The project of the soil protection devices in the small watershed
Kravčenko, Matěj ; Kameníčková, Ivana (referee) ; Doležal, Petr (advisor)
The objective of this thesis is the project of the soil protection device in the small watershed. A municipality of Letonice in south-moravian county was analyzed for this purpose. This thesis contains the theory of soil erosion, theory of project of the soil protection and theoretical concepts for calculating the erosion washes using the Wischmeier-Smith (USLE) model. The area analysis was performed in GIS environment and it was based on a digital model of the terrain.

Creation of Documentation for construction with design of control and visualisation for luxury house
Doležal, Petr ; Klaban, Jaromír (referee) ; Bátora, Branislav (advisor)
The thesis deals with an intelligent wiring including a control and visualization design for a family house. The goal of the thesis is to create a project of a high and a low voltage wiring for a family house including a design of an intelligent wiring. The thesis introduction describes an intelligent wiring and a comparison with a classic wiring. The next two chapters deal with the most used systems and a detailed description of the selected system Foxtrot. The chapter number 5 addresses the project documentation creation for a high and a low voltage wiring. A performance calculation of a heat pump used for heating is described in the following chapter. The functional program for control and visualization of heating, lighting, shading and security is described at the end of the thesis.

Design of the multipurpose small water reservoir
Galuška, Martin ; Hyánková, Eva (referee) ; Doležal, Petr (advisor)
Thesis develops a simplified design of water management and construction solution in the area of Bezmerov. In the theoretical part basic functional objects are briefly described. Work itself is based on evaluation of landscape morphology from delivered countour lines and geological analysis and following design solution for dry retention water reservoir. For drawing part will be used programs PowerCivil – in which will be created direction solution for body of the dam, flooded area and their cross-sections and horizontal cuts. These will be further processed in program AutoCAD. Retention effects will be reviewed with program HEC-HMS. Design of objects for the water reservoir will be followed with hydrotechnical calculations, drawings and descriptions.

Design of the multipurpose small water reservoir
Rumanová, Jana ; Hyánková, Eva (referee) ; Doležal, Petr (advisor)
Master's thesis aims to design a small water reservoir. It is the dry water reservoir which is situated above a built-up area. The main function of this reservoir is a flood protection. Digital terrain model is created in a program BENTLEY MicroStation V8i – Power Civil. Focusing points in a data file are used in a process of creating of the DTM. Adjustments are done in AutoCAD. Particular hydro-technical calculations are calculated in a program Microsoft Excel. A program HEC-HMS is used for an assessment of a flood wave transformation and a program HEC-RAS is used for a water runoff simulation via emergency spillway.

Determination of the functional volumes of the reservoir considering input data uncertainties
Paseka, Stanislav ; Doležal, Petr (referee) ; Szolgay,, Ján (referee) ; Marton, Daniel (advisor)
Damaging changes and interventions in the water cycle in our landscape caused mainly in the last century together with uncertainties from climate change are the cause of more frequent occurrences of hydrological extremes. In Hydrology, the most urgent problem is that the values of the long-term mean flows are decreasing in rivers as well as the yield of groundwater sources, but on the other hand, we cannot forget to the problem of extreme floods. In these consequences developing methods and tools to uncertainty analysis of the reservoir yield and of the reservoir flood protection is very important, useful and desired. The main aim was to determine the functional volumes of the reservoir considering input data measurement uncertainties and to quantify them and was explained how uncertainty took into account in results. The active storage capacity was determined from the historical series of monthly flows that were affected by uncertainties, next were applied on water evaporation, seepage losses of the dam and morphological volume-area curves. The simulation-optimization reservoir model was developed and temporal reliability as reservoir yield performance measures was applied. This model will extend the existing UNCE_RESERVOIR software. The flood capacity was determined from random flood wave variations were obtained by repeatedly generating uncertainty on the flood hydrograph. Software was developed based on the modified Klemes method, which was able to transform flood waves. The measurement uncertainties of data inputs were created using Monte Carlo method in both softwares. By connecting two softwares, the functional volumes of the reservoir under conditions of measurement uncertainties were complexly determined. The case study was applied to the real water reservoir, in the Morava River Basin. The result will be whether the dam is resistant to the current conditions, or the optimal design of the functional volumes of reservoir under conditions uncertainties.

Detached house with design office
Doležal, Petr ; Šoulová, Eva (referee) ; Utíkalová, Ivana (advisor)
The object of this bachelor thesis is to elaborate a project documentation of a detached house with a design office. This is a two-storey brick building with a partial basement, which is in a flat terrain. The roofing over the second floor is designed from the single-shell roof. The building is designed in the system Porotherm. The process layout allows a comfortable living for a family with 4-6 members. The design office is for 6 workers

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.
