outflow. Under this view, the main drainage adaptation strategies and measures are analysed, namely in urban planning and design, and on the benefits of the integration of natural processes. To contextualize the addressed problem, the possible drainage flood impacts over the Lisbon riverfront are analysed. The influence of the climate change processes over the current drainage system and the flood risk of this area are shown, demonstrating the need for integration of the drainage problem in the future urban planning.

Streszczenie:
In future cities, urban drainage and flood management systems should be designed not only to reliable during normal operating conditions but also to be resilient to exceptional threats that lead to catastrophic failure impacts and consequences. Resilience can potentially be built into urban drainage systems by implementing a range of strategies, for example by embedding redundancy and flexibility in system design or rehabilitation to increase their ability to efficiently maintain acceptable customer flood protection service levels during and after occurrence of failure or through installation of equipment that enhances customer preparedness for extreme events or service disruptions. However, operationalisation of resilience in urban flood management is still constrained by lack of suitable quantitative evaluation methods. Existing hydraulic reliability-based approaches tend to focus on quantifying functional failure caused by extreme rainfall or increases in dry weather flows that lead to hydraulic overloading of the system. Such approaches take a narrow view of functional resilience and fail to explore the full system failure scenario space due to exclusion of internal system failures such as equipment malfunction, sewer (link) collapse and blockage that also contribute significantly to urban flooding. In this research, a new analytical approach based on Global Resilience Analysis (GRA) is investigated and applied to systematically evaluate the performance of an urban drainage system (UDS) when subjected to a wide range of both functional and structural failure scenarios resulting from extreme rainfall and pseudo random cumulative link failure respectively. Failure envelopes, which represent the resulting loss of system functionality (impacts) are determined by computing the upper and lower limits of the simulation results for total flood volume (failure magnitude) and average flood duration (failure duration) at each considered failure level. A new resilience index is developed and applied to link resulting loss of functionality magnitude and duration to system residual functionality (head room) at each considered failure level. With this approach, resilience has been tested and characterized for a synthetic UDS and for an existing UDS in Kampala city, Uganda. In addition, the approach has been applied to quantify the impact of interventions (adaptation strategies) on enhancement of global UDS resilience to flooding. The developed GRA method provides a systematic and computationally efficient approach that enables evaluation of whole system resilience, where resilience concerns ‘beyond failure’ magnitude and duration, without prior knowledge of threat occurrence probabilities. The study results obtained by applying the developed method to the case studies suggest that by embedding the cost of failure in resilience-based evaluation, adaptation strategies which enhance system flexibility properties such as distributed storage and improved asset management are more cost-effective over the service life of UDSs.

