Vyhodnocení ohroženosti pozemků vodní erozí ve vybraném území

Kramář, Radim January 2017 (has links)
The diploma thesis is focused on the evaluation of vulnerability of land to water erosion in the sub-basin of the river Bystřice with the hydrological order number 4-15-01-0402-0-00. The work contains research dealing with soil erosion and erosion protection. Part of the thesis describes the basin of interest on the basis of a site survey and available literature. The principle of erosion risk evaluation is calculation of the universal USLE Wischmeier-Smith equation factors and the determination of the average long-term loss of soil caused by water erosion. Partial analyzes are performed using GIS tools and LS converter 1.0 and Usle2D programs. Appropriate anti-erosion measures are proposed if necessary. The measures are based on the results of the evaluation corresponding to the conditions and possibilities of the area of interest. Part of the thesis contains mapping documentation created by the ArcGIS program.

Studie revitalizace vybraného úseku Anšovského potoka, cca km 5,1 - 6,8

Moučková, Andrea January 2017 (has links)
This master thesis focuses on the study of revitalization of a selected part of the Anšovský potok. It summarizes the knowledge and options of revitalization, the actual state of the water flow, its vegetation and its limits and other natural conditions of the studied area. The final draft is based on these information, financial and areal circumstances of the village Šanov, that requested this study, and limiting factors of the studied area (irrigation system). The draft of revitalization is largely solved by slopes form of riparian edges, sometimes these forms are completed by small wooden damming in watercourse or extension of stream bed. These forms of watercourse should improve retention of water and ecological stability in studied area. The thesis forms full featured basic revitalization plan of the Anšovský potok for the village Šanov.

Studie návrhu malých vodních nádrží v k.ú. Držková, na lokalitě II.

Synakievicz, Petr January 2017 (has links)
This diploma thesis is focused on the study of small water reservoir in Držková. Projekted small water reservoir should withold water in landscape, improve biodiversity and serve as aesthetic landscape component. Basis for this study is colection of information about geology, soil condition, hydrology, climate, flora, fauna, anthropogenic impacts and historical use of area. Part of this thesis is also analysis of soil samples. Project of small water reservoir was processed with respect of functional and aesthetical views acording to norm ČSN 75 2410 Small water reservoir.

Stanovení pracovního rozsahu a účinnosti vodního trkače / Determination of the working range and efficiency of the water hammer pump

Růžička, Jakub January 2019 (has links)
This thesis focuses on setting the range and efficiency of a water ram pump through experimental measurements in a laboratory. The measurements were carried out on three different constructions of water ram pump, each of the designed and assembled by the author of this thesis himself, to find out whether the weight on the pulsating valve has an influence on the water ram pump efficiency. Further on this thesis aims at the comparison of up to now methods of water transport arrangement used at a summer camp and the usage of the water ram pump and its advantages. The principal of water ram pump originates in hydraulic impact that is being precisely described in a great detail as well. On of the chapters even includes the placement manual for the water ram pump and its overall assembly and connexion. Because the presence of floating debris is inevitable, this thesis also deals with the possibility to solve the incoming water impurities by adding an inflow gating to prevent such problem. This inflow gating has only been designed in a Flow 3D programme to introduce the idea and functions.

Návrh projektu využití historických vodních děl v cestovním ruchu CHKO Blanský les / The proposal of project utilizing historical water constructions in tourism of Blanský les

ŠŮNOVÁ, Monika January 2014 (has links)
This thesis is dedicated to the historic waterworks in Blanský forest. The main goal of this work is the proposal to use the historic water works in the tourism industry. In the theoretical part defines the concepts associated with the field of tourism, historic waterworks, management and marketing. In the practical part are selected three most important historic water works and their designed for use in tourism. Option utilization is calculated using managerial decision-making process and Saaty method. On the basis of the calculations are in the last part of the thesis proposed appropriate solutions.

Nákladní lodní doprava na Labi v ČR / Cargo inland waterway transport on the Elbe river in the Czech republic

Chrustová, Kateřina January 2008 (has links)
The thesis attends to cargo inland waterway transport on the river Elbe in the Czech republic. The target is to analyse its progress, function and place in national and international transport. The thesis shows actual problems that occur in inland waterway transport. The main problem is the bottleneck at the Czech - German border which should be solved by building-up of the weir in Děčín. But this is not acceptable for environmentalists. The target as well is to quote reasons why to built-up the weir which is important for the development of inland waterway transport.

Obnova a rekonstrukce malé vodní nádrže / Renovation and reconstruction of small water reservoir

Pavlík, Tomáš January 2018 (has links)
This diploma thesis deals with analysis of small water reservoirs and their water management. The work is divided into two parts. The first part contains research and the second one is dedicated to the project of small water reservoir. The research describes the basic division of small water reservoir and their construction and technical equipage. The knowledge that has been found is applied in the project. The project describes the renovation of small water reservoir Kančí obora and pool, in k.ú Nové Bránice and Moravský Krumlov.

Návrh protierozních a protipovodňových opatření v k. ú. Palkovice / Design of erosion and flood control measures in the cadastral area of Palkovice

Ujházy, Adriana January 2020 (has links)
This diploma thesis deals with design of soil erosion control measures and flood control measures in the cadastral area of Palkovice. The request for construction came from the village Palkovice. It sits at the foothills of Beskydy with a very sloping terrain. In addition, there are larger soil complexes without any erosion control measures, which leads to degradation and reduction of soil yields. The introduction summarizes desired objectives. Then thesis deals with the description and analysis of the current state of the village and its solution. The solution of technical measures is depicted in the situation and elaborated in more detail. The drawings are enclosed in attachment. The conclusion summarizes the content of the work, achieved goals and benefits.
