THE STUDY OF HYDROLOGICAL REGIME MODELING USING HEC-RAS MODEL. CASE STUDY RIVER BASIN BAHLUET

This paper presents the results of a hydrological simulation using HEC-RAS model within the Bahlue. river basin. In this study, the basin was modelled from the headwaters to the Targu Frumos hydrometric station. 6 date profiles were processed between the source and Targu Frumos hydrometric station. Precipitations were measured directly at the 2 stations considered, Carjoaia and Targu Frumos. Data recorded by rainfall stations over 3 days, in May 2021, were taken into account for hydrological modelling. Values r each up to 1 75 mm/h were recorded during the rain. At the Targu Frumos station were recorded rainfall values of 12 mm/h, which proves the heterogeneity of the rain. Also, it is observed that the rain starts in Targu Frumos around 16:00, stopping around 18:00. The rain continues measured at the Carjoaia rainfall station from 18:40, with values of 175 mm/h being recorded. The data recorded at both rainfall stations shows that the river basin is subject to a variable rainfall in space and time.
