In KliMaWerk, integrated measures and strategies are developed to increase hydrological and ecological resilience for watercourses affected by climate change. Special consideration is given to low-flow and drying situations, alternating with heavy rainfall events. The ecological functions of the water bodies as well as competing water body uses are taken into account through the integrated consideration of an entire water body catchment area. What is new here is the holistic view of the landscape water balance, instead of a narrow focus on individual spatial elements or individual user groups.
