Abstract

Flood means a sudden overflow of water due to hydro-climatic and hydrological conditions, severe rains, and damages to dams in different areas of the earth.
Evidence suggests that life and financial losses caused by flood are more than other natural disasters. Today the estimation of maximum flood and its prediction before occurrence are among the important issues discussed in hydrology; nevertheless, with increasing population growth and development of industry and the subsequent occupation of the lands adjacent to rivers, the losses caused by flood have not only not diminished, but are constantly increasing.
What is certain is that flood is caused by rain, but studies show that there is no linear and direct relationship between these two factors. Climate, natural and geographical conditions of a region are among the main factors that contribute to the disruption of this relationship.
