Study of vineyards irrigation system near near the Chorvátsky Grob village
Jarová, Nicole ; Kameníčková, Ivana (referee) ; Hyánková, Eva (advisor)
The bachelor´s thesis concerns the design of a drip irrigation in the selected location of the vineyard in the village of Chorvátsky Grob. The study focuses on the importance and partition of the irrigation in the chosen location. In the first part of the bachelor thesis, there is a description of the irrigation systems history, the irrigation division, the division of irrigation systems and types of droppers. Subsequently, the description of the micro-irrigation is included. In that I describe the characteristics of a drip irrigation and I evaluate the advantages and disadvantages of the drip irrigation. I describe the types of droppers with the technical conditions and components needed to build the drip irrigation. All factors affecting the irrigation uniformity and factors affecting irrigation water quality are described. Then I present the method of water treatment used in the drip irrigation and the method of the water transport to the irrigated land. In the next chapter, I describe the division of vine types, the composition and the material composition of grapes. At the end I propose the drip irrigation technology in a particular area (the agricultural cooperative farm, vineyard Chorvátsky Grob). All the land-specific data have been processed and the calculation of the water demand for the drip irrigation for this location has been proposed, especially for critical months. Based on data and calculations, I propose to ensure the irrigation for individual sectors. The necessary water intake and minimum operating pressure in the individual sections have been considered. Map data have been processed in the AutoCad programme.
Vliv chemických zdrojů znečištění na jakost povrchových vod v povodí Horní Vltavy
NEKOLNÝ, Tomáš
The diploma thesis is focused on the issue of surface water pollution, which is one of the biggest problems of the contemporary world. The pollution of watercourses and reservoirs worsens the quality of aquatic ecosystems as well as ecosystems in their surroundings. The typical sources of surface water pollution include especially point sources (human settlements, industrial sites) and land resources (agriculture). While the point sources of pollution can be monitored, the situation is far more complicated for the field sources. In agricultural farming, the fertilizer residues, pesticides and other substances come into the groundwater and the surface water. The aim of this work is to find out the quality of surface water in the measuring profiles (river Malše), to find out the hydrological situation during the year and to evaluate the impact of chemical pollution sources influencing the quality of the surface water in the river basin.

Halačka, Karel ; Adámek, Zdeněk ; Jurajda, Pavel ; Mareš, J. ; Kopp, R. ; Grmela, J.
The aim of the methodology is to provide managers and users of small water reservoirs Landštejn type with methodological tools for optimization of the water quality monitoring based on the current level of knowledge and research. Furthermore, provides a design of a methodology for fish community monitoring and optimization of treatments to reduce unwanted fish species and strengthen the status of suitable fish species with the aim of achieving the topdown effect and maintaining or improving water quality in these water reservoirs. The presented methodology summarizes the findings obtained during the monitoring and evaluation of selected parameters of water quality, planktonic and fish communities in water supply reservoirs Landštejn in recent years. It also contains an evaluation of applied treatments, focused mainly on fish stock. Unwanted fish species were caught and the predatory fish were stocked with the aim of optimizing the fish community composition and positively influencing the quality of the water in the reservoirs. The methodology contains recommendations for monitoring of the water quality in the reservoir, including monitoring of planktonic communities, monitoring of fish and recommended manipulation with fish stock. The methodology provides guidance and information for optimization of monitoring and treatments for small water supply reservoirs of the Landštejn type.

VN Sedlice – Experimental bottom sediment removal
Vrzák, J. ; Borecký, K. ; Borovec, Jakub
The report describes the progress of the mining experiment leading to the removal and deposit of bottom sediments from the reservoir. The report includes monitoring of technological conditions and the influence of mining and processing of sediments on the water quality in the reservoir.
Technical and technological audit of the water treatment plant
Jedličková, Tereza ; Svoboda, Pavel (referee) ; Kučera, Tomáš (advisor)
The aim of the submitted diploma thesis is the implementation and evaluation of the technical and technological audit of water management systems of water treatment plants – concretely Plzeň Water Treatment Plants.

Assessment of macroinvertebrates diversity in contex of physical river habitat quality
Nováková, Barbora ; Matoušková, Milada (advisor) ; Havlíková, Petra (referee)
Research of macroinvertebrates is currently an important part of the assessment of stream quality. Basic characteristics influencing macroinvertebrates communities in the streams are elements from the external environment influencing streams, specifically basic geographic parameters of the site, land-use in the catchment and characteristics of the banks. These elements have a considerable influence on effect of the basic parameters in the stream, which are flow, sediment structure, input of organic material and pollution. Research part of the thesis is about the parameters influencing macroinvertebrates communities. Research area of this work includes three different catchments in the upper part of Blanice catchment area near Prachtice. There is one nature stream with forest in it's catchment, stream with a predominantly meadow basin and last stream is characterized by two distinct stretches - a revitalized section and a section with concrete bottom. The subject of this diploma thesis is evaluation of diversity of macroinvertebrates communities in all streams in the research area. Thesis evaluate communities of macroinvertebrate using a wide range of indexes (BMWP score, ASTP index, EPT index a diversity indexes) and compares their diversity by using rank-abundance graph. All results are summarized...

Quality of water and water touring on selected West Bohemia rivers
Šimice, David ; Šafránek, Jiří (advisor) ; Doležal, Tomáš (referee)
3 Abstract Title: Quality of water and water touring on selected West Bohemia rivers Aim: The main aim of the thesis was to find out if there are changes of water quality in the most significant West Bohemia rivers as a result of the changing approach to our environment in the past several years. Furthermore, to consider whether the water quality has changed in relation to finished water management projects and whether this change influenced using rivers for water touring. The observed rivers: Úhlava, Úslava, Radbuza, Mže, Berounka and Střela. Methods: The first part of the thesis, discussing the water quality, analyzes available data collected from written and electronic resources and discussions with experts. The gained material mostly within the last 10 years was organized, compared and summarized. The second part brings the evaluation by canoeists who regularly canoe down these rivers and can visually judge the water quality. This information was interpreted from semi- structured interviews with canoeists. Results: Our presumption that the water quality on the selected West Bohemia rivers is improving was proved, which is one of basic conditions for water touring as well. Keywords: West Bohemia rivers, water touring, water quality, pollution
