Stochastic modeling of water consumption in the water supply network
Kopecký, Josef ; Tureček,, Jan (referee) ; Ručka, Jan (advisor)
This thesis deals with stochastic water demand modellling in the water supply network. In the opening section, a research is created, where two different approaches to stochastic modelling of water consumption are presented. The practical part describes the creation of a deterministic hydraulic model and its calibration. Generated stochastic water demand patterns with a small time step of 1 minute, are then inserted into this model. Each household is assigned with a unique water demand pattern. Then a hydraulic analysis was done. A comparison of deterministic and stochastic approaches is presented at the end of the thesis. The comparison shows, that small-time step modelling does not have a big impact on the pressure ratios in the water supply network, but has a huge impact on the maximum flows and speeds occurring in links of the hydraulic model.

Hydraulic analysis of the water supply network of the municipality of Ostopovice
Jaroš, Zdeněk ; Sucháček, Tomáš (referee) ; Ručka, Jan (advisor)
The theses focuses on a hydraulic analysis of a water supply network of a village called Ostopovice, located in South Moravia. Theses presents a detailed quasi-dynamic hydraulic simulation of the water supply network based on own consumer field survey. Subsequently, the assembled model was calibrated and verified by hydraulic data measured on the water supply network. The model was made to simulate characteristic water supply system operating conditions. Using the hydraulic analysis results, the theses assesses network pressure conditions with regards to the existing building range and type, taking into the account the extent of expected house development of the area. The work concludes with a proposition for measures leading to the water supply network pressure conditions optimization.

Optimization of the Water Supply Network of Počátky Town
Pavelka, David ; Netušil, Lukáš (referee) ; Kučera, Tomáš (advisor)
This diploma thesis focuses on the optimization of water supply system in the town of Počátky. It describes the process of creating a mathematical model needed for the hydraulic analysis, which was used to assess the water supply system Počátky. This thesis task is to apprise reader, with a basic distribution in the drinking water supply, how to proceed in collecting data on hydraulic analysis requirements and using tools and means used in hydraulic analysis. Conclusions are processed variants for possible optimization of water supply system Počátky.

Hydraulic analysis of the Velký Beranov water supply network
Kopecký, Josef ; Remeš,, Bronislav (referee) ; Ručka, Jan (advisor)
The thesis is focused on hydraulic analysis of water supply network of the Velký Beranov in Jihlava district. A detailed quasi-dynamic hydraulic model of the water supply network was created, and then subsequently calibrated and verified on the basis of measurement of hydraulic quantities on the water supply network. The least squares numerical method was used to calibrate the model. The simulation model illustrates behavior of the water supply network during the characteristic operating conditions of the water supply. The follow-up analyzes carried out assessment of the pressure ratios with respect to the existing and future development given by the zoning plan.

Impact of pressure condition on water consuption in water distribution network
Straňák, Petr ; Sucháček, Tomáš (referee) ; Tuhovčák, Ladislav (advisor)
The diploma thesis deals with effect of pressure conditions in the water supply network on consumption of drinking water. The introductory part describes how pressures affect water consumption and six studies from different countries carried out on real network are presented. Further, the work is devoted to other factors influencing water consumption and distribution of domestic water consumption. The practical part deals with the laboratory measurement of the influence of pressure change on tested discharge fittings for flowing and dripping water. The results are also expressed in annual costs and a method is presented how the effect of pressure change can be quantified if we know the average daily consumption and its distribution.

Assessment of drinking water consumption in the water supply network of the Valašské Meziříčí
Fučík, David ; Libosvár, Dušan (referee) ; Ručka, Jan (advisor)
This diploma thesis deals with the analysis of the time series of drains from the water reservoir and evaluation of the minimum night flow in the water supply network of the town of Valašské Meziříčí. In the theoretical part of this thesis were elaborated research of Czech and foreign literature focusing on drinking water consumption analysis, measurement and evaluation of minimum night flow and methods of determination of water losses in distribution systems. The practical part includes analysis of water outflows from reservoirs, evaluation of minimum night flow and determination of basic water loss indicators for selected district metered areas of the network. The above-mentioned water supply network is operated by the Vak Vsetín, a.s.

Design and Operation of Water Disinfections Plants
Krupicová, Simona ; Rajnochová, Markéta (referee) ; Kučera, Tomáš (advisor)
In the first part of my bachelor thesis I deal with individual disinfectants used for hygienic supply of drinking water based on chlorine and without chlorine. Then I mention the operation without chlorine disinfectants. In the second part of this thesis I describe individual plants using various disinfection methods and at the end of the thesis I compare these methods and use it in practice.

Technical Assessment of Water Supply Infrastructure
Hos, Lukáš ; Kučera, Tomáš (referee) ; Tuhovčák, Ladislav (advisor)
This bachelor‘s thesis is about condition assessment of water supply infrastructure. First part is about legislative demands on condition assessment and about methods used abroad to asses water supply infrastructure. Second part of this thesis is about application TEA Water. It is described how it works and it is used to condition assessment of fictional water supply infrastructure and choosen objects of real water supply infrastructure.

Optimisation of Pressure Condition in water Distribution Networks
Straňák, Petr ; Sucháček, Tomáš (referee) ; Tuhovčák, Ladislav (advisor)
The bachelor thesis deals with pressure in the water distribution network. The introductory chapter describes legislative requirements for network pressures and means of network auditing. The following chapter deals with the optimization of pressure conditions in the water distribution network, describes the positive and negative aspects of pressure optimization, illustrates ways of influencing pressures, and briefly analyzes existing case studies from abroad. In the final chapter, with the help of the EPANET 2.0 program, pressure optimization is performed on the fictional network.

Hydraulic analysis of the Tvarožná water supply system
Trněná, Eva ; Sucháček, Tomáš (referee) ; Ručka, Jan (advisor)
This bachelor thesis deals with the hydraulic analysis of the existing water distribution system of Tvarožná village. The thesis is divided into several parts. The first part introduces the purpose of the work. The second part focuses on mathematical modeling of water distribution system, hydraulic analysis of water distribution system, describe Epanet 2.0 software that was used for modeling and review the current research on mathematical modeling of water distributions systems. The third part of the thesis analyzes in detail the studied area and describes drinking water distribution to the municipality. The fourth part describes the measuring campaign in the locality and its evaluation, which was subsequently used for the model construction. The fifth part describes the input data and the procedure for the model settings in the software Epanet 2.0. The results of the hydraulic analysis are the pressure conditions in the water distribution network, which are compared to the actual valid legislation. Also the hydraulic capacities of the fire hydrants and their location in the municipality are compared to the standard requirements.
