Rainwater-treatment and rainwater utilization
Štefek, Miroslav ; Kárník, Jan (referee) ; Štigler, Jaroslav (advisor)
The aim of this bachelor thesis is developing searches which are focused to treatment with rainwater and it's next utilization. We can find general information about situation in Czech Republic in this work and we can also read about products for rainwater treatment which are available in the market. There is a calculation for house too where we can see if it is advantageous step if we'll purchase rainwater treatment products.

Infiltration - the elementary hydrological process
Salač, Jan ; Doležal, Petr (referee) ; Kameníčková, Ivana (advisor)
The bachelor thesis deals with the evaluation of water infiltration into the soil in the area of interest of the village Šakvice. Measurements were carried out on 13 May 2009 and 10 September 2009 on arable land with convential tillage (with ploughing). For measurements were used double ring infiltrometers. To evaluate the cumulative infiltration and infiltration rate were used equations of Kostjakov, Mezencev, Philip and three-parameter equation of Philip‘s type. The results were processed numerically, plotted and then compared.

Measurement of infiltration in the field using MiniDisk infiltrometer
Vláčilíková, Michaela ; Doležal, Ing Petr (referee) ; Kameníčková, Ivana (advisor)
The diploma thesis deals with measuring of infiltration by MiniDisk method and its evaluation, but also with analysis of intact and grab soil sample, by means of which it is possible to assess the soil quality. The measurements took place on 30.4.2019, 4.5.2019, 12.5.2019, 2.6.2019, 30.6.2019, 2.7.2019, 31.8.2019 and 21.9.2019 on grassland near the town of Luhačovice. Grab and intact soil samples were taken from the upper soil layer and processed in a pedological laboratory. The Zhang method was used to evaluate the infiltration results. The results of soil analyzes and infiltration were processed numerically, plotted and subsequently described and compared.

Determination of hydraulic characteristics of soil in a selected area
Salač, Jan ; Doležal, Petr (referee) ; Kameníčková, Ivana (advisor)
The diploma thesis is focused on issues of measurement and evaluation of hydraulic characteristics of soil. In the literary research, the definitions of hydraulic conductivity and retention curve of soil moisture, their measurements in laboratory and field conditions and the prediction of these characteristics by using of pedotransfer functions. In the practical part of the diploma thesis, an evaluation of the hydraulic conductivity of soil from the experimental areas near the village Bohaté Málkovice. Two-cylindrical and mini-disc infiltration meters were used for field measurements, and a constant-gradient permeameter was used in the laboratory. Physical and empirical equations were used to evaluate the hydraulic conductivity. The results were processed numerically, tabulated and then compared.

Use of buildings rainwater for irrigation and soaking ind the Moravské Křižánky village
Hubený, Michal ; Kameníčková, Ivana (referee) ; Hyánková, Eva (advisor)
The bachelor thesis deals with the issue and utilisation of rainwater. The thesis is divided into two parts - theoretical and practical. Theoretical part consists of general rainwater distribution, the formation of individual rainfall - its composition, quality, surface run-off, individual possibilities of water purification, accumulation and infiltration. The ways of using rainwater in households and gardens are also described in thesis. The practical part deals with the use of rainwater around a family house in the specific location. The area is located in the village called Moravske Krizanky in Vysočina region. In conclusion, a complete solution for rainwater accumulation, irrigation and infiltration was developed.

Analysis of properties of openings with respect to infiltration in buildings
Zapletal, Miroslav ; Klepárník,, Jan (referee) ; Polášek,, Josef (referee) ; Šťastník, Stanislav (advisor)
The dissertation thesis is primarily focused on the analysis of the properties of openings constructions with respect to infiltration in constructions, specifically related to the permeability of opening fillings and the permeability of buildings. The main aim of this work is to find out how the overall air permeability of a building can be influenced in relation to the openings and their properties, which are related specifically to the air permeability at the specified tightening degree of the used all-round fitting. In relation to the overall air permeability of the building, the energy balance of a particular building will be calculated in cooperation with the determined results of the air permeability of the building at a defined degree of tightening of used all-round fitting at levels 0%, 50% and 100%. The results of tests and measurements will be reflected in a concrete calculation of the energy balance of the assessed building in the form of numerical simulation.

The design of the small water reservoir
Galuška, Martin ; Hyánková, Eva (referee) ; Doležal, Petr (advisor)
The concept of this work is to assess options of a small water reservoir design on the selected area Bezměrov. Part of the work refers to different types and functions of small dams and their water management solutions. There is a geological survey presented which is describing the composition of the soil layers and investigating available materials for dam constructions. Water balance has been processed for considered dam profiles evaluating specific outflow of the catchment area, vapor and leakage through a simplified design of the dam. That creates a basic conception about possibilities of water manipulation in this area. Based on this evaluation there are several options processed to explore the retention effects of this two small water reservoirs system above Bezmerov locality.

Ways of rain water disposal or reuse in the newly built production compound near the Hodejice village
Kabátek, Stanislav ; Menšík, Pavel (referee) ; Hyánková, Eva (advisor)
The task of this work is to solve rainwater management, which will be captured on the roof and on the paved areas due to the planned construction of the production factory in Hodějice village. Outflow of rainwater could glut culvert beneath railway line. Resolving rainwater management is a prerequisite for obtaining a building permit. The solution is a system of infiltration blocks with controlled drainage, which ensures the retention and not-increasing of the original rain outflow from the land. For solution manual calculation according to ČSN 75 9010 and the application from the ASIO manufacturer is used. The benefit of this work is the design of a system for automatic irrigation of vegetation on land and a system for eventual maintenance and washing of technical equipment. This will use the rainwater that would otherwise outflow meaningfully.
