Assessment of sustainable groundwater resources by use of a national hydrological model

Research output: Chapter in Book/Report/Conference proceedingConference article in proceedings


To manage water resources effectively, we must first understand how much water is available and where it is located. This knowledge is acquired by undertaking a resource assessment based on the measurement and modelling of the various elements of the water cycle. To achieve a sustainable water management regime, the needs of abstractors and environment has to be balanced. This resource balance may be approached in a number of different ways, with evalution of 'non-hazard' influences on groundwater levels and low flows in rivers when abstracting groundwater aquifer systems. In the paper four sustainable yield indicators were applied in order to estimate the influences on the freshwater cycle from groundwater absttraction and in this way assess the exploitable groundwater resources for the whole country of Denmark. The result showed that the exploitable resource matches the current abstraction quite well at about 1 x 109 m3/year ~ 23 mm/year for the whole country. However, due to large regional variation in availability of resources and of abstraction, there are areas where the current abstraction constitutes a very significant overexploitation.
