The European pilot on fresh water in DROP will focus on decreasing water quality in water reservoirs in NWE as a result of drought. Institution d Aménagement de la Vilaine and Wasserverband Eifel-Rur will join forces and combine their knowledge to develop and test new measures on drought adaptation for NWE regions dealing with threatened water quality issues of drinking water reservoirs. Focus is on NWE coastal regions and large inland-damcontrolled reservoirs. Low flow conditions and high temperatures in combination with the existing too high nutrient concentrations will lead to more algae bloom (cyanobacteria). More insight is needed on the effect of climate change (CC) on large water reservoirs. Also, different ideas (physical barriers or inland adaptations in the water system) to combat salt intrusion in water reservoirs in coastal areas are not sufficiently tested in practice.
European regions depend on different water sources for the production of drinking water. Climate change and changing weather conditions affect both sources of drinking water. In general in NWE regions there is a conflict of water allocation for agricultural, nature, industry or drinking water purposes (multi-user). This decision conflict is worsened by climate change and lower availability of water in a region. Following these problems, Wasserverband Eifel-Rur will design and evaluate a study on CC effects for large reservoir system and draft a management plan for multi-user water reservoirs; partner Institution d Aménagement de la Vilaine will make a feasibility study regarding changes to larger NWE sea-river locks with the aim to diminish salt-water intrusion into drinking water reservoirs. The aim is to jointly test, evaluate and develop measures applicable to other NWE areas. This EU pilot is therefore a combined effort of the NWE practice regional partners of DROP in FR and DE for the common benefit of NWE.
