This book provides a comprehensive treatment of hydrologic aspects of a range of natural disasters, encompassing climatic disasters, disasters on the land surface, geologic disasters, and land-ocean interaction. The chapters contained in the book are written by leading scientists from around the world, who have long been at the forefront of research in the area of disaster modeling. A complete understanding of the hydrology of these disasters is vital for developing effective means for their prevention or mitigation. The book will be useful to faculty members and graduate students, research engineers and scientists, as well as those engaged in disaster prevention and mitigation. It will be of special value to the UN organizations in the assessment of their disaster prevention and mitigation programs.
