Since 1980 river floods in Europe have resulted in over 4,700 fatalities and caused direct economic losses of more than €150 billion (2013 values), and future risk is likely to increase due to the combination of climatic and socio-economic drivers. As such, reliable research works are needed to investigate river flood risk under future climate scenarios, and to evaluate adaptation strategies able to limit the impacts of river flooding. In this report, we present results of the PESETA III river flood risk assessment based on an ensemble of high-resolution regional climate scenarios and suitable socio-economic pathways. We evaluated river flood risk in Europe throughout the 21st century by comparing flood impacts under baseline (1976-2005) climate with those in the near (2021-2050) and far (2071-2100) future and under specific warming levels (SWLs) of 1.5, 2 and 3°C global warming above preindustrial levels. Simulated flood risk scenarios are representative for high levels of greenhouse gas concentrations in the atmosphere, and considering both time-based and warming-based scenarios allows to evaluate the influence of the speed of warming on flood impacts. Our analysis includes all EU member states plus a number of neighbouring countries, most of which include parts of European river basins like the Danube. The neighbour countries considered are Bosnia - Herzegovina, Belarus, Iceland, Kosovo, Moldova, Montenegro, the Republic of Macedonia (FYROM), Norway, Serbia and Switzerland. An ensemble of seven regional climate projections from 1970 to 2100 forced by the Representative Concentration Pathway (RCP) 8.5 scenario were run through a distributed hydrological model and resulting streamflow was analysed statistically to estimate future changes in the river flood hazard in Europe. Note that the analysis does not consider other flood processes such as coastal floods (due to storm surges and waves), nor pluvial and flash floods (caused by localized, high-intensity rainfall events). Impacts of river floods in Europe were evaluated by combining the occurrence and magnitude of future discharge peaks with present exposure maps (population, landuse) and information on flood defences. Estimates of expected economic damage and population affected were produced considering first only climatic drivers (static economic analysis) and then including the effects of socio-economic development coherent with the considered climate scenarios (dynamic economic analysis). Furthermore, the risk assessment framework was applied to qualitatively evaluate the risk reduction potential of a number of flood adaptation strategies. Measures taken into account include the rise of flood protection, reduction of the peak flows through water retention, reduction of vulnerability and relocation to safer areas. Under baseline climate, in Europe around 216,000 people are exposed each year to river flooding and annual flood damage amounts to €5.3 billion. In most regions of Europe we see an increase of flood risk due to global warming (see Figure 1). Under a 2°C global warming scenario, which under the RCP8.5 pathway will occur in the early 2040s, and considering current socio-economic conditions, flood impacts could more than double, with 525,000 people annually exposed to floods and €13 billion of expected annual losses. If near term (2021-2050) climate conditions are considered, approximately 450,000 people could be exposed annually to river flooding and direct flood damages could reach €12 billion. Longer term climate conditions (2071-2100) imposed on present society could result in over 700,000 people annually exposed to floods while direct flood damages could see a more than three-fold increase with respect to current conditions, reaching €17 billion of average annual losses.

Floods are of increasing public concern world-wide due to increasing damages and unacceptably high numbers of injuries. Previous approaches of flood protection led to limited success especially during recent extreme events. Therefore, an integrated flood risk management is required which takes into consideration both the hydrometeorogical and the societal processes. Moreover, real effects of risk mitigation measures have to be critically assessed. The book draws a comprehensive picture of all these aspects and their interrelations. It furthermore provides a lot of detail on earth observation, flood hazard modelling, climate change, flood forecasting, modelling vulnerability, mitigation measures and the various dimensions of management strategies. In addition to local and regional results of science, engineering and social science investigations on modelling and management, transboundary co-operation of large river catchments are of interest. Based on this, the book is a valuable source of the state of the art in flood risk management but also covers future demands for research and practice in terms of flood issues.

Approaches to avoid loss of life and limit disruption and damage from flooding have changed significantly in recent years. Worldwide, there has been a move from a strategy of flood defence to one of flood risk management. Flood risk management includes flood prevention using hard defences, where appropriate, but also requires that society learns to live with floods and that stakeholders living in flood prone areas develop coping strategies to increase their resilience to flood impacts when these occur. This change in approach represents a paradigm shift which stems from the realisation that continuing to strengthen and extend conventional flood defences is unsustainable economically, environmentally, and in terms of social equity. Flood risk management recognises that a sustainable approach must rest on integrated measures that reduce not only the probability of flooding, but also the consequences. This is essential as increases in the probability of inundation are inevitable in many areas of the world due to climate change, while socio-economic development will lead to spiralling increases in the consequences of flooding unless land use in floodplains is carefully planned. Flood Risk Science and Management provides an extensive and comprehensive synthesis of current research in flood management; providing a multi-disciplinary reference text covering a wide range of flood management topics. Its targeted readership is the international research community (from research students through to senior staff) and flood management professionals, such as engineers, planners, government officials and those with flood management responsibility in the public sector. By using the concept of case study chapters, international coverage is given to the topic, ensuring a world-wide relevance.

