Rhine-Meuse Delta Decision

The Rhine-Meuse delta is the transition area between the rivers and the sea: the area of the large rivers, Rhine Estuary-Drechtsteden and the South-western delta. The basis of water safety in the Rhine-Meuse Delta consists of four elements: the sandy coastal base, dikes, storm-surge barriers and sufficient room for the river. This turns out to be a sound basis for the future as well. The issues can be tackled properly and in good time using sophisticated, customised spatial planning and adaptive delta management.

Rhine-Meuse Delta Decision

The Rhine-Meuse delta is the transition area between the rivers and the sea: the area of the large rivers, Rhine Estuary-Drechtsteden and the South-western delta. The basis of water safety in the Rhine-Meuse Delta consists of four elements: the sandy coastal base, dikes, storm-surge barriers and sufficient room for the river. This turns out to be a sound basis for the future as well. The issues can be tackled properly and in good time using sophisticated, customised spatial planning and adaptive delta management.

The distribution of water from the Rhine across the Waal, Lower Rhine-Lek and IJssel is of great importance to water safety in the region. An element in the proposed decision on the Rhine-Meuse delta is therefore that existing agreements on the distribution of discharges remain in place until 2050. In the years ahead, a decision will be made as to whether changing the distribution of discharges will remain an open option for the period after 2050. The proposed decision also states that no river water storage will take place in the Grevelingen.

The Delta Programme proposes not to close off the Nieuwe Waterweg with a dam and not to build any new flood defences in the river estuaries. Rather, the proposal is, after 2070, when the Maeslant barrier is due to be replaced, to build a new closeable storm surge barrier. The Ministry of Infrastructure and the Environment is going to investigate how the Maeslant barrier can make a better contribution to safety up until 2070.
