Importance of environmental elements (water environment and greenery) in urbanized areas of the Czech Republic
 HAVRÁNKOVÁ, Lucie
The aim of the dissertation is to provide an analytical comparison of the effectiveness of using of the environmental potential of watercourses and greenery in urbanized areas/cities of the Czech Republic (ČR). The work is divided into a part of physical-geographical and sociological assessment and research. The physical-geographical analysis will provide the results of watercourse use in the city using the Urban River Sustainability Index (URSI) and watercourse availability analysis. In the area of eva-luation of cities in terms of greenery, the results are obtained through the calculation of the Indicator of the General Quality of Greenery in Cities (IOKZM) based on the Coefficient of Ecological Stability (KES) and the evaluation of the share of greenery in cities. Sociological research provides the user's opinion on the positive environmental contribution of the watercourse in specific urbanized areas, based on the results of quantitative and qualitative research. This section is statistically evaluated using logistic regression (LR) and multivariate correspondence analysis (CA). The overall results of the work create an overal image of the importance of environmental elements (water environment and greenery) in urbanized areas of the Czech Republic. They draw attention to the current state of Czech cities and suggest possible improving solutions not only for their changing climatic situation.

Hydrogeological character of selected hardrock environments and groundwater recharge in populated areas
 Krupař, Josef ; Bruthans, Jiří (advisor) ; Slavík, Martin (referee)
The purpose of this thesis is to adress the hydrogeology of hard-rock environment and groundwater recharge in urban areas. The theoretical part describes hydrogeology character of granite and ophiolite rock environment with emphasis on features such as transmissivity, storativity and hydraulic conductivity that corresponds to the fissuring of the rock environment. It is clear that fault tectonics is the most important factor that influence the hydraulic conductivity. Storativity, on the other hand, is most affected by fissured systems. Ophiolites are a more significant water supply aquifer than granites in terms of storativity. This thesis also describes groundwater recharge in urban areas and not only from precipitation but also through surface water reservoirs, leaks from pipeline network and by import of water from surrounding watershed. Practical part compares values of precipitation from 2013 to 2022 from four ČHMU stations. It compares PET (Potential evapotranspiration), API (antecendant precipitation index) values and their difference. Subsequently, in the practical part, the normalized relative groundwater recharge from the measured values of the well level is compared with the flow rate at all monitored locations and it is evaluated whether the time course of the recharge according to the...
