A water management plan (WWP) is a concept for the management and dimensioning of a dam on a body of water ( dams ) or for a river basin district . The various goals of water management in the use of water bodies and in the water balance are thus coordinated. Since the end of the 20th century, the main goal of sustainable and environmentally friendly water use has been pursued.

In the water management plan z. For example, the storage spaces sized that for the economic use of the river and the necessary flood protection are needed. It serves to ensure that there is always a sufficient amount of good quality water available as drinking water or process water . At the same time, the aim is to always have enough free storage space for flood protection. Therefore, certain highest and lowest congestion destinations must be adhered to. Another goal is the dimensioning of the overflow capacity of the barrier structure of a dam during high water and thus the safety of the structure and the downstream .

The water usage rights should also be reconciled or are granted according to the WWP, for example the right to impound a body of water, to generate hydropower , to withdraw water, to use shipping, to increase the low water level to guarantee a minimum runoff, etc. The water management plan contains regulations such as the outflow with the operating facilities ( bottom outlets ) is to be controlled depending on the inflows and the withdrawal requirement.

Since most bodies of water and dams are in public (state) ownership and the supply of water and flood protection are of public interest, the management of bodies of water is a state task and therefore a water management plan must be approved by the state, for example in the form of the regional councils become. The water management plans are mostly drawn up by the water boards that also operate the dams.

Closer to the water management plan is found in the DIN 19700 or Directive 2000/60 / EC (Water Framework Directive) .

An example of a water management plan is SAGE (France) . In Germany, water management planning is based on Sections 82 ff. Of the Water Management Act .
