| Abstract: | According to a general theory of conceptual watershed geomorphic concentration model, using the conceptual element of linear dynamic wave reach to simulate the concentration action of each ordering_unit channel, a geomorphic instantaneous unit hydrograph model is developed based on linear dynamic wave. The instantaneous unit hydrograph of three_order basin is derived; and the effect of the model parameters on the instantaneous unit hydrograph is analyzed. The constraint conditions of the parameters and the method for solving the parameters are discussed. An example about Nanyan basin is attached. |
