In this dissertation we evaluated the potential for generating electrical energy on a smaller stream, Pendirjevka, within the Krka river basin located on the Gorjanci hillside. The estimate was made on a section between two gravel barriers. Since the hydrologic data for this section were not available, we first checked the characteristical flows using empyrical formulas and then compared them with those of an adjacent river basin, whose long-time series of average daily flows were accessible. Based on the confirmation of the two basins being similar, we determined the series of Pendirjevka's average
daily flows in the discussed period.
The next step consisted of determining the available daily flows which can be exploited for energy purposes and determining the energy characteristics of the hydroelectric power station based on the chosen installed flow of the turbine. We gradually increased the installed flow and each time calculated the produced energy and its earnings. By doing so we determined the optimum installed flow and the characteristics of a power station for which an investment is economically legitimate.
