The article analyzes the influence of operation on all structures downstream the stream on the water content and dryness in the stream. As area of interest was chosen the catchment of a small stream in the foothill region with a gauging station and several water structures built on this stream in the last century. Seven structures with the most significant impact were examined. Multiple reconnaissance of the terrain and structures were performed, in different time periods; the existing operational manuals of water...

The locality on the Hron River close to the town of Banska Bystrica (Slovakia) was selected, based on the study of effectiveness of the hydro-energetic potential of the Slovak Republic and on the engineering-geological survey, for the construction of a small hydropower plant in Salkova. In the process of the environmental impact assessment, it was required to determine the impact of the proposed hydraulic structure on the surface and groundwater level regime of the adjacent area. Therefore, the 3-D mathematical mo...

The article analyses the current state of flood protection of the urban area in the foothill region. Problems of the area were characterized through selected critical points that support the local flood origination. Of course, the flood is a random phenomenon and its behaviour depends on many other factors, such as soil saturation, vegetation cover, river bed channel current state, as well as drainage cuts, soil management, etc. For efficient design of the flood protection measures, it is necessary to have input d...

For proper construction and operation of the industrial park there was proposed and already realised a 38 groundwater extraction well system from which optimum pumping rate is required to keep the groundwater level at required elevation. To address this challenge numerical groundwater modelling system using TRIWACO simulation package has been applied. The modelling package utilises finite element method (FEM) that can handle complex aquifer parameters for running quasi three-dimensional groundwater flow model. Bas...

Occurrence of flash floods (floods from intensive short-term rainfall) increased in last few years because of weather changes, mostly on the small catchments. Affected small catchments are characteristic with lack of information about hydrologic data, mostly no gauging and precipitation station are established there (it is impossible to warn inhabitants). Besides that, in Slovakia is common that house building is very close to the stream, therefore is impossible to change somehow river routing, or change the cross...

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 goal of the contribution is to present a comprehensive and complex possibility of modelling the runoff processes for a given part of Bratislava city. The complex approach consisted of mutual integration of results of partial mathematical models пїЅ rainfall-runoff model, sewage system model, 1-D hydrodynamic modelling of open channel flow together with partially covered flows, 2-D hydrodynamic modelling of flooding the town residential area. All modelling works have been done in DTM coming from aerial photogra...

The goal of the contribution is to elaborate the analysis and prognosis of groundwater level regime using numerical modelling to show the possibility of introducing technical measures which have to mitigate the unfavourable groundwater level regime in the vicinity of the hydraulic structure. For numerical simulation purposes a mathematical model by means of finite element method has been provided in right-side alluvium of the VпїЅh River with detailed concentration on endangered village in the vicinity of the hydr...
