Sažetak
Flood development in complex flow conditions where significant influence of backwater effect is present is not straightforward from the standpoint of flood generators and selection of the design flood flow. Design principles applied for levees within the flood risk management are frequently challenged. Research focus of this paper is Sava River reach in Croatia, where high flow water regime is heavily influenced by the construction of the flood retention system. Methodology used for flood hazard assessment combined application of flow routing, flood frequency analysis and numerical model computations on analysed 4 gauging station records. In this paper design criteria for levees is determined combining information from gauging station monitoring and available data records on historical floods on Sava River reach where significant backwater effect is present. Based on hydrological events during which coincide high water flows both on Sava and Kupa River, stage-discharge curve was constructed for use in levee design analysis. Water levels are calculated using 1D numerical model HEC-RAS calibrated on gauging station recordings. Final verification of proposed methodology for levee design places emphasis on the observation of flood situations that occurred in the past in order to further the current flood management practice.
