Flood impact assessment using hydraulic modelling: A case study from Stonavka and Olse river confluence area

Original language description

Floods are one of the three most common natural disasters. Floods threaten human life and property worldwide. The increase in number of human life and material losses indicates the difficulties with flood prevention and reduction of human losses respectively suffering and damage to natural and built environments. Science and technology play an important role in this complex problem. Hydrodynamic modelling is the most used simulation and modelling tool of floods. The main aim of this paper is to assess the flood impact using modelling tools in the Stonavka and Olse river confluence study area, which is prone to periodic flood occurrences. In the study was used digital elevation model created by LIDAR survey with resolution 0.2 m and detailed cross section, because hydrodynamic modelling requires precise data. It has been reconstructed the September 2007 flood, whose flooded area and heights of water surface has been measured. 1D HEC-RAS software has been chosen for modelling unsteady flow (dynamic wave approximation) of 2007 flood time period and steady flow (energy equation method) of Q5 and Q100 peak discharges. It has been evaluated the water surface height, velocity of flood for selected cross sections and inundated area. Land cover layer has been used to calculate the percentage of types of flooded area (meadows, forest, etc.) assessment of land use suitability and potential impacts of flood. The hydrodynamic modelling results comparison with empirical data showed that the chosen model is convenient to proper flood modelling. Most of the flooded land use types are non-irrigated arable land, dump sites and forest. But urban fabric is located in inundation area in some cases too.
