About this book
An up-to-date text on the simulation of flood risk in both rural and urban areas, this book begins by presenting the main concepts related to one-dimensional flood propagation. Detailed mathematical models that place particular emphasis on numerical modelling are featured. There are also sections on practical aspects in river flood routing problems, parameter identification in I-D flood routing including optimising techniques with applications, and the routing of dam-break waves with a brief description of historical dam failures and their main causes. The second part of the book is devoted to urban floods with hydrological and hydrodynamic modelling. One- and two-dimensional mathematical models with practical applications in urban basins are included. Flood Risk Simulation will be of interest to postgraduate students, researchers and professionals involved in this area of water resource management.