The research programme was relevant to urban planning and in particular to the design of stormwater management schemes that are more environmentally and socially acceptable. It examined social and perception issues relating to stormwater management techniques within residential areas, and in particular to the application of SUDS, mainly ponds, and river management schemes. The thesis arose from a project funded by the Environment Agency of England and Wales through SNIFFER under a programme titled “Social impacts o f stormwater management techniques including river management and SUDS”, SNIFFER Code: SUDS01. The public perception of construction is becoming a matter of increasing importance both in the UK and internationally since socio-economic parameters and public consultation both have to be taken into consideration in the planning and implementation of relevant projects. This research programme endeavoured to match the relevant legislative goals with society’s actual needs. The main aims of the research programme were to obtain an in-depth understanding and knowledge of the perceptions of popular stormwater management practices (SUDS and river management), and to evaluate these techniques from a social perspective. To satisfy these aims the following objectives were set: • To assess public awareness and perceptions of SUDS (particularly retention ponds) in the UK; • To assess professional perceptions of SUDS in the UK; • To assess perceptions of different stormwater management techniques, in three European cities; • To compare perceptions of different stormwater management techniques, SUDS and river management practices; • To link the research findings with trends in perceptions of nature and water. To meet the programme’s aims and to satisfy the objectives, the perceptions of SUDS in the UK (principally ponds) were investigated over a wide range of locations. In addition, the different river management approaches used in three heavily urbanised European cities, Glasgow, London, and Athens were investigated. The results of this research programme provide a means to understand perceptions of stormwater management and to appreciate what types of schemes will be more readily accepted by the public. The research has shown that members of the public hold strong views as to what they like or dislike about SUDS and water management installations in their local area, in spite of the fact that there were demonstrably low levels of public awareness of SUDS. The amenity, recreational value and aesthetics of new schemes seem to be of major importance for public acceptability, while function, efficiency, and maintenance are primarily important in areas facing flooding problems. Other key findings include the fact that there is a general preference for sustainable urban water management and for river restoration schemes compared with more conventional, ‘hard engineering’ approaches, such as culverting of rivers. This preference was expressed both by members of the public and by professionals involved in their planning and implementation. Another important result was that although unfamiliarity can produce negativity, education can influence attitudes positively even in sensitive issues such as safety, and can be used by authorities and planners as a means of enhancing the acceptability of new schemes. Consequently, the results of the surveys can be used as arguments towards the application of informative campaigns which should be taken into account prior to scheme implementation. This information can be utilised not only for stormwater management design, but also for other environmentally friendly constructions which the public may have a low level of awareness. Recommendations are made with respect to public and professional attitudes for improving the public acceptability of new and modified stormwater management systems. Recommendations and barriers to the uptake outlined in this thesis mainly refer to the appearance of schemes rather than technical issues. They are therefore of most use as guidance for improving aesthetics and increasing public acceptability. The outcomes of this research will be of use to policy makers, water companies, local authorities, environment agencies, planners, developers, consultants active in urban development, and researchers in applying wider-accepted practices for the assessment of public perception. Some findings from this research have been presented at several stakeholders’ meetings, at 4 conferences, and are published in the form of papers and reports, including the DTI SR 622 report titled “An Assessment of the Social Impacts of Sustainable Drainage Systems in the UK”, and the Environment Agency & SNIFFER report, SUDS01, 2005, titled “Social Impacts of stormwater management techniques including river management and SUDS”. This publication also constitutes Environment Agency R&D Technical report P2-258.

Streszczenie:
Urban pluvial flooding is stressing urban areas with increasing frequency, becoming a factor of great concern. Soil sealing resulting from urban development is one of the main reasons for changes in natural hydrological processes and related recurring failures of urban drainage systems, especially during heavy rainfall events. Today, several studies are looking at the concept of urban resilience as a new paradigm, for a better integration of issues of water and flood risk with urban planning. Resilience is viewed as a way to tackle risk, showing bonds with its different sections, among which the flood hazard. It is broadly agreed that spatial planning, by incorporating Sustainable urban Drainage Systems (SuDS) within tools and polices, helps to build urban flood resilience. In particular, SuDS, as alternative strategy for surface water management, could potentially address anthropogenically generated hazard, thanks to the water-flow regulating service and benefits they provide. This research explores the relationship between the risk of urban pluvial flooding, resilience and urban planning. Particularly, the concept of resilience is clarified in order to highlight how it contributes to both analyse urban systems by adding levels of knowledge, and steer planning and policy approaches towards the mitigation of pluvial flood risk. By applying a research methodology based on the use of EPA-Storm Water Management Model (SWMM), the main aim of the thesis was to define a proper methodology and to build-up an analytical tool in order to analyse and assess the urban system s response to rainfall events, and to be used during and for purposes of the planning process. The proposed methodology is open to be flexibly applied to aptly handle the previous issues. Accordingly, the purpose was twofold: to assess the impact of masterplan in terms of increase of flow peak releases from urban catchments concerned by planned urban developments; to examine the urban system s reaction to rainfall and to evaluate how the response is affected by SuDS implementation at the catchment level. Case study areas were selected in the cities of Catania and Avola, in Sicily, for which masterplans design has been recently proposed by local planning authorities. Simulation of scenarios were carried out for a number of design storm events of selected return periods. Input parameters for the modelling were derived from urban analyses and hydrologic analyses and processing. Firstly, the methodology was based on the comparison between pre- and post-development catchment release scenarios and was applied to a case study catchment in the southern part of Catania. The study showed the need of careful consideration of the hydraulic invariance principle in land use planning practices. In particular, a set of flow release restrictions were determined for new areas of development, achieving the condition of unvaried flow peaks at the sub-catchment level, for different return periods of the storm-water event. Secondly, the methodology was applied to selected urban catchments in the centre of Avola. SWMM was used to track the quantity of runoff generated within each sub-catchment, and the flow rate and flow depth of water in each pipe in order to profile the system response to rainfall-runoff simulation. A dual-drainage approach was used to simulate the interaction between the minor and the major drainage systems and to obtain local flood characteristics to be mapped. Moreover, different effectiveness of selected SUDS measures were demonstrated in terms of improved water-flow regulation service and flood hazard mitigation, by comparing scenarios of pre- and post-implementation. Thesis discussion reflects the need for planning emphasis on mitigation and translating the understanding about risk, resilience and sustainable drainage into decisions via effective policy mechanisms. Suitable tools are needed to encourage a drainage-sensitive urban development and retrofitting.

