The efficiency of flooding depends upon 6 numerous criteria: flood strength, amplitude, frequency, flow time, changes in plan and 7 river geometry, etc. In this research, three statistical models such as the frequency ratio, 8 Shannon's entropy, and weight of evidence have been used to identify flood susceptibility 9 regions in the Kopai River Basin.
