Opis:: Considering limited capabilities of obtaining energy in a traditional way from coal combustion and the requirements of the European Union, other alternative Energy sources should be sought. They have been increasingly used by business entities and individual investors and are designed to provide financial profits, which will be ensured only with correct operation of the energy system. One of the examples of alternative energy sources application is the construction of small hydropower plants, where the efficiency of all elements included is of great importance. Article analyses of financial losses incurred by owners of power plants when the energy system lacks 100% capacity of the inlet channel. Material that accumulates on SHP trash racks might be analysed in two ways: biologically (these are screenings – as in wastewater treatment plants) and hydraulically.

Opis:: Hydropower is one of the renewable energy sources. Hydropower plants generate electricity using the kinetic energy of flowing water. Although hydroelectric power plants are not as prominent as solar or wind farms, it should be noted that they generate the most significant amount of the power. They are also the most technically advanced projects. Power plants are built with different technical parameters of turbines, different sizes of dams or weirs and different ways of exploiting the energy of flowing water. A common feature, however, is the significant impact of hydroelectric power plants on the functioning of adjacent regions. The paper divides this impact into economic and local development, landscape, and ecological functions, emphasizing the interaction of these influences. The paper discusses the hydromorphological changes taking place in the immediate vicinity of the structure, as a consequence of channel development. The processes of aggradation and degradation of the channel are the answer to hydrodynamic equilibrium loss. These hydrodynamic processes are associated with the subsequent ecological response of the habitat. The most important of these include the dynamic equilibrium loss by the river and the subsequent morphological parameters striving to restore it according to Lane’s relation, known as the most important principle in the fluvial morphology science. The impact of the hydropower plant on the fluvial environment results, first of all, from a significant environmental impact of the damming of the river itself. If the structure is correctly designed, maintained, and operated, it allows controlling the water conditions upstream and downstream with simultaneous energy production. Due to several geometric, hydraulic, and granulometric changes, and further, the resultant economic, landscape, and natural changes that significantly affect the operation of a region, these should be considered as early as the design stage and should be an integral part of any hydroelectric project.

Opis:: This paper contains an analysis of conditions for erecting small hydroelectric power plants on the selected river in Lublin Region. The analysis covers technical options of the location of the facilities and their energy potential split into theoretical and technical potential. In addition, it refers to the most important legislative acts governing water management, including environmental protection. According to the analysis, the technical potential of small hydroelectric power plants on the river Bystrzyca Północna is about 125.5 kW. Energy production capacity is limited by both hydrological conditions and the necessity to adapt to regulatory framework concerning nature and environment protection, superior functions of watercourses and their situation in agricultural land.

Tytuł:: Gospodarczo-społeczne znaczenie zbiorników zaporowych – studium kaskady Soły
Economic and social importance of dam reservoirs – a study of the Soła River cascade

Opis:: W artykule przedstawiono funkcje zbiorników zaporowych pod kątem przydatności gospodarczo-społecznej. Jako przykład wybrano zbiorniki trójstopniowej kaskady rzeki Soły (Tresna, Porąbka, Czaniec), która znajduje się w południowej części województwa śląskiego. Kaskada jest zintegrowanym systemem retencyjnym, ale poszczególne zbiorniki pełną różne funkcje. Omówiono rolę zbiorników w ochronie przeciwpowodziowej (Tresna, Porąbka), w zaopatrzeniu w wodę pitną (Czaniec), w produkcji energii elektrycznej (Porąbka), w rekreacji (Porąbka, Tresna), w dostarczaniu kruszywa skalnego (Tresna). Wykazano duże znaczenie kaskady dla rozwoju gospodarczego regionu. W zakończeniu dyskutowano na temat kontrowersji wokół budowy i użytkowania zbiorników zaporowych.
The paper is devoted to the functions of dam reservoirs in terms of their socioeconomic usefulness. Three dam reservoirs of the Soła cascade were chosen (Tresna, Porąbka, Czaniec) as the example that are located in the southern part of Silesian Provence. The cascade is an integrated retention system, but particular reservoirs have different functions. The role of reservoirs in flood protection (Tresna, Porąbka), drinking water supply (Czaniec), electricity production (Porąbka/Porąbka-Żar), recreation (Porąbka, Tresna), supply of rock aggregate (Tresna) was depicted as well. The high importance of the cascade for economic development of the region was demonstrated. Finally, the controversies about the construction and utility of dam reservoirs were discussed.
