Early View article: “Development and Integration of a Groundwater Simulation Model to an Open Geographic Information System,” by C.N. Almeida, J. Roehrig, and E. Wendland.
One thing we look for when we publish descriptions of software is the basis behind the model. This is a good example.
Abstract: “This study presents the implementation of a spatial decision support system (SDSS) named ARENA. The program has been developed based on object-oriented concepts using the Java programming language. The SDSS is made up of a groundwater simulation tool coupled to an open geographic information system (open GIS). Both the open GIS and groundwater simulation package share common spatial and nonspatial entities during the modeling process. A dedicated interface provides direct access to the GIS data without the need of external files. The finite element method is used to solve the partial differential equation that governs groundwater flow. The system implementation is presented by depicting the main classes and coupling procedures. A study case demonstrates the applicability of the simulation tool.”
