Vliv drenážního odvodnění na jakost vody
Svobodová, Natálie
The thesis deals with the issue of drainage of agricultural soils and its effect on water quality. The aim was to describe the basic concepts associated with drainage systems, especially with controlled drainage, and specifications of the quantities measured in the field. Data obtained from monitoring of drainage water quality at the controlled drainage site in Uherčice has been evaluated. Based on this data the effect of regulated drainage and drainage without regulation on the quality of drainage water was compared. The results indicate that conductivity is most influenced by the nitrogen content in the water. Although the concentrations of substances are largely higher in regulated drainage, their proper controlled drainage can encourage the retention of substances in the area, while reducing the removal of substances by the drainage system from the area.

Hypodermic and drainage runoff
Hubinger, Lukáš ; Datel, Josef (advisor) ; Vaněk, Jiří (referee)
The BSc thesis deals with hypodermic and drainage runoff, possibilities of its determination, with its place in the hydrologic cycle and impacts of anthropogenic activities. There are types of runoff, possibilities of its description one by one in the thesis. The thesis also includes information about agricultural drainage, its influence to the landscape as whole, types of drainage, about advantages and disadvantages of drainage systems and about actual situation of drainage systems in the Czech Republic. There are description in detail pluses and negatives drainage runoff in the thesis, there are description possibilities of its modernization, about actual situation of drainage systems and it is influence to the landscape.

Analysis of the impact of drainage systems for surface water quality
KAMARÝT, Jiří
This Diploma thesis is following the previous Bachelor thesis which mainly focuses on drain systems and the analysis their influence of the quality of surface water. The literature review contains the description of surface water quality, substances causing the eutrophication, drainages and drain systems. Also the mechanisms influencing the change of quality of surface water after the the drain systems construction are included. In the chapter "Methodology", there are the statistical methods for concentration evaluation exposed, also the detiled description of setting up the crossing of empirical line for concentration substances in water and the drain separation methods with the aim to set the average phosporus and nitrogen concentration within the each drain component are covered. All of the evaluation which are followed by methodology in relation to sites of interest are described in detailed way in the chapter called "Material". The chapter "Results and discussion" focuses on overall description and evaluation of all the results.

Analysis of factors affecting a direct runoff from the catchment area
NEUBAUEROVÁ, Andrea
This diploma thesis follows my bachelor thesis. The main purpose of the bachelor thesis was to clarify fundamental terms and to explain the sorting of particular parts of a direct flow that involves both the surface saturated flow and the hypodermic flow. This diploma thesis is focusing on the origin of direct flow in a river basin. Specifically, it deals with river sub-basin P6, P52, and P53, which are located in Kopaninský potok river basin. Furthermore, it deals with Jenín I. and II. river basins and the last analysed is Ostřice river basin (SO2). Factors influencing direct flow are researched on all river basins. It is impossible to say that the origin of direct flow is caused solely by a single factor; it is always the result of multiple factors. Among these factors belongs the atmospheric precipitation, type of soil, vegetation, climatic and anthrophogenic conditions, land use, and inclination of the area. The bachelor thesis explains the issues of multiple methods of flow separation, but this diploma thesis is primarily focused on two methods for calculation of ratio between the direct and the total flow. 1) Empirical method GROUND, which is used to separate hydrographs of medium daily river basin flow. 2) Method of digital filter by Lyne Hollick separate fast and slowcomponents from the overall concentrated flow and are based on the theory od signal analysis. Afterwards, the results of flow separation were compared to the factors influencing the origin of the direct flow. The daily total flow rates for every analysed river basin were used as the input data for calculating the flow separation.

Direct run-off - formation and separation methods
NEUBAUEROVÁ, Andrea
The bachelor´s thesis occupies with an issue of a direct flow. The main purpose is the explanation of the basic terms of the issue and the explanation of the sorting of particular parts of a direct flow, that involves a surface saturated flow and a hypodermic flow. Subsequently the thesis describes its participation in the hydrogeological cycle, which means the participation in the permanent circulation of a surface and underground water on Earth. The extreme precipitations are dangerous due to their force, total sum and intensity. The inception of hydrological occurrences like floods or dry seasons is possible owing to this. The fallen precipitations have a big influence on a surface flow and a transportation of soil particles. The thesis is focused on the inception and the genesis of a direct flow. Further it focuses on the factors that influence the flow. Among these factors belong climatic and anthrophogenic conditions, vegetation, type of soil and atmospheric precipitations. There are clarified selected methods of potential separation which are explained and described in detail. This part of the issue mentions CN curve method, GROUNG method, MPGM, analysis of dropped subdivisions and finally method of digital filter (Chapman). These methods divides the flow on an elemental flow and direct flow.

A effect of drainage system on quality of surface water
KAMARÝT, Jiří
My bachelor thesis is focused on quality of surface water. My thesis is written by the form of framework literature search. And it inteferes with the fields of climatology, geology, topography and especially hydrology and water chemistry. The content of the literature search is getting acquainted with the reasons of building of underdrainage and its particular development in the Czech Republic. Furthermore there are contrivances described which cause the change of quality of water after building drainage system and quantification of holding of drainage systems in concentration of analytes of surface water. Water is important environmental component in nature and it is necessary to pay attention to its high quality. The soil contrivances, causing pollution of surface water, were considerably affected by building of drainage system in a large area of the Czech Republic in 1950?s. Those drainage systems were built due to intensive agriculture. But there were no thoughts about following conservation of countryside, particularly water and soil. There still have been consequences of insensitive interference with countryside even these days. My bachelor thesis can be used as a base for my thesis which is supposed to enrich it with my own measurement and further comparison.
