In the designing water reservoirs, information on flood control it’s necessary to make the right technical decisions related to the safe use of reservoirs, human life and the natural environment in the areas below the reservoirs.The hydrological data of a given river profile (stages and discharges) is important for the planning, hydraulic modeling of the reservoir and its exploitation. In the last years of the twentieth and twenty-first century in Central Europe, many floods of different intensity and extent have occurred on the Odra River and its tributaries. Therefore, the increasing extreme natural phenomena, like a violent floods and long droughts, mean that the importance of hydrotechnical constructions increases. One of the planned investments, which is to minimize the effects of the flood by collecting a flood wave on the Osobłoga River is the dry dam named Racławice Śląskie. According to Polish law, model researches are required for the 1st and 2nd class of hydrotechnical constructions. Considering research models, not only physical models are used, but also hydroinformatic programs for the numeric model, like HEC-RAS. These programs enable modeling based on hydrometric measurements of rivers. The aim of the work is to model the discharges using the HEC-RAS program after analysis of the hydrological data. Analyzes and modeling were made of the planned reservoir – the dry dam across the Osobłoga River, Racławice Śląskie profil in the Opolskie Province, in Poland.