Streszczenie:
This dissertation's urban vision looks at the environmental issues of land, water and the health of the people of Vanderbijlpark, all of which have been affected by heavy industry. The study sets out to address the deteriorating quality of the Vaal River's water and how this is affected by the tributaries feeding into it. This dissertation will focus on the remediation and monitoring of the contaminated water through an ecosystemic approach. The programme involves the removal of heavy metals from the industrial effluent from the surrounding heavy industry that flows into the Rietspruit Canal. The potential of micro-organisms, plants and insects will be explored as elements of a natural treatment system of the contaminated water. The site identified for the remediation processes is an abandoned parcel of land - a remnant of the natural landscape after urban sprawl. The algae and wetland treatment system will run through the facility, becoming the spine for the remediation process and movement through the facility. The production of silk, its uses and by-products will be integrated to support the overall system which treats the contaminated water. The facility aims to address the community's need to express their voice on environmental and health issues by integrating a community auditorium and exhibition space. The construction and materiality is grounded in the premise that the local companies will remain supportive and collaborative in the environmental intervention in the Rietspruit Canal system, into which they contribute considerable effluent. It will also be proposed that the local companies will fund and supply various steel products for the construction of the intervention. This will form part of the company's corporate social responsibility and a way of giving back to fringe communities affected by industry.
Die stedelike visie vir hierdie verhandeling fokus op die omgewingskwessies van grond, water en die gesondheid van die mense van Vanderbijlpark wie almal geraak word deur swaar nywerhede. Die studie spreek die verswakkende kwaliteit van die Vaalrivier se water aan en hoe dit geraak word deur sytakke wat daarin vloei. Die verhandeling sal fokus op wyses waarop besoedelde water deur middel van 'n ekosistemiese benadering herstel en gemonitor kan word. Die program behels die verwydering van swaar metale uit die industri?le uitvloeisel van die omliggende swaar nywerhede wat in die Rietspruit-kanaal vloei. Die potensiaal van mikro-organismes, plante en insekte as elemente van 'n natuurlike stelsel vir die behandeling van die besoedelde water, word ondersoek. Die terrein wat geidentifiseer is vir die herstelprosesse is 'n verlate stuk grond, 'n oorblyfsel van die natuurlike landskap na stadspreiding. Die stelsel vir die behandeling van alge en vleilandhabitatte sal deur die fasiliteit loop en die ruggraat van die herstelproses vorm. Die produksie van sy en die gebruike en neweprodukte daarvan sal geintegreer word om die totale sisteem wat die besoedelde water behandel, te ondersteun. Die fasiliteit het ten doel om die behoefte van die gemeenskap om hul stemme oor omgewings- en gesondheidskwessies te verhef, aan te spreek deur die gemeenskapsamfiteater en uitstalruimte te integreer. Die konstruksie en materialiteit is gegrond op die veronderstelling dat die grootste staalnywerheid, ArcelorMittal, ondersteunend en samewerkend sal wees ten opsigte van die omgewingsingryping in die Rietspruit-kanaalsisteem, waartoe hul aansienlike uitvloeisel bydra. Daar sal ook voorgestel word dat die swaar nywerhede die befondsing asook verskeie staalprodukte vir die oprigting van die fasiliteit sal verskaf. Dit sal deel uitmaak van die maatskappy se korporatiewe sosiale verantwoordelikheid en is 'n manier om aan gemeenskappe wat deur die industrie geaffekteer word, terug te gee.

