Interactive Groundwater
A sophisticated combined research and educational software environment for unified deterministic and stochastic groundwater modeling. Based on a set of new efficient and robust computational algorithms, the software allows simulating complex flow and transport in aquifers subject to both systematic and "randomly" varying stresses and geological and chemical heterogeneity. Interactive Groundwater was developed at Portland State University. The program was modified and extended at Michigan State University and can be found in all of the DECS public PC labs.
Interactive Groundwater is available to anyone who wants to use it and has access to the DECS labs.
