Geomorpho-Climatic Instantaneous Unit Hydrograph(GIUH) Convergence Model Under Geographical Information System (GIS)

摘要

Based on the theory of Geomorpho-Climatic Instantaneous Unit Hydro-graph , applying a Geographical Information System from the topography map of the study area,resulted in a hydrographic net map and all sorts of geomorphologic parameters using GIS. Aconvergence model of GIUH has been calculated. Through testing by using real examples,the results of calculations agrees with the observed data.
