Some Advances in Geomorphologic Instantaneous Unit Hydrograph Theory

It is interesting to derive the watershed hydrology respond based on geomorphology and topography parameters of the watershed.? In this paper, the approaches of the geomorphologic instantaneous unit hydrograph obtained according to the Horton-Strahler's odering system and the random network model are reviewed, and the geomorphoclimatic instantaneous unit hydrograph is also introduced.
