The geo-referenced regional exposure assessment tool for European rivers (GREAT-ER) constitutes a powerful software tool for modelling the fate and behaviour of chemical substances in surface waters. It combines a geographic information system (GIS) with chemical models for calculating and modelling spatially explicit substance concentrations. It was originally designed for the prediction of spatially explicit exposure concentrations of typical down-the-drain chemicals in whole river basins.
The latest version – GREAT-ER 4.1 – provides numerous features for graphical output and analysis of simulation results as well as a menu-driven scenario definition dialog. The latter can be used for a priori evaluation of reduction measures by comparison of simulation results from management scenarios with the status quo represented by respective reference scenarios.
GREAT-ER 4.1 is now available as a blueprint for free download.
