Water management in newly reclaimed land

The IJsselmeerpolders - totally reclaimed area 165,000 ha - are located on the bottom of the former Zuiderzee. Due to this fact the water management system plays a very important part. A description is given of the different aspects of the water management system in the IJsselmeerpolders. The system of the agricultural and the urban areas is described, together with the influence of the systems on the geohydrological regime. Special attention is paid to the development of the water management system during the reclamation of the former sea bottom. Finally an overview is given of the research that is going on, or has been executed related to the watermanagement.
