Development of a Distributed Hydrological Model based on MapWinGIS
A distributed hydrological model that can simulate thehydrological processes of watershed by considering bothsaturation-excess and infiltration-excess runoff mechanisms isintruduced. The model is based on MapWinGIS platform andadopts modular programming ideas, watershed features such asriver network and subbasins can be extracted automatically. In themodel, the hydrological processes of watershed are divided intoevapotranspiration,runoff gereration, overland flow, interflow,groundwater flow and river channel flow, and each process has avariety of calculation methods This model considers multiple runoffgeneration mechanisms, such as saturation-excess runoff andinfiltration-excess runoff. The calibration and test of the model areperformed in qinhuai river watershed, a basin in Jiangsu province,eastern China. The results show that the watershed featuresextracted automatically based on MapWindow GIS is reasonable,and the simulated runoff hydrograph is pretty matching theobserved values.
