Providing 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, this work contends that a complete understanding of the hydrology of these disasters is vital for developing effective means for their prevention or mitigation. The book should be useful to faculty members and graduate students, research engineers and scientists, as well as those engaged in disaster prevention and mitigation. It should be of particular interest to the UN organizations in the assessment of their disaster prevention and mitigation programs.
