Development of surface water quality in selected rural areas of the Elbe River basin
Mrkva, Luboš ; Janský, Bohumír (advisor) ; Pechar, Libor (referee) ; Kodeš, Vít (referee)
Development of surface water quality in selected rural areas of the Elbe River basin Water quality is an enduring issue in water management and has global importance. This work deals with surface water quality in the Elbe River basin, focusing on river basins in agricultural and rural areas where surface water quality remains a significant ecological problem. As part of this work, two watersheds with a significant representation of agriculturally used areas were chosen: the Mastník River catchment, which flows into the Vltava River, and the Šlapanka River catchment, which flows into the Sázava River. In the case of the Mastník stream, the work deals with the basin itself and changes in water quality in the Mastník bay, which is part of the Slapy reservoir located on the Vltava River. Water quality was analysed using the concentration of selected parameters through long-term field research supplemented with data from the State Enterprise of the Vltava River basin. In this part, it was proved that constructing new wastewater treatment plants (WWTPs) gradually improves the overall water quality. However, the parameter chlorophyll-α and the lack of dissolved oxygen remain problematic. The finding of high concentrations of chlorophyll in the stream is followed by an assessment of the changes in water quality in...

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.

Mapping Of Litavka Basin Using GIS
Barešová, Magdalena ; Matějíček, Luboš (advisor) ; Benešová, Libuše (referee)
The purpose of this work is the use of the Geographic Information System (GIS) for a model evaluation of a selected area of Litavka basin. The theoretical section focuses on the description of GIS, GPS and selected GIS projects (ZABAGED, National inventory of contaminated sites, ArcČR500). The practical area focuses on processing the data. There were several thematic layers created including: the digital terrain model (DTM), thematic layer on the slope, aspect to the north, and a layer of aerial photographs containing current and historical status. The project was completed with a thematic layer of test sampling profiles. The practical part included a chemical analysis of water samples from Litavka carried out in Laboratory of water protection of the Institute for Environmental Studies. The purpose was to demonstrate the influence of rural agglomeration on water quality changes. The quality grade of the flow was determined by appointed indicators according to the Czech Technical Standard CSN 75 7221 Water quality. All data was entered into the GIS project. Key words Geographical Information System, mapping, Digital Terrain Model, Global Positioning System, Litavka, river basin/watershed, quality of surface water
