Analysis of Retention Potentials in Urban Areas

"Analysis of Retention Potentials in Urban Areas" investigates the possibilities to manage the water balance. This measure precedes and is closely related to the measure Flood Area Protection.

    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
