A laboratory study of a kinematic wave model and Nash model is presented for a converging surface. The interdependent behavior of kinematic wave parameters is shown and based on this observation an experimental justification is given for retaining only one parameter in the kinematic wave model. It is observed that an objective function based on minimizing the sum of squares of hydrograph peak deviations is sufficiently adequate for fitting the entire hydrograph. An objective comparison of the two models demonstrates that the kinematic wave model is uniformly better than Nash model in performing hydrograph predictions on the laboratory watershed. 1975.
