How an estuary changed into a freshwater lake: the water management of Lake Volkerak/Zoom

On March 8, 1989, Technical Meeting 46 of the TNO Committee on Hydrological Research (CHO-TNO) was held on the theme: "Hydroecological relations in the Delta Waters of the South-West Netherlands'. The results of this meeting are published in Proceedings and Information CHO-TNO No. 41. On June 4, 1992, Technical Meeting 50 of CHO-TNO took place. During this meeting the results have been presented of an evaluation of the water management of Lake Volkerak/Zoom - a new freshwater system in the Delta. This publication contains the papers presented at this meeting, which was organized in co-operation with Rijkswaterstaat, Directorate Zeeland. These papers consider the key questions, whether water management has been able to deal with the changes in Lake Volkerak/Zoom and whether the management policy targets will be achieved.
