Study on WGIUH by means of geomorphologic and hydrodynamic dispersion

The geomorphologic dispersion is described by the width function,the hydrodynamic dispersion is described by the channel response function,and a formula of the watershed geomorphology instantaneous unit hydrograph (WGIUH) can be obtained.The geomorphologic parameters in the formula of WGIUH is determined by the digital elevation model (DEM) of watershed.The example is given in order to test and verify the new method.
