Large coherent groundwater aquifers refer to aquifers without any clearly separable watershed within the model area. In order to describe large heterogeneous aquifers extensive consistent locally dissolved parameter sets with spatial structure have to be developed. The groundwater budget within a regional model area interacts with several outer factors, most important of them are groundwater inflow, recharge from precipitation, surface waters or agricultural irrigation at one side, and the area exploitation, output through wells, evapotranspiration, surface run off or groundwater outflow at the other side. So besides the values for material data and boundary conditions of the geological layers a set of further data has to be derived. The parameterisation of the groundwater model was done in connection with a decision support system, containing also all non-groundwater components and thus yielding the outstanding input data. The groundwater flow model is then suitable to be extended to a transport model, including salination processes due to agricultural irrigation.
