Dewatering of foundation pit - numerical analysis
Krejzar, Vojtěch ; Boštík, Jiří (referee) ; Miča, Lumír (advisor)
The subject of the presented thesis is a foundation pit dewatering numerical analysis. The study is introduced with practical examples and the summary of the necessary theory. Individual subtasks are modeled as two or three-dimensional problem on a chosen foundation pit example. A comparison with analytical methods and theoretical knowledge about the problem is made. The studies focus on specifying the pumped water quantity, the shape of the depression curve, determining the size of the numerical model and the influence of the finite element network density. The steady-state flow cases, water table aquifer, a well system, sheet pile wall cutoff effect, surface drained pit and partial penetration cases are analyzed. The work proposes a method of modeling a well by FEM. The main output is a 3D analysis of a submerged excavation dewatered with a partially penetrated well system.

Influence of Building Environmental Certification on Price Valuation with Respect to the Building Life-Cycle
Mrňová, Zuzana ; Tichá, Alena (referee) ; Komosná, Milada (advisor)
The aim of this diploma thesis is an analysis and evaluation of environmental certifications influence on rental rates and operating costs of administrative buildings. The analysis is conducted for administrative buildings because these are the most frequently certified buildings in the Czech Republic. To fulfil this defined goal, two office space offer price databases in Prague and Brno are compiled. The first database is consists of office space offer rentals which possess environmental certification. The second database is also compiled of building offer rentals but without environmental certification. Based on these two databases the effect of environmental certification on rental rates using paired t-test is examined. Simultaneously, effective operating costs of buildings located in Brno are analysed, and it is evaluated whether and if so, at what intensity their amount is affected by environmental certifications.

Interpretation and use of monitoring data from water supply wells
Kutnarová, Karolína ; Pastuszek, František (advisor) ; Hrkal, Zbyněk (referee)
The life of the hydrogeological well is not important only in petroleum geology but also in the water industry. Nowadays, when the demand of water rises, it is necessary to ensure the smooth running of the wells and care as much as possible about their condition. The aim of this thesis is try to apply the methods of production analysis commonly used in oil production in the oil industry for water supply wells. In the thesis I will focus on monitoring the productivity of the well with regard to increasing the hydraulic losses caused by clogging. iv

Use of conductivity meter LTC to characterize the flow of groundwater in well: Use of artificial well and field monitoring
Rodovská, Žaneta ; Bruthans, Jiří (advisor) ; Procházka, Martin (referee)
My Master thesis is focused on a tracer dilution technique in the well using automatic conductivity logging probes LTC Levelogger (Solinst co. Canada). The main aim of my thesis was to test the application conductivity meters LTC to track the movement of fluids in wells. Different set up were used moving probes with unmodified sensor slit, moving probes with modified sensor slit, probes measuring at fixed points, combined moving and fixed points probes and results were compared. 15 wells in quaternary and 11 wells in Bohemian Cretaceous Basin were measured, some of them repeatedly. The comparison of results indicate that the highest apparent flow velocity have probes with unmodified sensor slit. On the other hand fixed point probes indicate flow velocity, which is 40 - 50% lower at the same wells. The combination of the stable positioned probe LTC and the moving probe LTC has about 40% higher flow velocity than the rate of steady probe LTC placed in the well. The results also indicate that extremely slow velocity values (below approximately 0.02 m/day) can be measured only with LTC probes at fixed points. Modified probe slit was tested in the laboratory in plexi-glass tube using fluorescein and NaCl tracers. Unfortunately the modified geometry of measuring slit does not show distinctively better...

Prague fountains in the Renaissance
Linartová, Klára ; Jarošová, Markéta (advisor) ; Zlatohlávek, Martin (referee)
Abstact The bachelor thesis deals with the Prague Renaissance fountains and wells. In the introduction the main attention is focused on the importance and nature of the water system in Prague, mainly in the Prague Castle, Lesser Town and the Old Town, where the most important monuments are preserved and which are the subject of this work. The main content of the work is formal and iconographic assessment of individual fountains, wells and other water reservoirs. The focus is on the circumstances, to the changes observed landmarks succumbed over time, and any subsequent modifications, co-location and in particular the form of artistic design and iconographic analysis. The conclusion is devoted to typological comparison with other major monuments in the Czech Land and broader European context. The work is structured as a catalog of important Renaissance fountains in Prague during the Renaissance with regard to their typology.

Use of conductivity meter to characterize the flow of groundwater in well: Use of artificial well
Rodovská, Žaneta ; Bruthans, Jiří (advisor) ; Kobr, Miroslav (referee)
This Bachelor thesis is focused on the geophysical "tracer dilution technique" in the well. The main aim of my thesis was to test modern autonomous conductivity meter (Levelogger, Solinst co. Canada) for this method in the artificially assembler well, where the real flow rate can be measured and controlled unlike in case of real wells. To compare the flow rate directly measured on inflow tubes to well and indirectly derived from tracer dilution technique the mean residence time in vertical segments was used. Based on 8 experiments the autonomous conductivity meter and also conductivity meters with probe on cable can be used for tracer dilution technique. Experiments clearly demonstrated that salt solution is slowly leached even from dead zones in unscreened part of the well at lest several tens of cms from boundary with creened casing. Salt solution is migrating from dead zones to sreened parts of the well. As a result the tracer dilution technique gives up to 2 times slower horizontál flow rate than directly measured flow. Similar effect may exit on real wells. Powered by TCPDF (www.tcpdf.org)

Property valuation type of summer camp
Šťastný, Miroslav ; Levstek (Bradáčová), Šárka (referee) ; Šmahel, Milan (advisor)
Diploma thesis “Property valuation type of summer camp” is focused on recording and valuation of all the immovable property, which are parts and outbuildings of summer camp near the Vranov dam. Theoretical part of this thesis deals with basic terminology and utilized valuation methods. Short locality characterization and relevant real estate market are described in the practical part. Main focus of the practical part is actual valuation of immovable property using methods described in theoretical part. After that, calculated and estimated prices are evaluated and analyzed.

Plumbing Systems for Accommodation Facilities
Možná, Pavlína ; Vrána, Jakub (referee) ; Bárta, Ladislav (advisor)
Master’s thesis "Plumbing systems for accommodation facilities" is processed in the form of project documentation plumbing according to applicable regulations. Designed building has five floors, basement. The ground floor restaurant and relaxing part of the hotel, in the remaining floors are guest rooms with 75 beds. One room is completely wheelchair. The building is located outside urban areas without connection to public utilities. The work focuses on the design of plumbing hotel and presents two variants of the possible solutions for waste water from the building. Building water supply is secured from drilled wells and the proposed pumping equipment.

Designing of the Objects for the Groundwater Captation
Pavel, Marek ; Krejsová, Věra (referee) ; Kučera, Tomáš (advisor)
This bachelor thesis deals with stuff connected with designing groundwater extracting. First part is focusing on history and possible ways how to do it including other problems which goes with this topic. This part talks about laws and codes that is need to know. Second part continues with more practical side. It means drilling, what technology to choose and some example how to design a well.
