The article analyzes the need of a suitable velocity field creation in the cross section profile of the fish pass, which would generate velocity variability for the occurring ichthyofauna with different swimming abilities. In this way, is not only the condition for the maximum vertical velocity fulfilled, but also parts of the profile with slow-flowing water in the bank zone are formed. There are also others recommendations as top width of the water level, doped discharge or recommended longitudinal slope of the f...

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...

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...
