Floods are natural events, but when they impact on human environments, they turn into disasters which disrupt society. The last decades have seen an alarming increase in the number of major floods and associated damage on every continent. The impact is more severe due to population growth and settlement in flood prone areas, climate change and disrupted hydrological cycles. There is now an urgency regarding the exchange of information on developments and experiences in research, policy and management. The 3rd International Symposium on Flood Defence presented new developments in Sciences (hydrology, ecology, flood modelling and forecasting, information management and GIS-based decision support systems); Frameworks (institutional and organisational, basin-wide flood management); Policy-making and implementation (government strategies and approaches, public awareness and participation, new concepts such as risk management in relation to climate change); and Measures and solutions (structural and non-structural measures, spatial planning). Case studies illustrate specific experiences and practices in flood control situations, for example, flooding in urban areas. These Symposium Proceedings include about 165 selected papers, presentations, keynotes and theme reports as presented during the ISFD3. As a whole this publication reflects a worldwide change in strategy: from flood defence towards flood management. Floods, from Defence to Management is of special interest to researchers, scientists, consultants, managers, donor agencies and government bodies involved in policy making and flood management.

This book is open access under a CC BY-NC 4.0 license. This revised, updated textbook presents a systems approach to the planning, management, and operation of water resources infrastructure in the environment. Previously published in 2005 by UNESCO and Deltares (Delft Hydraulics at the time), this new edition, written again with contributions from Jery R. Stedinger, Jozef P. M. Dijkman, and Monique T. Villars, is aimed equally at students and professionals. It introduces readers to the concept of viewing issues involving water resources as a system of multiple interacting components and scales. It offers guidelines for initiating and carrying out water resource system planning and management projects. It introduces alternative optimization, simulation, and statistical methods useful for project identification, design, siting, operation and evaluation and for studying post-planning issues. The authors cover both basin-wide and urban water issues and present ways of identifying and evaluating alternatives for addressing multiple-purpose and multi-objective water quantity and quality management challenges. Reinforced with cases studies, exercises, and media supplements throughout, the text is ideal for upper-level undergraduate and graduate courses in water resource planning and management as well as for practicing planners and engineers in the field.
