Fluctuations in the groundwater level in the montane peat bog Rokytka
Lencová, Kateřina ; Šobr, Miroslav (advisor) ; Doležal, Tomáš (referee)
Peatbogs are globally widespread ecosystems that have a major influence on the hydrological conditions of watersheds. Of particular importance are mountain highlands, which are characterized by their occurrence in the source areas of streams. Despite the indisputable importance of the montane peatbogs in terms of runoff conditions, their influence has not yet been conclusively clarified. Montane peatbogs are a particularly important topic for the Šumava region, where they represent a fundamental element of the landscape. The study site is therefore situated in one of the Šumava's spring areas - the Rokytka watershed. As part of this thesis, the issue of the hydrological function of the monitored peatbog has been viewed mainly through the differences in the fluctuation of the groundwater level in different parts of the peatbog. At the same time, the influence of the precipitation on the change in the groundwater level in the peatbogs and on the runoff response of the Rokytka brook has been monitored. Precipitation is the only source of water for the highlands and its influence is therefore crucial. Although several previous studies have focused on the influence of this highland on the runoff conditions of the Rokytka brook, groundwater levels from manually measured probes have not yet been analysed....
Mapping of water quality in Prague creeks with GIS
Thompsonová, Tereza ; Matějíček, Luboš (advisor) ; Benešová, Libuše (referee)
This thesis is focused in using of Geographic Information Systems (GIS) for mapping water quality in Prague creeks. The theoretical section focuses in a description of GIS and selected GIS projects (SWAT, ZABAGED) including a description of using GIS abroad. Working processes of chemical analyzes required to determine water quality and pollution sources in the area of urbanized basin are explained in the task. The practical section is focused in processing of data, especially mapping of selected creeks and sampling profiles using GIS. Obtained data is processed in tables and charts and used in correlation analysis. A purpose of the project was to demonstrate a possibility of GIS for modelling basin and its parameters.
Ecological condition of streams in urban areas. Case study of the Rokyka basin.
Stádníková, Monika ; Matoušková, Milada (advisor) ; Králová, Magdalena (referee)
The thesis deals with the status assessment of the stream in urban areas. The study area is the stream Rokytka in Prague. The method Hydroecological monitoring HEM (Langhammer, 2007, 2013) was used for the thesis based on field hydromorphological survey. This method is compatible with the Water Framework Directive 2000/60/EC. The thesis also includes assessement of the rainoff regime and water quality based on the available hydrological and hydrochemical data. As a final result, it was found out the stream Rokytka achieves III. hydromophological state - average state. The water quality state does not meet the requirements of the environmental standards quality. In the urban landscape, it is necessary to find a suitable compromise between flood protection and good environmental conditions. Powered by TCPDF (www.tcpdf.org)
