The protection of small village Světnov against rural zone water
Humlíček, Aleš ; Novotný, Jaroslav (referee) ; Milerski, Rudolf (advisor)
The aim of this thesis is to propose appropriate flood protection measures in the small village Světnov, calculate the critical flood of guideline for very small basin and insert the data into the program HEC-RAS 4.1.0, where they will be further treated in order to find the most appropriate and effective solutions. As flood control measures will be designed two dry polders east of the village. Dikes should be designed so to be able to accommodate 100-year flood, which will be calculated according of guideline for very small basin. Of the materials community, we know that we need to convert flood into the existing pipeline, which is able to accommodate 1 m3/s. The thesis will design solutions dams, sewage channels and function objects in the program AutoCAD 2008.

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.

Safety Assesment of the Hostim Dam during Floods
Šilhánková, Lenka ; Hopjan, Pavel (referee) ; Jandora, Jan (advisor)
The aim of this Bachelor Thesis is to evaluate and subsequently evaluate the current state VD Hostim in the conversion of KPV with parameters PV100. Processing takes place according to the requirements of ČSN 75 2935. The content of the work is a description and summary of the basic data on the water structure the documents and the resulting values, including descriptions of hydraulic calculations. Based on the results, remedial measures will be proposed to secure the waterworks. These measures will help ensure the safety and reliability of the water structure.

Water management solution of Tršice reservoir
Chyba, Martin ; Fína, David (referee) ; Starý, Miloš (advisor)
The master thesis follows the bachelor's thesis entitled Water management solution of a small water Tršice reservoir. The object of the work is the completion of the water management solution at the Tršice reservoir. In the terms of the storage function of the reservoir, it will be a question of finding a possible increase of runoff for irrigation in the growing season of various crops. In the terms of the protective function, it will be a transformation of flood waves of Tršice reservoirs and below ponds.

Assessment of dam safety during the floods
Hala, Mario ; Jandora, Jan (referee) ; Říha, Jaromír (advisor)
The Diploma thesis deals with the safety assesment of the small water reservoir Bartošovice III during the floods, according to requirments of TNV 75 2935 (technical standard). First two chapters are devoted to the description of the dam purpose. Following chapter deals with the summary of basic information and documentation, including hydraulic analysis. In the following section maximum permissible safe water level is determined together with the maximum check flood water level in reservoir which reflects the flood wave transformation. In the final evaluation the comparison of the maximum permissible safe water level with maximum check flood level is carried out. At the end of the thesis recommendations leading to ensuring of reliability and safety of water reservoir are listed.

Measures to increase the transformation capacity of the Svitava inundation area in the Holásky - Chrlice section
Havran, David ; Roth, Tomáš (referee) ; Zachoval, Zbyněk (advisor)
This diploma thesis deals with the possibilities of using the left inundation area of Svitava river for purposes of transformation of the 100-years flood wave in Svitava. The area of interest is located on the territory of the Holásky and Chrlice city districts. SMS software with a hydraulic two-dimensional simulation model SRH was used to simulate the flow in the current state and variant solutions of the proposed state. Based on the results of the flow in the current state, two variant solutions of the proposed state were designed and simulated. The result of this work is the quantification of the change in the transformation capabilities of the area of interest in both proposed variants and followed by a recommendation.

Design of water reservoir for flood protection
Vláčil, Lukáš ; Holomek, Michal (referee) ; Paseka, Stanislav (advisor)
The aim of this thesis is to map an anti-flooding protection in locality Dobrá Voda near Hořice and to create suitable plan of a water retention reservoir. Retention reservoir works as a system for holding and transformation of flood wave and thus for dealing with floods. First part of this thesis covers general description of issues of floods, current legislature, anti-flooding measures and a description of flood wave transformation. Methods for determination of retention seepage of the reservoir are described in this part as well. Computer programmes (HEC-RAS, Transformwave) were used for the purpose of above mentioned determination. In the second part of this thesis the given locality is described including all the possible risks and plans of convenient anti-flooding measures. The results of appropriate software determinations are compared in this part of the thesis as well. A final plan of a suitable retention reservoir is based on the results of comparison.

Design of a small multipurpose reservoir in the cadastral area Velké Albrechtice
Novák, Radomír ; Hynánková,, Eva (referee) ; Kriška-Dunajský, Michal (advisor)
The first section of this diploma thesis pursues an algorithm design of flood wave transformation in Excel software and its application afterwards. The software is used to design a small multipurpose reservoir. The algorithm covers consumption calculations of typical dam structures such as discharge structures, sluice planks, narrowed section of discharge pipes and safety spillways. The thesis also includes a mathematical model of water infiltration into the bottom of the inundation area and through the dam body. The last section of the thesis is dealing with an aesthetic integration of the whole structure into the local environment.
