Abstract
Environmental sciences are evolving from a simple, local-scale approach toward complex multilayered, spatially explicit regional endeavours. Advances in computer simulation and high performance computing in recent years greatly extends the possibilities in this field, and changes the ways in which land management systems operate. The Datacrossing DSS is a decision support system that relies on a basin-scale groundwater model and a geographically distributed GIS to support decision makers, through a userfriendly web interface, in the field of sustainable water resources management. The portal, for the general user, exposes hydrological applications based on geochemical field data, geophysical surveys, and results of the finite element hydrological CODESA 3-D model quantifying the impact of point/nonpoint pollution. Within an experimental collaborative environment, modules have been developed to run real-time applications based on numerical solvers, run pre-and post-processing codes, and query and map results through the web browser. Our aim is to build a collaborative platform that, by introducing the computational and data-sharing advantages of a GRID infrastructure, promotes joint initiatives and encourages cooperation among interdisciplinary teams operating in the environmental sciences. To illustrate the potential of our decision support system, we present its application to a complex industrial area in Sardinia, Italy (the Portoscuso site) and a less-impacted aquifer in Morocco, province of Tetuan (the Oued aquifer).
