Geographic Information Systems (GIS) have been found to be an excellent modeling application for groundwater systems. One such modeling application, ArcAEM, has been used in a variety of case studies and is capable of modeling head, flow, and particle tracks using the analytical element method of groundwater flow modeling. Unfortunately, the computation time of different hydrological scenarios using this suite of tools can be quite lengthy. Since multiple hypotheses are often conjectured for a particular modeled region, hydrologists often need to move between model versions to determine which one best represents the field measurements. For this reason, the ArcAEM toolbar was modified to incorporate model versioning for groundwater features, storing different parameters for features within different models. This system extends the out-of-the-box functionality of ArcSDE to track and manage model versions.
