Human settlements have grown near watercourses since ancient times. Water supply, irrigation, navigation, wastewater conveyance and city defense are some of the uses that were responsible for this choice. Even floods played an important role, favoring the soil fertilization. Man-made actions, however, especially in urban watersheds, significantly modify the natural water cycle, increasing the magnitude of floods and their potential damages. Consequently, flood damages are one of the most important issues to be dealt with in the present days. Several different studies show that floods are one of the most important natural hazards, with several losses, both in terms of lives and money. Particularly in urban areas, the amplification of floods may cause important economic losses and lead to critical social risks to the cities and their population, when inundation reaches the built environment. This situation is becoming more frequent each day. Recent history shows that urbanization is an inevitable trend and, today, the most part of the world population lives in cities. It is difficult, however, to adequately manage urban flood problems, because flood risk and flood costs are not easy to quantify. Traditionally, flood risk and flood cost assessments face difficulties due to the subjective nature of these evaluations and to the inexistence of standardized methodologies.This book tries to show different techniques and approaches to help in treating flood problems. Chapters 1 and 2 show simplified mathematical modeling of floods and results of multifunctional landscape flood control measures in the city of Rio de Janeiro. The remaining book chapters present remedial works against debris after floods in Venezuela and Measures for Mitigation of Flood areas in Japan. There are also presented studies related with Flood Risk Assessment and Management in Mediterranean Basins. The final chapter shows an interesting study related to the attitudes of residents in the Tokyo Bay area toward flood hazards.

This book presents selected papers from the 7th International Conference on Water and Flood Management,with a special focus on Water Security under Climate Change, held in Dhaka, Bangladesh in March 2019. The biennial conference is organized by Institute of Water and Flood Management of Bangladesh University of Engineering and Technology. The recent decades have experienced more frequent natural calamities and it is believed that climate change is an important driving factor for such hazards. Each part of the hydrological cycle is affected by global climate change. Moreover, increasing population and economic activities are posing a bigger threat to water sources. To ensure sustainable livelihoods, safeguard ecosystem services, and enhance socio-economic development, water security needs to be investigated widely in a global and regional context.

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.

Debris and hyper-concentrated flows are among the most destructive of all water related disasters. They affect both rural and urban areas in a wide range of morphoclimatic environments, and in recent years have attracted more and more attention from the scientific and professional communities and concern from the public due to the death toll they claim. The increased frequency of these natural hazards, coupled with climatic change predictions and urban development, suggests that they are set to worsen in the future. This book contains the edited versions of the papers presented at the third International conference on Monitoring, Simulation, Prevention and Remediation of Dense and Debris Flows. The Conference brought together engineers, scientists and managers from across the globe to discuss the latest scientific advancs in the field of dense and hyper-concentrated flows, as well as to improve models, assess risk, develop hazard maps based on model results and to design prevention and mitigation measures. The papers have been organised into the following sections: Debris Flow Modelling; Debris Flow Triggering; Risk Assessment and Hazard Mitigation; Sediment Transport and Debris Flow Monitoring & Analysis.

When in doubt, throw it out. Don't risk injury or infection. 2: Ask for help. Many people can do a lot of the cleanup and repairs discussed in this book. But if you have technical questions or do not feel comfortable doing something, get professional help. If there is a federal disaster declaration, a telephone "hotline" will often be publicized to provide information about public, private, and voluntary agency programs to help you recover from the flood. Government disaster programs are there to help you, the taxpayer. You're paying for them; check them out. 3: Floodproof. It is very likely that your home will be flooded again someday. Floodproofing means using materials and practices that will prevent or minimize flood damage in the future. Many floodproofing techniques are inexpensive or can be easily incorporated into your rebuilding program. You can save a lot of money by floodproofing as you repair and rebuild (see Step 8).