This book traces the emergence of the South Indian city of Kanchi as a major royal capital and multireligious pilgrimage destination during the era of the Pallava and Chola dynasties (circa seventh through thirteenth centuries). It presents the first-ever comprehensive picture of historical Kanchi, locating the city and its more than 100 spectacular Hindu temples at the heart of commercial and artistic exchange that spanned India, Southeast Asia, and China. The author demonstrates that Kanchi was structured with a hidden urban plan, which determined the placement and orientation of temples around a central thoroughfare that was also a burgeoning pilgrimage route. Moving outwards from the city, she shows how the transportation networks, river systems, residential enclaves, and agrarian estates all contributed to the vibrancy of Kanchi’s temple life. The construction and ongoing renovation of temples in and around the city, she concludes, has enabled Kanchi to thrive continuously from at least the eighth century, through the colonial period, and up until the present.

Streszczenie:
Angkor, the capital of the Khmer Empire in Southeast Asia, was the most extensive low-density agrarian-based urban complex in the world. The demise of this great city between the late 13th and the start of the 17th centuries AD has been a topic of ongoing debate, with explanations that range from the burden of excessive construction work to disease, geo-political change, and the development of new trade routes. In the 1970s Bernard-Phillipe Groslier argued for the adverse effects of land clearance and deteriorating rice yields. What can now be added to this ensemble of explanations is the role of the massive inertia of Angkor’s immense water management system, political dependence on a meticulously organized risk management system for ensuring rice production, and the impact of extreme climate anomalies from the 14th to the 16th centuries that brought intense, high-magnitude monsoons interspersed with decades-long drought. Evidence of this severe climatic instability is found in a seven-and-a-half century tree-ring record from tropical southern Vietnam. The climatic instability at the time of Angkor’s demise coincides with the abrupt transition from wetter, La Niña-like conditions over Indochina during the Medieval Warm Period to the more drought-dominated climate of the Little Ice Age, when El Niño appears to have dominated and the ITCZ migrated nearly five degrees southward. As this transition neared, Angkor was hit by the double impact of high-magnitude rains and crippling droughts, the former causing damage to water management infrastructure and the latter decreasing agricultural productivity. The Khmer state at Angkor was built on a human-engineered, artificial wetland fed by small rivers. The management of water was a massive undertaking, and the state potentially possessed the capacity to ride out drought, as it had done for the first half of the 13th century. Indeed, Angkor demonstrated just how powerful a water management system would be required and, conversely, how formidable a threat drought can be. The irony, then, is that extreme flooding destroyed Angkor’s water management capacity and removed a system that was designed to protect its population from climate anomalies.

Water is scarce in the Lake Eyre Basin in the heart of Australia. The region goes through natural cycles of boom and bust, and the flooding of the basin rivers is accompanied by spectacular responses from wildlife and vegetation. However, the Lake Eyre Basin faces the threat of diversion of water from rivers and wetlands and development of floodplains for irrigation and mining. Around the world, such water resource developments have caused widespread degradation of rivers and loss of habitats. Lake Eyre Basin Rivers outlines the environmental, social and economic values of the rivers from a diverse range of perspectives, including science, tourism, economy, engineering, policy, Traditional Owners and pastoralists. It describes the current state of the environment and the past and ongoing threats to the river systems, drawing on stories from the Murray-Darling Basin. It also provides direction for ensuring that the rivers remain free-flowing to service the environment and future generations. This book is a valuable reference for environment and government agencies, industries and policy-makers concerned with the region and will be of interest to the communities of the Lake Eyre Basin.

