Abstract Reliability analysis was applied to evaluate the uncertainty of SCS method in estimation of peak discharge and runoff volume at various return periods if the SCS input parameters (CN and Tlag) were considered as random variables in arid regions. The study main conclusions are: 1) The SCS method should be used with caution when the rainfall coefficient of variation is smaller than 0.5. 2) Design of water structures should consider the peak discharge and runoff volume in arid regions. 3) Application of SCS method in arid regions is more reliable when the return period is small |
