    Short description of measure

    Problem to be solved: Flood protection and drought

    Goal, potential objective: Researching possibilities to manage water balance

    Developmental steps: Elevation model, discharge of precipitation, modelling of hydraulic run-off in creeks and rivers

    Instruments, implementation mechanism: Investigation of flood plain, construction of digital models for different tasks, dynamic calibration with real flood events on different annualities, computation of retention potentials, feasibility evaluation

    Area of implementation: Urban

    Responsibilities: Local environmental office

    Time horizon: Medium term

    Economic aspects: Reduction of planning costs through adjusted dimensions

    Promoters, obstacles, risks: Consideration of changes due to climate change and its consequences for precipitation and consecutive structural changes

    Side effects: Uniform fundamental dimension values also for normal management of precipitation; enforcing of laws pertaining to water and waterways

    Bridge to mitigation: Especially decentral retention potentials can also be used to manage annual water balance and can thus help to reduce the energy demand for infrastructure to provide water ressources for irrigation
