Assessment of pressure conditions in the water supply network of the municipality of Ústí
Kuchař, Jakub ; Rajnochová, Markéta (referee) ; Ručka, Jan (advisor)
The bachelor's thesis is devoted to the hydraulic analysis of the water supply network of the municipalities of Ústí, Skalička and the settlement of Kamenec. The village is located in the Přerov district. The first chapter describes the theory of mathematical modeling and the basic relationships for calculation in pressure pipe systems. A quasi-dynamic hydraulic model of the entire area was created from the measured pressure values of the water supply network. The assessed values were displayed in the EPANET 2.2 simulation program. With regard to the character of the development in the municipalities, the pressure conditions in the area were assessed using the result. The last part of the work is dedicated to proposing measures to optimize pressure conditions and the resulting impact on the territory.

Hydraulic analysis of the Damnice water supply system
Bergerová, Marie ; Kopecký, Josef (referee) ; Ručka, Jan (advisor)
This thesis deals with hydraulic analysis of the proposed concept of connecting the Damnice group water supply systém to the Znojmo group water supply system. In firt part, the issue of drought and the related threat to the supply of drinking water are presented. The second part is focused on the basics of mathematical water supply network modelling and software program EPANET 2.2 used for modelling is described. In the practical part, the focus area is characterised and the process of building the model in EPANT 2.2 is clarified. A hydraulic analysis was processed for simulating four variants that represented the connection of different count of unicipalities to the proposed group water supply system. For individual variants, the optimal pipe dimension of the main supply pipe as well as the branching water pipes along the route were sought. In processing the results of the hydraulic analysis, pressure ratios, flow rates, water age in the water supply network and the reserve capacities of the water tanks were assessed.

Assessment and Optimization of the Hrubá Skála Water Supply System
Zikudová, Markéta ; Svoboda, Pavel (referee) ; Kučera, Tomáš (advisor)
The goal of this diploma thesis is to perform a hydraulic analysis of the existing water supply network Hrubá Skála – Radvánovice. The thesis is divided into several parts. The introductory chapter describes the purpose and objectives of the thesis. The second part presents general information about drinking water supply with a focus on pressure conditions on the network. The third part describes the mathematical modelling of water supply networks. The fourth part of the thesis describes in detail the individual objects on the Hrubá Skála – Radvánovice and Doubravice networks. It also provides information regarding the network recovery plan. The fifth chapter provides basic calculations and models the current state of pressures on water pipes in winter/summer and also according to information provided by the operator. The sixth chapter deals with five variants of the network recovery solution, where each variant is given a design, model and subsequent evaluation of this variant. At the end of the sixth chapter, all variants are compared with each other.

Assessment of pressure conditions in the water supply network of the village Poličná
Zuzaňák, René ; Libosvár, Dušan (referee) ; Ručka, Jan (advisor)
The bachelor thesis is devoted to the hydraulic analysis of the water supply network in the municipality of Poličná, Vsetín district. The introductory part of the thesis is devoted to the theory of mathematical modelling of the water supply network. A quasi-dynamic hydraulic model of the entire water supply network was created to determine the pressure conditions of the water supply network and then calibrated and verified based on the pressure measurements on the water supply network. The characteristic operating conditions of the water supply network were reflected in the simulation model of EPANET 2.2. Following the existing scale and type of development given by the current zoning plan of the municipality of Poličná, the pressure conditions on the water supply network of the municipality of Poličná were assessed using the results of the hydraulic analysis. The thesis includes proposed measures to optimize the pressure conditions for the prospective scale of development.

Modeling of water quality in the water supply network
Dukát, Petr ; Rajnochová, Markéta (referee) ; Ručka, Jan (advisor)
This thesis looks at water quality modelling in the water network, focusing on water age. The initial part of the work identifies the factors that lead to an increase in water age in water supply networks. The theoretical part of the work presents the mathematical relationships and logistical steps that software tools apply to simulate water quality indicators in a water supply network. In the practical part of the work, a hydraulic model of a water distribution system with a total length of 302,1 km was constructed. Measurement campaign was carried out to calibrate and verify created hydraulic model. Using this hydraulic model, water age for existing and possible scenarios was simulated. The results of the work have revealed parts of the water supply network containing high water age and are intended to encourage the progressive water distribution systems management philosophy.

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.
