UPPER STREAM OF THE RIVER SANA – JUSTIFICATION OF BUILDING HYDRO POWER PLANTS WITH RESPECTIVE ACCUMULATIONS

The river basins in the territory of the Republic of Srpska are a part of the basins stretching across the entity borderline, even across the borders of Bosnia and Herzegovina on the whole. Exploiting and managing waters in upper and middle streams respectively may have significant impact on the conditions of exploiting waters in lower sections of basins as well. Processes that are dominant in the former sections are directly reflected on those taking place in the latter ones. Given the position of basins in the territory of Bosnia and Herzegovina and the Republic of Srpska respectively, there is a pronounced necessity for researching into the matter, in accordance with current trends in the world and our geographic area. The existing engineering-geological, hydrological, and geomorphological data on the basin of the upper stream of the Sana show that this area is suitable in terms of building hydro power plants with respective accumulations. A hydro power plant, or multiple plants, in the upper stream of the Sana, featuring poly-functional contents, is going to contribute to the economic development of the area, all with the preservation and enrichment of the environment at the same time.
