Conteúdo: | Geographic Information System (GIS) provide researchers with a powerful modeling tool. This paper describes and discusses two distinctly different applications of GIS in agricultural modeling. In the first application, a GIS was interfaced with a crop growth model (EPIC-PST), a linear programming model (LPM) and a ground water flow model (MODFLOW). The objective was to study the long term impacts of agricultural management practices on the ground water levels in the Central High Plains. In the second application, a GIS has been directly linked with three mathematical simulation models -- a digital elevation model (DEM), a curve number model (CNM) and a flood hydrograph model (HEC-1). This system of models was intended as an aid tool for basin wide hydrologic studies including storm water management and the operation of flood retarding structures. EARTHONE, the GIS used in both applications, serves multiple functions including management and display of the data and multi-layer analysis.
