The present study has been conducted to evaluate the efficiency of Clark Instantaneous Unit Hydrograph Model in regenerating flood unit hydrograph in Bazoft watershed in Chaharmahal and Bakhtiari Province. The comparative evaluation is conducted between the 2h-Unit hydographs simulated using Clark model and the one obtained from averaging the observed ones. This comparison is made with the help of statistical criteria viz. relative error, root mean square of error, coefficient of efficiency and bias. It verified high level of compatibility between two unit hydrographs using the clark model and the hydrograph obtained by averaging the observed data.