Pastoral Australia tells the story of the expansion of Australia's pastoral industry, how it drove European settlement and involved Aboriginal people in the new settler society. The rural life that once saw Australia 'ride on the sheep's back' is no longer what defines us, yet it is largely our history as a pastoral nation that has endured in heritage places and which is embedded in our self-image as Australians. The challenges of sustaining a pastoral industry in Australia make a compelling story of their own. Developing livestock breeds able to prosper in the Australian environment was an ongoing challenge, as was getting wool and meat to market. Many stock routes, wool stores, abattoirs, wharf facilities, railways, roads, and river and ocean transport systems that were developed to link the pastoral interior with the urban and market infrastructure still survive. Windmills, fences, homesteads, shearing sheds, bores, stock yards, travelling stock routes, bush roads and railheads all changed the look of the country. These features of our landscape form an important part of our heritage. They are symbols of a pastoral Australia, and of the foundations of our national identity, which will endure long into the future.

AbstractThe Ciliwung River in Java, Indonesia, is known to cause frequent flooding in the downstream capital city of Jakarta. From source to mouth the river flows through several administrative units. Indonesia’s decentralised governance structure means that each unit has the authority to develop its own plans and to address its own objectives. Not only that, but flood management spans many sectors, and these sectors need to work together throughout the decentralised governance system. This can pose a significant challenge to achieving integrated river management to mitigate flooding, where plans need to be carefully coordinated and high levels of collaboration are required. This chapter examines the current governance arrangements in the Ciliwung River Basin, to understand what challenges may be preventing successful coordination of flood management. The findings of the study are based on a systematic review of the literature conducted within the frame of the NERC and RISTEK-BRIN funded project: Mitigating hydrometeorological hazard impacts through improved transboundary river management in the Ciliwung River Basin. The findings suggest several issues that restrict the effectiveness of coordination for flood mitigation in the Ciliwung Basin. Imprecisely defined roles and responsibilities, issues including lack of capacity at the local level, insufficient coordination between local administrations, and limitations to the function of coordination platforms are some of the challenges identified. The findings highlight that coordination challenges do not only exist at basin scale, but that coordination issues beyond the basin can also have an impact. Overall, the chapter presents insights into the coordination challenges facing flood governance in urban transboundary basins. It also provides insights for practitioners on what aspects of river governance may need to be improved to support flood risk reduction, as well as potential topics for future research.

AbstractUrban flooding is an increasing hazard and expected to aggravate with climate change. The opening of a piped urban river in Copenhagen is explored to mitigate urban flooding as a result of a rising groundwater table. In the Copenhagen case study, a hydrological model has been used to calculate the effect of reopening a currently piped river to its natural environment as a nature-based solution (NBS). From the results of modelling scenarios, we have set up a simple damage function to calculate the avoided costs for the river basin by comparing difference in groundwater levels with and without NBS.Stakeholders were engaged from the first stages of the case study. The integration of stakeholder’s knowledge in the co-design and implementation process of NBS to support complex decision-making processes was carried out by (1) participatory modelling activities to elicit and structure stakeholder’s risk perception, (2) mapping the interaction among decision-makers and stakeholders, and by (3) deriving Fuzzy Cognitive Maps (FCM) from Group Model Building.The results show that by reopening the river, an economic benefit is obtained because the river now functions as a drainage channel which prevents flooding by groundwater of subterranean structures, notably housing cellars, and receives stormwater from cloudburst rainfall events. The FCM simulation showed that NBS implementation requires effective cooperation among different decision-makers to define potential interventions and to reduce the level of conflicts and to facilitate collaborative decision-making.

