Application Of Desktop GIS For Decision Support In Groundwater Management

J. Furst & W. Hanusch
In this paper, a split approach to decision support systems for groundwater management is proposed. In the initial phase, a model specialist performs data acquisition, model design and calibration, using an appropriate software package. As a result, a set of carefully selected basic management scenarios is generated. Simple superposition of these will allow to approximately solve a large number of variations of a class of management alternatives. For the phase of scenario analysis and decision support, the relevant data and the results of the base scenarios are transferred to a desktop GIS (ArcView). A convenient ArcView user interface was developed to formulate a scenario, do the required overlays of the base scenarios and visualise and characterise the impacts.