This new handbook brings together various views and experiences of the impacts of flooding and its management in Africa, Asia and Latin America by drawing from traditional and modern approaches adopted by communities, homeowners, academics, project managers, institutions and policy makers. Key stakeholders provide insights and perspectives on flood hazards, flood impacts, flood control and adaptation strategies across these regions. The inclusion of policy makers, emergency responders, leaders of key organizations and managers of flood defence projects makes this volume a unique addition to the flood management literature. The chapters are organized to reveal various impacts and challenges associated with the management of flooding, including response and recovery. The chapter contributions bring together the different impacts of flooding and propose various mitigation approaches. They describe procedures for managing flooding and reducing the impacts from the perspectives of policy makers, environmental planners and restorers of flood-affected communities. Also, the book considers some of the related aspects including land use, waste management, drainage systems, security challenges, urban planning and development and their contributions to flooding. The book's primary target is experienced researchers and practitioners in flood risk management. It would also serve as a key text for postgraduate students studying related programmes. Inhabitants of flood prone communities in such developing countries will also find the text an important resource for guidance and understanding. This multi-disciplinary book represents a valuable contribution for a wide range of professionals (e.g. in engineering, built environment, health, retail, etc) who are interested in flood control and management and/or faced with flood-related challenges in the course of their work.

River stage or flow rates are required for the design and evaluation of hydraulic structures. Most river reaches are ungauged and a methodology is needed to estimate the stages, or rates of flow, at specific locations in streams where no measurements are available. Flood routing techniques are utilised to estimate the stages, or rates of flow, in order to predict flood wave propagation along river reaches. Models can be developed for gauged catchments and their parameters related to physical characteristics such as slope, reach width, reach length so that the approach can be applied to ungauged catchments in the region. The objective of this study is to assess Muskingum-based methods for flow routing in ungauged river reaches, both with and without lateral inflows. Using observed data, the model parameters were calibrated to assess performance of the Muskingum flood routing procedures and the Muskingum-Cunge method was then assessed using catchment derived parameters for use in ungauged river reaches. The Muskingum parameters were derived from empirically estimated variables and variables estimated from assumed river cross-sections within the selected river reaches used. Three sub-catchments in the Thukela catchment in KwaZulu-Natal, South Africa were selected for analyses, with river lengths of 4, 21 and 54 km. The slopes of the river reaches and reach lengths were derived from a digital elevation model. Manning roughness coefficients were estimated from field observations. Flow variables such as velocity, hydraulic radius, wetted perimeters, flow depth and top flow width were determined from empirical equations and cross-sections of the selected rivers. Lateral inflows to long river reaches were estimated from the Saint-Venant equation. Observed events were extracted for each sub-catchment to assess the Muskingum-Cunge parameter estimation method and Three-parameter Muskingum method. The extracted events were further analysed using empirically estimated flow variables. The performances of the methods were evaluated by comparing both graphically and statistically the simulated and observed hydrographs. Sensitivity analyses were undertaken using three selected events and a 50% variation in selected input variables was used to identify sensitive variables. The performance of the calibrated Muskingum-Cunge flood routing method using observed hydrographs displayed acceptable results. Therefore, the Muskingum-Cunge flood routing method was applied in ungauged catchments, with variables estimated empirically. The results obtained shows that the computed outflow hydrographs generated using the Muskingum-Cunge method, with the empirically estimated variables and variables estimated from cross-sections of the selected rivers resulted in reasonably accurate computed outflow hydrographs with respect to peak discharge, timing of peak flow and volume. From this study, it is concluded that the Muskingum-Cunge method can be applied to route floods in ungauged catchments in the Thukela catchment and it is postulated that the method can be used to route floods in other ungauged rivers in South Africa.

Up to 5 million people in the UK are at risk from river and coastal flooding and it is a severe test to the countrys arrangements and flood defence infrastructure. Significant river floods in the UK over the years have prompted changes in flood defence legislation, and encouraged a substantial programme of building flood defences, but the risks still remain significant. This book follows on from the successful ICE Learning to Live with Rivers report in presenting the complete and extensive findings from the ICE Presidential Commission.
