Automatic Modelling Using Hec-Ras for Steady Flow Analysis

River Bârzava and its tributaries drain an area of approximately 1202 km2 and springs from the Semenic Mountains, located at 1190 m altitude. In this study had used Hec-RAS software, which effectively simulates changes in hydraulic behavior. After importing the TIF file and creating the digital model, the geometry of the watercourse was created. Representative cross-sections for hydraulic analysis were also defined. To perform the hydrodynamic analysis of the watercourse studied, it is necessary to define the type of flow regime used in the calculation. Thus, for the chosen scenario, the steady flow regime was chosen. The results, including velocity and cross-sectional maps, provide precise information on critical parameters, allowing the identification of areas with high occurrence velocity. The study area is a sector of the River Barzava between the localities of Ghertenis and Sosdea. The results of this work can be a possible alternative for flood risk strategies and an appropriate tool for flood risk management and early warning systems.