One of the main causes of land subsidence in the world is the exploitation of groundwater above the regeneration capacity of the aquifer systems. However, the rapid urban growth in estuarine areas can also contribute to the development of this phenomenon. An example of this occurs in the city of Recife, northeastern Brazil. The municipality is built on an estuarine plain composed of several rivers (Capibaribe, Beberibe, Tejipió), which formation results from the occupation of humid areas and mangroves. In recent decades, the excessive removal of water resources from the subsoil has caused the reduction of more than 100 meters of the deep aquifer piezometric level in some places. The presence of these factors in Recife may contribute to land subsidence. To detect this phenomenon, the Persistent Scatterer Interferometric Synthetic Aperture Radar (PSInSAR) technique was used. The dataset consisted of 135 Sentinel-1A Interferometric Wide (IW) Single Look Complex (SLC) images from September 2016 to April 2021. The images were acquired in descending orbits and VV polarization. The results of the PSInSAR analysis reveal that in Recife there are several areas of land subsidence with a rate close to -15 mm/year. The main occurrence of soil settlement is observed in large recently built areas in the west zone, and small areas in the north zone. Minor cases occur in the southern zone due to the exploitation of groundwater. The identification of these land subsidence areas can help in the study of urban drainage to avoid flooding sites and in the adoption of mitigating measures for the suitable use of underground water resources.

The Litoral-Cota 100 zone represents approximately 25% of the total area of the Region of Valencia and concentrates more than 70% of the urban area. One of the consequences of this situation has been the high urban developments produced in the last 50 years. The Comunitat Valenciana has a river flood hazard mapping, according to which, in the Litoral area, more than 80% of the flood hazard is concentrated. As a result of the experienced urban development and the extent of flooding, there is a significant number of people and property exposed to flood hazards. In order to analyze in detail the urban morphology on the coast and its interaction with floods, research has focused on the specific area of the final section of the Girona River, in the province of Alicante. Specifically, in the municipalities of Els Poblets, El Verger, Denia and Beniarbeig, located in the surroundings of the Girona River, very different urban morphologies have been generated that are not adapted to the existing flood hazard. The analysis carried out allows us to conclude that, despite the significant expansion of urban land, existing urban morphology offers ample possibilities to reduce the risk of flooding. It is proposed the integration of overflows in the built city, avoiding the consolidation of non-built land and designing particular measures on affected buildings. These measures of adaptation to the problem will generate a resilient urban morphology.

<p>Mary Elmes Bridge is a 66m single span Pedestrian and Cyclist bridge opening in Cork, Ireland in July 2019. In September 2016, Cork City Council launched a competition for a single span – no supports in the river were allowed- pedestrian crossing over the River Lee between the historic bridges of St. Patrick’s (a stone arch form 1860’s) and Brian Boru (a former rolling bascule from 1920). The competition was launched as part of Cork City Councils key objective to encourage greater sustainable travel in the form of walking and cycling within the city Centre.</p><p>Constrained by heavy trafficked quay roads, the design of a single span 66m crossing was a real challenge when taking into account that the flooding level for the 200years return is 400mm higher than the existing footpaths. The winning solution is a slender, steel shallow through beam with a slight arching effect. The main span is fully integral with the abutments with the central steel box girder and variable width cantilevered walkways joining at both landing points to a stiff concrete piled foundations. The concept adopts a clever strategy to integrate at grade landings with existing footpath levels while making the structure compatible with future city flood defenses. The use of the pedestrian walkway as a flange in the longitudinal direction allows the structure to achieve a significant slenderness.</p><p>This proposal establishes a connective dialogue with its surrounds and compliant with challenging flooding and visual requirements.</p>

This summary reviews evidence on the urban flooding impact, risk factors, and management and mitigation measures in Lagos and other cities in Nigeria. Flooding is a common problem every year in many cities across Nigeria, but the impacts of flooding are poorly documented. There is no consistent set of statistics at a national or sub-national level that can be used to compare the impacts of flooding across cities, and reports that focus on particular flood events are often incomplete. The literature notes the principal factors contributing to flood risk including uncontrolled urban growth, inadequate and poorly-maintained drainage systems, solid waste management practices, weakness in institutional capacity and coordination, and warning systems and public awareness. The evidence base for flood impacts, risks, and mitigation efforts at the city level in Nigeria is limited, and much of the information available is low quality, inconsistent, or outdated. Many rely on surveys of city residents rather than objective empirical data, and some of these surveys appear to be poorly designed. A significant number of the academic publications available have been published in non-mainstream journals without the usual level of academic peer review. Recent information is scarce, and a significant amount of the available evidence dates from 2011 and 2012, which coincides with an episode of nationwide flooding that was among the worst in Nigeria’s history.

