Flood risk management has been studied extensively and intensively in many academic fields from civil engineering, sociology, economics, culture, and even psychology. However, the fact that flooding accounts for a greater number of damaging events than any other type of natural events worldwide on an yearly scale proves that our understanding of flooding is still insufficient, flawed, and fragmented. This chapter intends to shed new light on a number of issues that deserve more comprehensive study in order to advance flood risk management. As a result, a new two-layer framework of vulnerability is proposed, which can lead to a better understanding of, and new approaches to, flood risk management.

This book provides a series of topics on flood risk management from around the world. The first section includes models for improved approaches to flood risk management, the importance of groundwater management in the context of floods (focussing on Taiwan), contingency plan for local communities using flood simulation, deciding on response strategies against the identified flood risk before a flood occurs (illustrated for the Philippines) and models for estimating maximum flood heights (illustrated for Mozambique). The second section examines flood risk management relating to the urban environment, with examples from a coastal city in Saudi Arabia and a housing development in Mexico. The third section relates to flood risk management in the context of agriculture, particularly relating to damage to Asian rice crops.

The past half century has seen an evolution in thinking from ‘flood control’ to ‘flood risk management’, recognizing that risk results from both hazard and vulnerability. Rather than rely only on engineering structures to reduce flood magnitude or extent, recent policies emphasize avoiding construction in flood-prone areas (or moving people from floodplains), reducing impacts on exposed populations through early warning systems, and insurance to aid in recovery. Implementing this new approach faces many challenges but also offers opportunities for synergies, as described in this book for a range of large floodplain rivers and smaller urban streams across North America and Europe. This book is unique in presenting the voices of those on the front lines of implementing a new paradigm in flood risk management, each river with a unique set of challenges and opportunities derived from its specific geography as well as differences in governance between the American and European contexts.

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.

Flood risk management policy across the European Union is changing, partly in response to the EU Floods Directive and partly because of new scientific approaches and research findings. It involves a move towards comprehensive flood risk management, which requires bringing the following fields/domains closer together: the natural sciences, social sc

This valuable edition brings together 25 peer reviewed articles on technical, socio-economic, environmental and policy aspects of flood risk management. Some emerging technologies are presented and several future challenges are identified. Thus the book forms an excellent reference for the engineers, scientists, planners, policy-makers, researchers, insurance industry and all the practitioners involved in flood risk management.

This book deals with the introduction of a new type of “spatial measures" in flood governance. In contrast to traditional “safety measures" that aim to provide protection against floods by building structural flood defenses such as levees and flood walls, the goal of spatial measures is to reduce the exposure to flood risks by changing the spatial layout of flood-prone areas. By limiting developments and flood-proofing buildings in areas at risk to flooding, investments in structural flood defenses can be circumvented and vulnerabilities reduce. World-wide, spatial measures are gaining attractiveness as a response strategy to increasing flood risks caused by climate change and urbanization. The introduction of spatial measures in flood governance involves more than the simple development of new policies and laws. Research has demonstrated that the implementation of spatial measures can have huge implications for how costs and responsibilities are divided between different levels of governance and between public and private actors, changing the whole organization behind flood governance. Both for the effectiveness and for the legitimacy of spatial flood governance strategies, it is important that these distributive implications are well understood. This book describes the introduction of spatial measures in the context of two very different delta countries: the Netherlands and the United States. In the United States, a spatial flood governance strategy was already developed in de mid-20th century whereas in the Netherlands, a safety paradigm institutionalized over the course of the 20th century and spatial measures have only recently been introduced. By analyzing the science-policy interactions underlying the implementation of spatial measures in both countries, this book shows how under the influence of different types of experts (engineers in the Netherlands and social geographers in the United States) different spatial flood management strategies emerged with different distributive implications, each with its own challenges for effectiveness and legitimacy.
