The aim of the project is to develop adaptation strategies for dams and reservoirs that take into account shifting precipitation regimes and their resulting discharge conditions, as well as their effects on reservoir operation and water quality. The adaptation of reservoir operation towards a dynamisation will be developed using a modelling approach, while taking into account competing uses and requirements such as water supply security, dam safety, flood protection, low flow augmentation, hydropower and recreational use, minimum environmental flow and requirements of the Water Framework Directive. The dynamics of reservoir operation will be transferred into an overall concept for the adaptation of water management plans, taking into account the competing uses and target conflicts.

Suitable indicators will be selected and further developed in order to identify any need for action at an early stage and to create a framework for action in agreement with the supervisory authority. In this framework for action the necessary individual case solutions can be worked out for each reservoir.

Cooperative partners for the project include reservoir operators (from North Rhine-Westphalia and Saxony), the municipality of Simmerath, the Landesamt für Natur, Umwelt und Verbraucherschutz Nordrhein-Westfalen (Regional Office for Nature, Environment and Consumer Protection North Rhine-Westphalia) and the district authorities of Cologne.
