Popis: In the Netherlands waterboards are responsible for the surface water management. They try to fulfil mainly the agricultural demands by improving the drainage conditions in wet periods (by lowering the surface water levels) and sometimes by raising the surface water levels in dry periods during the growing season. This type of operation is based on practical experience. A more systematic approach is presented that yields better results. This approach prescribes the way to react upon changes in groundwater levels and soil water status. Nature reserves are influenced by the operation of the surface water system in neighbouring agricultural areas. The possible mutual influence is illustrated with an integrated model for the regional groundwater flow, the flow of water in the unsaturated zone and the surface water system. On basis of the results of three case studies, it is concluded that surface water management is an effective means to improve the hydrological conditions in both agriultural areas and nature reserves. To realize this improvement a systematic approach using simulation models, is very helpful.
