Linear Channel and Its Effect on the Geomorphologic IUH (Instantaneous Unit Hydrograph)

摘要

To more accurately determine the factors influencing run off from a drainage basin, the Instantaneous Unit Hydrograph (IUH) is derived as a function of the basin's geomorphological and physiographic characteristics. Inherent in the basin IUH is the response of the individual channels composing the basin. The response of the individual channels is derived by solving the continuity and momentum equations for the boundary conditions defined by the IUH. The effects of both upstream and lateral inflow to the channels are taken into account in the derivation of the basin's IUH.
