Lazy Bledowskie well field located in the area of the Upper Silesia, was established in 1959. It consisted of max. 22 wells abstracting water from the Triassic carbonate aquifer (Olkusz-Zawiercie major aquifer). This aquifer is additionally heavily drained by Zn-Pb ore mines. Due to the decreasing demand for water and the deterioration of its quality, wells were gradually excluded from operation and liquidated. Currently, only 2 wells are exploited, pumping approx. 11500 m3 /d. As a result of the overlapping impac...

This research paper seeks to study the phreatic groundwater body from the Buz?u river alluvial fan. This goal is reached by creating a numerical model associated to a previously created conceptual model. The conceptual model was realized in three stages. Initially, a spatial schematization of the hydrostructure was created using the lithology collected while executing the hydrogeological boreholes. The second step consisted in studying the variation of the hydrogeological parameters in the hydrostructure. The para...

The precipitation surplus of the year 2009 has caused regional increase of the ground water table in the whole lowland region of Slovak Republic. The contribution deals with the analysis and the evaluation of the potential impact of treatment carried out through the Trn?vka River on the groundwater level regime in the adjacent area in the county town of Trnava. The aim of the article is to refute the false presumption of incorrect technical solution of Trn?vka stream training namely on the basis of similarity of t...

The wind energy is a modern and efficient solution that uses the air flow through wind turbines to mechanically power generators for electric power production, being an alternative to burning fossil fuels. Wind power is renewable, widely distributed, produces no greenhouse gas emissions, consumes no water and uses small land areas. A wind turbine converts the kinetic energy of the wind into electrical energy. The electrical power generator and the steel upper structure of a wind turbine are equipments where were i...

One of the most common geotechnical risk induced by earthquakes is liquefaction phenomena, which it has been responsible for building damages that directly influenced population and economy. The growing recognition of importance of geotechnical site conditions in earthquake-prone areas has been generated by concern about liquefaction observed in strong seismic motions that occurred during 20th century. The paper aims to substantiate the necessity of a rational assessment of uncertainties and risks related to seism...

The technology of Permeable Reactive Barriers in recent years is one of the most frequently developed methods of protecting the soil and water environment from pollution. These are zones filled with reactive material, in which during the flow of contaminated groundwater, contaminants are immobilized and/or their concentration is reduced to the limit values. Currently, there are relatively few deep installations compared to shallow systems (e.g. <10 m), resulting mainly from higher costs and technical difficulties ...

The article is concerned with underground and pit water hydrodynamic regime during Shumicha deposit Kizel coal basin storage underground treatment and after closure and inundation of self-titled mine. On the area of the deposit a heavy fissured-karst water level of Visean and Serpukhov stages carbonate deposits, fissured-stratal water complex of Visean stage coal-bearing series and fissured-stratal and fissured-karst water complex of Tourian stage of the lower carboniferous are developed. In vivo rivers Kosva and ...
