Mathematical modelling and numerical analysis of hydraulic system behaviour. A case study with application in HEC-RAS

The paper presents an analysis of floods within the Bahlueţ watershed. The city of Targu Frumos and its surroundings have suffered floods over the years causing significant damage. This study aims to map flooding in the area analysed, using the HEC-RAS hydraulic program. Results were obtained for 1%, 5%, 10%, 20% flood recurrence scenarios over a period of time with heavy rainfall. The results show that flooding occurred in all simulated events. The city of Targu Frumos was flooded when flood events with 1% and 5% probability were simulated. Based on the results obtained, predictions can be made regarding the extent of flooding in order to take additional measures for its prevention and control.