The goal of Northern Colorado Plateau Network (NCPN) riparian monitoring is to determine long-term trends in hydrologic, geomorphic, and vegetative properties of wadeable streams in the context of changes in other ecological drivers, stressors, and processes. This information is intended to provide early warning of resource degradation and determine natural variability of wadeable streams. This report summarizes NCPN monitoring of Courthouse Wash in Arches National Park (NP) from 2010 to 2019. The focus of this report is to (1) present geomorphology and vegetation data from five reaches monitored in Courthouse Wash from 2010 to 2015, and (2) examine patterns in water availability at one monitoring reach from November 2010 to December 2019. Vegetation sampling and geomorphology surveys were suspended in 2016 due to budget cuts; this report presents baseline data for future comparisons. The NCPN has five monitoring reaches located between the inflow of Sevenmile Canyon, a major tributary, and the terminus of Courthouse Wash, at the Colorado River. Two reaches (2, 5) are located in Upper Courthouse Wash, and three (1, 4, 7) in Lower Courthouse Wash. Hydrologic monitoring wells are installed only at Reach 1. During our monitoring period, which included drought years in 2012 and 2018 and a wetter-than-average period from fall 2013 to 2014, groundwater levels showed steep declines corresponding to the start of the growing season each year. Hot, dry summers and falls in 2012, 2018, and 2019 showed the deepest troughs in groundwater levels. Active monsoon years helped elevate summer and fall groundwater levels in 2013 and 2014. Continued monitoring will help us better understand the relationship of climate and water availability at this reach. A geomorphic survey was completed once for reaches 2, 4, and 7, and twice for reaches 5 and 1. Powerful floods during our monitoring period resulted in aggradation of the channel in reaches 5 and 1, which were first surveyed in March 2013. Flooding in September 2013 resulted in an average of 0.24 meters of deposition found in the channel thalweg at Reach 1 in March 2014. Storm events in May 2014 caused additional aggradation. In March 2015, an average of 0.41 meters of deposition was recorded in the channel thalweg at Reach 5, with 0.32 meters of deposition between the vegetation transect headpins compared to the 2013 data. The riparian vegetation recorded at our monitoring reaches is consistent with an open-canopy Fremont cottonwood woodland with a diverse understory. Canopy closure ranged from 29% to 52%. Measurements were sensitive enough to detect a 10% reduction in canopy closure at Reach 5 during a pest infestation in June 2013. Canopy closure subsequently rebounded at the reach by 2015. Total obligate and facultative wetland cover ranged from 7% to 26%. Fremont cottonwood seedlings, saplings, and overstory trees were present at all reaches, indicating good potential for future regeneration of the canopy structure. These data can serve as a baseline for comparison with future monitoring efforts. One area of management concern is that exotic-plant frequency and cover were relatively high in all monitoring reaches. Exotic cover ranged from 2% to 30%. High exotic cover was related to years with high cover of annual brome grasses. High cover of exotic grasses is associated with increased wildfire risk in southwestern riparian systems, which are not well-adapted to fire. Managers should be prepared for this increased risk following wet winters that promote annual brome grass cover. Beaver activity was noted throughout bedrock-constrained reaches in Courthouse Wash. Beaver activity can reduce adjacent woody riparian vegetation cover, but it also contributes to maintaining a higher water table and persistent surface water. Climate change is likely to be an increasingly significant stressor in Courthouse Wash, as hotter, drier conditions decrease water levels and increase drought stress...
