This master´s thesis presents the project solution for the regulation of the lower course of the Gerovčica river, from the spring to the place Zamost. The success of solving engineering tasks is related to the degree of understanding of the nature of the river. The main purpose of the implementation of the regulation is to protect the area from erosion and flooding and to protect the environment. The fall of the bottom of the natural riverbed of Gerovčica is great and the level of the regulated channel is set to follow that line as closely as possible. Due to the steep terrain on the regulated section, the construction of stairs with a waterfall is planned. A hydraulic calculation was carried out in order to dimension the cross-sections and select the material for the implementation of watercourses regulation. Since there are no measurements on the watercourse, the cross-sections are dimensioned for the maximum flow ever recorded, which is 30,00 m3/s. Construction and stability calculations were carried out for the planned regulatory buildings. The value of the investment was estimated using the cost statements. All graphic attachments of the project solution were created in the AutoCAD program.
