NOx production and elimination content in the flue gas
Čech, Jaroslav ; Šnajdárek, Ladislav (referee) ; Hrnčířová, Michaela (advisor)
The Bachelor thesis deals with oxides of nitrogen, resulting from the combustion process. The thesis is concentrated mainly on the description of the emergence mechanisms and on the various measures that are used to reduce their concentration. Part of the thesis is also focusing on legislation in the field of air protection, with the values of the emission limits valid for the Czech Republic and the European Union.

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...

Land adjustment evaluation in light of water protection in Southern Bohemia.
FRITSCHOVÁ, Hana
The aim of the thesis is to evaluate effects of natural and human activity on water quality of Budsky stream basin, futher assessing current water protection and proposing improvements in the form of differential protection zones. The basin is located on Besednice, Soběnov and Malče cadastral areas and extands to second grade of a water supply protection zone of Rimov reservoir. During terrain reconnaissance of the area were all the factors that could contribute to impaired quality of water in the basin taken into the account; from point source pollution to signs of erosion on the slopes of the basin. Futhermore the link between agricultural pollution, agricultural land erosion, land consolidation and protection of water was explained. Also pedological, hydrological and climate researches were conducted. The result is a redefined design of the water protection zones in question.
