Operational and Technical Condition of Separation Equipment in Water Treatment Plants
Pešout, Jakub ; Roh, Robert (referee) ; Kučera, Tomáš (advisor)
The goal of this thesis was to determine the operational and technical parameters of the separation objects in water treatment. The first part is a theoretical and provides basic information on this issue. The second part contains the evaluation criteria created by the obtained information for individual objects and gained in practice by personal visits of selected treatment plants of water. In the last part we can find application of these criteria in water treatment in practice. There is also included the final evaluation of the researched condition.

Office Building
Tručka, Jiří ; Mizerová,, Lenka Smolková (referee) ; Smolka, Radim (advisor)
This master's thesis deals with project documentation of an office building with commercial premises, cafe, and canteen. The building is located in Žďár nad Sázavou, on plot 2197. The access road is from the north side. The building has 6 floors above ground and 2 underground floors. The building is designed as monolithic reinforced concrete frame with shear core. Basement consists of monolithic reinforced concrete walls. Whole building is based on reinforced concrete slab, which is supported by a system of piles. The external wall is designed from clay blocks. The facade is ventilated.

Provision of alternative refuse collection for a real estate surrounded by foreign property
Kvapil, Radek ; Štindl, Michal (referee) ; Klika, Pavel (advisor)
The thesis deals with possible ways of drainage and wastewater disposal. The issue of wastewater discharge to the environment has been closely monitored in recent years, and there is an apparent effort to improve the current situation.The dissertation discusses and compares three selected options – access to improved sanitation, building reservoirs and domestic wastewater treatment plant.The final section is dedicated to a comparison of acquisition and operating costs over time and to subsequent evaluation of the most suitable option. For the sake of clarity and assessment of potential solutions, the locality in the administrative area Vysoké Mýto - Domoradice has been selected as a model. The local authorities have been designing a public storm sewer, and given that it is surrounded by land, this issue will need to be addressed.

Cast-in-place tank of sewage plant
Matušík, Petr ; Sliwka, Pavel (referee) ; Strnad, Jiří (advisor)
The topic of diploma thesis is to design a cast-in-place tank of sewage plant. The tank has circular shape without ceiling slab and will be completely covered in by soil on sides. The tank is a simple construction with complex relation of foundation. It means the construction will be founded according to second geotechnical category. The tank has to be designed as waterproof construction, which is reached by making white tank system. Calculation was made according to ultimate limit state and limit crack width was assessed according to European standards.

Remediation of groundwater contaminated by oil products
Kabelíková, Eva ; Úterský, Michal (referee) ; Biela, Renata (advisor)
This bachelor thesis describes rehabilitation of groundwater which is contaminated with oil products. The first part describes methods of collecting groundwater from the sources together with forms possibilities and properties of groundwater pollution and characteristics of pollutants. In addition, oil substances and their properties are described, followed by methods of groundwater protection and liquidation of accidents. At the end of the first part, ways of remediation of contaminated groundwater are presented. The second part of the thesis contains an overview of companies that carry out remediation work and description of their solution technologies.

Treated Waste Water Irrigation
Kohut, Rafael ; Hyánková, Eva (referee) ; Kriška-Dunajský, Michal (advisor)
The thesis deals with the issue of simulation of treated wastewater irrigation by the HYDRUS 2D software. The first part of the thesis is designed as a theoretical research of academic information and knowledge. It aims at introducing the issue of treated wastewater utilization for the purpose of the irrigation. Furthermore it provides basic theoretical information on numeric simulation of the dissolved materials motion and transport in the soil. The last chapter of the theoretical part describes the calibration of the simulation by the HYDRUS 2D software. The second part of the thesis is devoted to the formation of filtration columns placed in the chosen site of the root zone wastewater plant. Within the filtration columns the automatic irrigation was formed and set off. Measuring of humidity in filtration columns was taking place for 81 days as well as the water sampling after the flow through the soil horizons. On the grounds of the measuring results the calibration of numeric simulation was carried out by the HYDRUS 2D software. The last part of the thesis presents the applications through the extending and alternation of the modelled setting. The main aim of the thesis is to calibrate the model and propose a general solution to advancement at realization of irrigation details when using the treated wastewater for the purpose of irrigation.

Návrh managementu jímacího území vodního zdroje Nová Ves u Pohořelic
Ohryzek, Dominik
The quality of the water in source Nová Ves near Pohořelice was degraded by an above-limit nitrate concentration, which caused complications with use of the water for drinking purposes. The causes of this pollution have not been fully confirmed, one of the possible factors is increased mineralisation of humus substances in the soil (Leugner et al. 2021) after deforestation of spruce and pine stands. These died gradually during the drought and bark beetle calamity in 2015 and the following years. The presented thesis propose management principles of site with respect to the water management needs of the resource owner. There were proposed phytoremediation techniques using tree species grown in a coppice manner. Management is also focused on the care of remaining vegetation in the area, where close to nature species composition prevails.

Reaction of surface water and groundwater to the hydrological drought in 2015-2018 in the Upper Lužnice river
Husarik, Pavel ; Burian, Alois (advisor) ; Šobr, Miroslav (referee)
The Bachelor's thesis focuses on the examination of drought as an extreme and complex phenomenon. It provides a clear overview of its types, causes, and impacts on the landscape and society. Furthermore, it discusses the response of surface and groundwater to dry periods. The theoretical conclusion specifically analyzes the period of hydrological drought in the Czech Republic between 2015 and 2018. In the practical part, the characteristics of monthly and annual discharges are evaluated, and the response of surface and groundwater is assessed using data. Data from both surface and groundwater, as well as precipitation totals from the ČHMÚ (Czech Hydrometeorological Institute) observation network, were utilized. Average precipitation totals were also taken into account. The evaluation of time series was performed in terms of precipitation-runoff regime, including exceedance lines and monthly flow distributions. The results indicated that the lowest average flows were recorded in 2018, which also saw the lowest average groundwater level. Conversely, the highest number of dry days occurred in the studied period in 2015. Keywords: surface water, groundwater, hydrological drought, the upper Lužnice river
