A suite of new simulation tools have been developed in the version 2.0 of the Department of Defense Groundwater Modeling System (GMS). These add considerable complexity to the GMS which has necessitated the development of a new approach to handling human interaction with GMS. As a result, a new conceptual model approach has been developed for defining groundwater models in the pre-processor. Once a conceptual model is constructed, both finite-element and finite-difference numerical models can be generated automatically. The development seeks to drastically increase modeling efficiency and eliminate much of the tedium involved in data entry. Additionally, several different types of numerical models can be developed from a single application to check their results and their applicability to the problem.
