Water management is one of the few areas in which a large part of projects have a practical component. Most of these projects are no-regrets options as well, since the cost of floods has been increasing because of the accumulation of assets in high-risk areas. In addition, a study commissioned by the BMFLUW and the entities responsible for water management in the Lander (BMLFUW, 2010) has shown that for the period up to 2050 there is no need for immediate practical measures for climate change adaptation. For example, floods were projected to vary between -4% and 10% relative to scenarios with no climate change.
