VRÁBEL Marek: The Impact Assessment of the Inflow to the Fish Passon the Electricity Production of the SHPP Slovak University of Technology, Faculty of Civil Engineering, Department of Hydraulic Engineering Bachelor thesis, 31 pages, 7 appendixes The primary goal of the bachelor thesis is to develop basic hydraulic calculations for the small hydropower plant Podtureň, Liptovský Ján on the Váh River. The thesis is divided into the four chapters. The first chapter is introduction about energy generating from water and utilization in foreign countries. The second chapter talks about classification of the hydropower plants and about short history of hydropower plants in Slovakia. The third chapter is describing area of the SHPP, planned objects and hydrological condition of the stream. The fourth chapter solves water level regimes and their comparisons by the suggested modifications of the river bed, design of the turbines number, diagrams and tables for the electricity production calculations. At the end is also conclusion, which summarizes all the numbers and calculations.
