Rainfall data in urban drainage
Mrázek, Jan ; Prax,, Petr (referee) ; Raclavský, Jaroslav (advisor)
The aim of the bachelor thesis is to process knowledge from measured precipitation data and aplicating this knowledge on methods of prepration of a hydraulic sewage network model of Znojmo city. The first part is a research in the field of interest, being sewage network and precipitation data processing. The detailed procedure of modeling and quantification of the measured data is explained in the practical part of the thesis. After that the process of inputting the data in to a hydraulic model in MIKE URBAN, the program which draws topological data from GIS (retained by VAS a.s. as the investor) and exports the final model into a SWMM enviroment. At last but not least the thesis focuses on schematization of the objects situated on the sewage network, such as relief chambers. The result is a noncalibrated and nonverified model of a part of sewage system of the Znojmo city and systematically organized measured critical rains. This model is going to be optimized after this thesis is finished, thus also calibrated and verified.

Dvorský, Petr ; Prax,, Petr (referee) ; Hluštík, Petr (advisor)
This thesis deals with the monitoring of the sewerage system in the city of Brno. In the research part, there is made an overview of the most used measuring equipment for the monitoring of the sewerage system – level meters, flowmeters, automatic samplers. The practical part is devoted to the monitoring of the sewerage system in Brno for partial evaluation of the benefits of the project „Reconstruction and completion of sewerage in Brno“, realized in 2012 – 2014. Measuring campaign has taken place from June to October 2017. In the course of the work, the instalation of measuring equipment and the collection of measured data was done. After finishing measuring campaign, the data were evaluated from different aspects – the number of overflows, the quantity of overflowing water, the dilution ratio and the quantity of discharged pollution. Then, the hydraulic and construction technical assement of the pipelines of sewer network and overflow chambers and assements of the quantity of the rainwater were made. The results of the evaluation were compared with the results of the previous monitoring campaingns and with the data obtained before the project has been realized. Based on this, the benefit of the project was determined.

The study of rehabilitation alternatives selected of sewer network
Novák, Tomáš ; Hluštík, Petr (referee) ; Raclavský, Jaroslav (advisor)
The topic of my bachelor thesis is an evaluation of alternative solutions in terms of a reconstruction of a section of a sewage system using trenchless technology. For this purpose, the work is split into two parts. The main goal of the first, theoretical part is an introduction into trenchless technology and its description. The focus is particularly put on methods used for a new construction, eventually a number of renovation methods, which keep the construction of the rehabilitated conduit. Besides the description of the individual methods, the first part also contains their technological procedure, and their positives and negatives. The second part further uses the newly gained knowledge to solve a specific case on the Veveří street in Brno city. As the reconstructed section of the sewage network is in the built up area of the city, the primarily reflected possibility for the reconstruction in the work is trenchless technology.
