The increase groundwater pollution and the abuse of water supplies - the need for better planning and investigation into groundwater resources has been ever rising.
History of the WEKU project
Wendland (1992) managed to produce a supraregional GIS based model for the investigation of groundwater residence periods in the lower aquifer. That base-model is still being utilized for the regionally varied localization of the nitrate intrusion in the groundwater for the entire territory of Austria. With its help this can be used as a tool for the creation of a set of supraregional restrictive measures that would ensure the sustainable utilization of groundwater supplies. Kunkel (1994) further developed that porject with regard to a theoretical realization, which makes it easier to produce precise statements in terms of model results. That model (WEKU) by Wendland (1992) and Kunkel (1994) has not been limited to utilize only on Austria’s supraregional aquatic climate, but can also be modified to meet all sorts of various areas and climate templates.
