Summary "Flood inundation models enable us to make hazard predictions for floodplains, mitigating increasing flood fatalities and losses. This book provides an understanding of hydraulic modelling and floodplain dynamics, with a key focus on state-of-the-art remote sensing data, and methods to estimate and communicate uncertainty. Academic researchers in the fields of hydrology, climate change, environmental science and natural hazards, and professionals and policy-makers working in flood risk mitigation, hydraulic engineering and remote sensing will find this an invaluable resource. This volume is the third in a collection of four books on flood disaster management theory and practice within the context of anthropogenic climate change. The others are: Floods in a Changing Climate: Extreme Precipitation by Ramesh Teegavarapu, Floods in a Changing Climate: Hydrological Modeling by P.P. Mujumdar and D. Nagesh Kumar and Floods in a Changing Climate: Risk Management by Slodoban Simonović"-- Provided by publisher
"Floodplains are among the most valuable ecosystems for supporting biodiversity and providing environmental services, and are also home to approximately one-sixth of the world population. As a result, flood disasters currently affect more than 100 million people a year. Flood inundation models are a valuable tool in mitigating increasing flood fatalities and losses. This book demonstrates how these models enable us to make hazard predictions for floodplains, support appropriate land-use and urban planning, and help discourage new human settlements in flood prone areas. It provides an understanding of hydraulic modelling and floodplain dynamics, with a key focus on state-of-the-art remote sensing data, and methods to estimate and communicate uncertainty.
