Abstract:

One of the most important mankind problem are floods which always attracts the hydrologigists and hydraulic structural designers, attention. The necessity of flood control , is recognizing of the frequency and the intensity of phenomenon and its estimation and general announcement for reducing of strural damage and loss of life. The reations between the effective for this phenomenon . are non linear and their nanlyzing are so complicated. In this investigation for estimate the maximum mean daily discharge of catchment , s area of hallil River, located in city of Jiroft , Kerman Province, the author used amathematical calibration. After providing the statistics of the maximum mean daily discharg of hydrometric stations in the mentioned catchment , s area, among the accessible statistics years, 22 random years were choused and the frequency analyzing was performwd on the flood data , and finally calibration with the use of multiple regression method among the discharge of hydrometric stations of area , s upstream and input discharge of reservoir of the concrete dem show that there is a fine regression among the hydrometric station with the probability of more than 99%. With the use of this method there is the possibility of flood forecasting and according to it general perannouncement in downstream of the Halill River.
