Hydrologic Modeling Of The Upper Suriname River Basin Using Wetspa And Arcview Gis

Journal of Spatial Hydrology

A grid-based distributed hydrological model WetSpa, compatible with ArcView Geographic Information Systems (GIS), was applied to the 7,860 km² Upper Suriname River basin. Model parameters were derived from a digital elevation model (DEM), land use and soil type map of the basin. These parameters and the observed daily meteorological data (1978-1983) were used (1) to tests the performance of the WetSpa model to a large tropical basin, (2) to simulate water balance and outflow hydrographs, (3) to identify the different flow components and (4) to study the most sensitive model parameters for the study catchment. The statistical model evaluation …
