Abstract :

In this field, flood one of the most dangers disasters for people of many countries face it and is one of the most destroying disasters among 15 known natural climatology all over the world. For example, about 196 million people in over 90 countries are exposed to danger of flood water.The increase in the population and the shortage of agricultural lands led to human population movement to the flood water plains and this intensifies the danger of flood water and its effects. But nowadays, considering the destroying effects of flood water on the human societies, structural methods of protection against flood water such as flood water bands and other methods of controlling and directing flood water, can be efficient only when the design capacity of these structures is high. But when these structures break, always a remaining risk exists. In most cases, such structures may be improper or their execution may be impossible because of environmental reasons and therefore non-structural methods are needed. The flood water warning for directing of the remaining risk is necessary and it is one of the most efficient methods of non-structural methods for flood water management.
