The thesis entitled Determination of soil loss by erosion and erosion control measures proposal deals with the calculation of soil loss by erosion from watershed of Dolnodubňanský stream. First, soil erosion is described generally and possibilities of erosion control measures. Next part is focused on the calculation of erosion risks in the mentioned watershed. The calculation is done using USLE according to Wischmeier and Smith. The calculation was then performed by programs USLE2D, LS converter and ArcGIS. Erosion control measures are then propose depending on the final stage of erosion hazard. All the calculated values are shown graphically in the map outputs.

This thesis deals with the monitoring of water quality and aquatic sediments analysis in the basin of Kunratický brook. Water samples were collected at six locations during once year. The results of analysis were evaluated according to CSN 75 7221 Water quality - Classification of surface water quality and Regulation 229/2007. According to CSN 75 7221 Kunratický brook is classified as very strong polluted water. Biological consumption of oxygen, ammoniated and nitrate nitrogen meet not the conditions of environmental quality according to Regulation 229/2007. Sediment samples were collected once for whole period at 4 locations. In sediment was determine the content of metals. The results of analysis were evaluated according to Regulation 257/2009. The results were compared with limits of US EPA, specifically PEC and TEC. Sediments of pond Šeberák are full obliged. Zinc, lead and cooper are in excess of sediments of Kunratický brook. Key words: water quality, sediments quality, basin

Soil erosion vulnerability of the agricultural soils and basic hydrological characteristics were reconnoitred in Chvalkovický stream basin in Vyškov county. Preparation and the analysis of source data used for evaluation of erosion and hydrological circumstances of the basin were made in ArcGIS 10.0 in software product ArcView using the set of integrated software aplicationes ArcMap, ArcCatalog and ArcToolbox and programmes LS-converter and USLE2D. For make an assessment of soil erosion vulnerability and evaluation of situation after design of erosion control measures was used the universal equation for calculation of long-term loss of the soil caused by water erosion by Wischmeier and Smith (1978).

Thesis Tracking changes water quality in Želečský creek and small water reservoir Želeč deal with tracking water quality in Želečský creek and small water reservoir Želeč. On site will be performed reguraly measurements and water sampling, which will be found in the current state of creek and in the water tank. The measured data are compared with the period 2008 -- 2009. The measured data will be compare with relevant laws. Consequently, measures are proposed as wastewater treatment, which will help improve water quality and watershed measures to prevent pollution of water reservoirs and flow washes off the fields.

The diploma thesis is focused on evaluation of land vulnerability by water erosion in the area of Luh water stream. The area is located next to the Březník and Kuroslepy village in the Vysočina region. Part of the thesis is also the suggestion of the suitable soil protection measures based on the computed analysis. The first part of the thesis consists of the literature review of selected topic and the characteristics of the study area. The second part of the thesis consists of the methodology of the land vulnerability evaluation applied by the "Universal Soil Loss Equation" (USLE Equation) from authors Wishmeier and Smith. Individual factors of the USLE Equation and final result of the analytical process (long-term average annual soil loss) were calculated in ArcGIS software, LS converter software and USLE2D software. Databases ZABAGED(R), BPEJ and DIBAVOD were used as the input data. Subsequently the results visualization into several thematic maps and analytical evaluation (discussion) was done.

The theme of this diploma theses is project of the small water reservoir on Mačický brook in cadastral Volenice. Water reservoir is designed mainly for the accumulation function, Water reservoir can improve water flow in the catchment area behind reservoir. In the first part of this thesis is the literature searches which process the topic of the climate changes. Designed reservoir can work as a measure for mitigation one of the consequences of climate change drought. Further this section dealt with possibilities of design of all required elements for project of water reservoir. The second part is focused on the very characteristics of the selected area which are used as base for the design. The third part dealt with the design of the required individual objects for proper operation of the reservoir and their verification by using hydrotechnical calculations and flood wave transformation. Also is specified the design of the integration of the reservoir into the countryside by using riparian vegetation.

The work deals with schematization area with sewage networks in the Rainfalls-runoff model urbanized watershed modeling and changes in the Manning roughness coefficient of the pipe to the main sewer, which drains most of the wastewater. The comparison was made on two schematization basin Bohnice collector the main sewer F in the city. Prague. For the simulation program was used Mike URBAN DHI Inc. The main variable was observed outflow hydrograph on the selected sealing profile watershed and its development depending on schematization and change the Manning roughness coefficient.

This diploma Thesis deals with the drainage conditions and retention potential of the selected river basin Karlínský creek in the Vysočina Region of a total area 1 722 hectare. The goal of the Thesis is to evaluate hydrological characteristics of the watershed calculated by the DesQ-MAXQ model. The input data are gained by processing of a resource materials in ArcGIS programme. The results as potential retention, volume of runoff and peak flow are presented in the form of map outputs drew up by using ArcGIS programme. An important part of the Thesis is also literary research focused to the topic issue and the characteristic of the river basin of interest.
