The study of selected sewer network in an urbanized catchment
Korytář, Ivo ; Habr,, Vladimír (referee) ; Raclavský, Jaroslav (advisor)
This paper deals the case study of the chosen sewer system in the village Starý Mateřov. The study solves passportization of sewer, what is the base for creating technical condition mainly for three selected sections. According to the results from the technical conditions of the three selected sections were suggested suitable options of redevelopment. The options are compared in financial way. The last chapter suggests two possibilities how to deal with the sewage. The first option consists of the transferring waste water to the waste water treatment plant in Pardubice - Semtín. The second option suggests building a new waste water treatment plant in Starý Mateřov. The options are compared in financial way.

Study of rehabilitation of selected part of sewer network
Dvořák, Pavel ; Helcelet, Marek (referee) ; Raclavský, Jaroslav (advisor)
The topic of this thesis is to create a study of the rehabilitation of the sewer network. The sewer system under assessment is located in city Znojmo, specifically Znojmo – city. In this case, rehabilitation is proposed in order to improve the functional operational properties of the sewer network and extend its service life. The work was divided into two basic parts, namely the Accompanying and Summary Technical Report. Three variants of solution were proposed. The first two variants are made as trenchless using a sanitation sleeve in the first one and a short sanitation sleeve in combination with a sanitation sleeve in the second. The third variant is made as an open excavation recovery. A description of the rehabilitation technology was carried out and the facts that each individual Option or what the three Option would bring up were defined. These three variants of the solution are assessed in terms of economic, technical and environmental impact.

Mathematical models of retention object of urban drainage
Pavlík, Ondřej ; Stanko,, Ing Štefan (referee) ; Pollert,, Jaroslav (referee) ; Prax, Petr (advisor)
This work deals with the use of 3D mathematical models of fluid in water management practice. Using 3D mathematical model was assessed retention tank Jeneweinova, which is situated on a sewer network of the city of Brno and is an important object of urban drainage. Retention basin designed to keep overflow from CSO chambers to Svratka and Svitavský náhon during storm events. Retention tank Jeneweinova is suitable for the assessment, because tank was designed bassed the Master Plan drainage of Brno using 1D mathematical model. Another factor was the physical model, which was build in LVV Vin FAST BUT. And finally, near the retention tank will be installed measurement on the sewerage network, which will be able to verify the results whitch has been predicted in this work. Mathematical model of retention tanks Jeneweinova was build in software FLOW-3D. FLOW-3D is a general purpose CFD (Computational Fluid Dynamics) software for flow of fluid in steady and unsteady mode and uses computational techniques to solve the equations of motion of fluids. This software is mainly used for the calculation of hydraulic fluids, gas flow and heat transfer simulations. Results from 3D mathematical model has been compared with the values in the physical and 1D mathematical model.
