Hydraulic roughness of water supply pipes
Náplavová, Eva ; Hofmannová, Lenka (referee) ; Ručka, Jan (advisor)
This bachelor’s thesis deals with hydraulic roughness of water pipelines, its consideration while making a hydraulic model and subsequent calibration of hydraulic simulation model. In the theoretical part literary review about current approach to hydraulic modeling of water mains and its possible future direction is carried out, as well as an overview of used roughness coefficients, computational formulas and possible approaches to calibration of the hydraulic model. In the practical part of the thesis, a matematical model of the supply main of the water mains network of Hvozdná is compiled and is followed by its calibration. The method of weighted least squares is used as an objective function. Optimization methods are used to minimize the value of the objective function and thus to determine the hydraulic roughness of supply main.
Risk analysis of the Hradek water supply system
Hofmannová, Lenka ; Svoboda,, Miroslav (referee) ; Ručka, Jan (advisor)
The diploma thesis is focused on risk analysis of water supply system in a small community. The WaterRisk project was solved by using tools of risk management including risk identification and quantification in the field of public water supply systems. Methodology and software for the risk management of water supply were evolved by using this project. In this thesis there is applied the methodology to the water supply system of Hradek village. The hydraulic analysis was performed for a thorough knowledge of water supply and its characteristic behavior. Risk analysis could be performed thanks to the knowledge of the entire system, its working and the most common faults. Analysis results are evaluated and compared for the water supply system which is consider like a system simple and complex. The corrective actions eliminate number of risks. These actions were proposed like a part of complex methodology. Further, there were determined optimal costs which corresponds with these corrective actions.
Hydraulic analysis of the Brno - Bystrc water supply system
Hofmannová, Lenka ; Tauš, Miloslav (referee) ; Ručka, Jan (advisor)
The bachelor’s thesis is focused on the hydraulic analysis of water storage Brno – Bystrc. The structure is devided into three parts. The first part is devoted to the research of used and applied methods and all available software tools, especially to the EPANET 2.0 programme, which was used during solving of given issue. The thesis also deals with description of specific campaign, which is the integral part of conducted analysis, and with the very hydraulic analysis, process and with the interpretation of acquired results outcome. The last part is dedicated to methodology of determining of the hydraulic capacity in chosen selected hydrants, which are not primarily intended for the fire protection, in the view of the CSN 73 0873 - Fire protection of buildings- Equipment for fire-water supply.
