Abstract :

Floods are natural phenomenon that human societies have accepted it as an inevitable event but the event size and frequency of flooding is caused by several factors That is, depending on climatic conditions, natural and geographical each region changes. Annually in different parts of the world, many people's lives and properties due to flood risk falls And millions of tons of precious soil are destroyed by floods. One of the world is a flood natural disaster losses Bartryn. Statistical analysis has shown that about 70 percent of flood damage is caused by natural disaster in Iran This study estimated the a probable flood and maximum precipitation using Poldukhtar suffered minor series is action. The number 20 Heavy rainfall 24Hours over 40 millimeters The number  30 seals with more than 500 cubic meters per second was chosen discharge. Selection criteria for floods had chosen the first seal is attached to the previous flood. Thus, the interval between Two flood peaks from each other, must be at least 3 times the amount of time discharge began to reach the stage of the flood hydrograph peak flow needs. Secondly, the amount of discharge after the first flood and before the second flood in less than one third flood peak is reached first.The series detailed method to estimated the flood discharge and The maximum sustained 24-hour rainfall return periods of 2, 5, 10, 25, 50, 100 and 200 years has been And the results showed that each year, probably 99.99 percent slapped with a flow rate 606.32 cubic meters and a 24-hour precipitation amount of 43.07 millimeters Poldukhtar happening in theBasin
