Study on integrated flood protection management for the Schöcklbach, Styria Optimisation of retention basins in combination with natural flood water retention on floodplains
Abstract
In recent years, Andritz as part of the city of Graz has been severely affected by floods coming from the Schöcklbach, a tributary of the Mura River (e.g. two major flood events in 2009). Due to the high settlement density and the associated substantial damage potential, the improvement of flood protection in this area is desirable. Since the run-off capacity in this river reach is limited by its cross section geometry, alternatives in reducing the negative impacts of floods are evaluated. Earlier plannings comprised the construction of two retention reservoirs in combination with linear flood protections measures in the urban area. These measures would provide a protection level for HQ50. The Styrian government aims in further improving this protection level (if possible up to HQ100). Therefore, the optimisation of the planned measures as well as the strengthening of natural flood water retention on floodplain areas is considered to improve the overall flood protection situation. Within an integrated flood risk management, this retention study aims to close knowledge gaps in regard to hydrology (unobserved and ungauged catchment) and hydraulics (efficiency of floodplain areas, optimisation of retention basins) with the aid of the FEM-method (Floodplain Evaluation Matrix).
