AB: Groundwater modeling employs spatially distributed data in the construction of models as well as in the presentation of the models to vested interests and decision makers. Numerous commercial groundwater modeling interfaces have attempted a GIS like integration within the modeling system, with some what limited success. We will show a complete modeling development-execution-result analysis procedure which is fully rooted in a GIS environment. All model setup/input as well as results are in a GIS, thus easing access and applicability. A key aspect of the process is that the resulting model is independent of the modeling code. The procedure utilizes spatially distributed information on soil type, climate and land use to develop maps and time series for recharge. At the same time a geological editor integrated in a GIS interface is used to develop a geological model. Calibration information is also placed in the GIS. Information regarding surface water bodies, drainage, and so on is translated to the model framework within the GIS. Geospatial queries and SQL programming are used to translate these to a modeling grid. The GIS is utilized in developing input to and processing results from particle tracking modeling for well fields and critical river reaches. Maps of for example ground water age, which formations contribute to the flow system, and degree of utilization (sustainability) are easily available. Furthermore, as the results are integrated in a GIS this improves analyses as well as capabilities to communicate results to vested interests and decision makers.
