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.

This bachelor thesis deals with numerical modelling of groundwater flow and contaminant transport. This thesis consists of two parts. In the first part are briefly described and compared basic methods, which are used for solving problems of groundwater flow and substance transport. Further more are set up initial and boundary conditions, which are an essential part of the compilation model. The second part deals with models from location Bzenec, where was the leakage of chlorinated aliphatic hydrocarbons. Models were created in purpose to describe the extent of contamination and spreading of contaminants and also to predict the further development of the pollution.

This study summarizes some general findings of geological, hydrogeological, hydrological, structural and other conditions of the Cheb tertiary basin and descrides how these conditions are connected with circulation of graoundwaters and with appearance of mineral waters of different chemical composition and appearance of discharge of dry CO2. The final chapter shows information of changes of groundwater level at specific locations and periods of time by analyzing data gathered from borehole monitoring site of Czech Hydrometeorological Institute. Measuring of groundwater level was taken every day or every week, also average data of every month were taken. These data show variant changes of groundwater level which can be associated with definite events and this study shows if it is possible to associate some changes of groundwater level with exact events.

The subject of the thesis is to characterize the vertical stratification of quality and to determine the source of contamination of groundwater in the north part of the Třeboň basin. In the thesis the quality of groundwater in peat bogs, in the sediments of the basin as well as in the underlying crystalline complex is described. The quality of groundwater was monitored in boreholes which are distributed in the whole area of the basin. The quality of groundwater in the collecting line Horusice - Dolní Bukovsko is also described in the thesis as it is the main source of drinking water in the area. The quality of groundwater is compared with the regulation 252/2004 Sb., which specifies drinking water hygienic requirements. For demonstrating groundwater flow and contamination propagation in parts of the basin a hydraulic model of groundwater flow was made. A part of the thesis is an evaluation of significant sources of contamination in the north part of the Třeboň basin and of the tendency of development of contamination propagation. Measures to protect and to increase the quality of groundwater are subsequently proposed. The quality of groundwater in the north part of the Třeboň basin is varying. There is groundwater meeting the drinking water criterion in the regulation 252/2004 Sb. but there is also...
