- Abstract: The paper discusses an integrated development scheme of the future HPP Brežice reservoir area. The primary goal of the development is to establish a gravel pit, which would furnish material for the construction of the Lower Sava HPP chain, as the gravel found in the area is well suited for concrete manufacture and embankment construction. Later, the gravel pit could be redeveloped and filled with water to be used as an additional reservoir to the HPP Brežice reservoir, which would significantly improve the siting of the plant by using the area for tourist and recreational purposes. These include the creation of a kayaking trail and the development of forested peninsulas, walking trails, wetlands and other tourist and recreational sites. Besides the development scheme proposal, the study includes estimates on the volume of material extracted from the gravel pit, flow regime in the reservoir during extreme weather changes, and different hydraulic solutions of flow control, along with the calculations. During the construction of the Lower Sava HPP chain, the problem of migration of aquatic organisms impeded by the dams became evident. Fishways are a feasible solution; however, in Slovenia they are still not properly implemented, and they also mean power loss for the HPPs. The paper represents an alternative solution of the fish passage as part of the integrated development of the HPP Brežice area, along with the benefit of energy saving.
