ISSUES AND APPROACHES TO COUPLING GIS TO AN IRRIGATION

Geographic Information Systems (GIS) is increasingly being used in water resources primarily because of its ability to store, analyze and display spatial data. There are several possible approaches to coupling GIS with simulation models, depending on the objective, availability of data and resources, and the skill of the modeler.Get price

Calibration of the Hydrological Simulation Program Fortran

During calibration, the GIS data were used to establish realistic starting values for the surface and subsurface zone parameters LZSN, UZSN, COVER, and INFILT and physically reasonable ratios of these parameters among watersheds were preserved during calibration with the ratios based on the known properties of the subwatersheds determined using GIS. This calibration procedure produced very satisfactory results; the percentage difference between the simulated and the measured yearly dischargeGet price
