DiPol aims at identifying impacts and at suggesting measures to reduce adverse consequences of climatic changes for the quality of urban and coastal waters. Hence it will have a direct impact on water quality. A programme tool, (SIMACLIM) that illustrates the impacts of climate changes on water quality and which is able to evaluate consequences of potential measures to help regional and national decision-making to adapt their management to the changing climate will be developed and implemented within the DiPol project. By introducing the results into the level of European policy making, a long term impact on the Water Framework Directive and the Marine Strategy is expected.
