Overview of GRM

Software
The GRM Software is available for Windows 98/2000/NT/XP.

Objectives
The purpose of GRM is to give a tool to optimise the hydrological regime in terms of the various needs by the different groundwater users of a water supply area.

Every groundwater abstraction is an antropogenic interference of the natural water system. Because of the justified claim on a sustainable water supply the management of groundwater resources is an essential task. With GRM, an objective tool is available to incorporate the different requirements of the groundwater users. There will always be an area of conflict, but the task is the sustainable use of the water available. GRM is an optimising tool, on the basis of selected assesment values (in the field of Ecology,Economy and Water Management), which makes it possible to evaluate the influence of the components on the water regime. Target is to provide values for the management of a water system as an recommendation, so that in the end all groundwater users together optain an optimum.

Groundwater tables can be "controlled" in wetlands, in agricultural areas or in aride areas. It is also possible to optimise the water supply when different raw water qualities are experienced.
