Gflow 2000, which was developed by Haitjema Software, is described as a highly efficient stepwise groundwater flow modeling system. It is based on the analytic element method and models steady state flow in a single heterogeneous aquifer using the Dupuit-Forchheimer assumption, and is particularly suitable for modeling regional horizontal flow. The free educational version of the software is available for download from the site, as well as descriptions of the analytic method, stepwise modeling, surface and groundwater interactions, interface flow, the theory of inhomogeneities, and other relevant information regarding the software. As a free resource for researchers or academics, the Web site is at least worth a read for the software's potential applicability and usefulness.
