Determining logical model for estimating of maximum flood in cachments lacking data in the east and south east of the Khuzistan plain

In catchment areas which lack data for the calculation of predicted maximum flow rate of flood, one of the methmethods used is the local (Regional) analysis method. In the paper in addition to reviewing emprical avidence and historical research carrid out in this regards, taking to accont the number of measuring station and the frequency of measurements an attempt was made to create a logical relationship between both. After performing the required reviwe, 1 I stations were selected and their data reconstructed. Following this stage a correlation coefficient between area and floods with various return periods, a relationship for area / return period was established which was then used to determine the maximum Flood flow rate in the study area with a 99% reliability factor up to catchments with a total area of 10000 square Kilometer.
