The development of a method for evaluation of the green roofs' retention capacity
Herůfek, Marek ; Hejduk,, Stanislav (referee) ; Žák, Antonín (advisor)
This diploma thesis deals with the development of methods for evaluating retention features of green roofs. For the purpose of this thesis, a rainfall simulator was designed and various types of precipitation were examined. The thesis is divided into two main parts: a theoretical part and a practical part. In the theoretical part, the importance of water retention on green roofs is discussed. In addition, a physical theory related to this topic is included and various rainfall simulators used for scientific experiments in the Czech Republic and abroad are described. The practical part deals with the measurement of droplet size and rainfall simulator design. In this part, the process of measuring the flow and the intensity of rainfall by using scales, flow meter and rain gauge is described. For this purpose, a datalogger was developed by the Faculty of Eletrical Engineering in Brno. Finally, the results are sumarized and recommendations on how to conduct the research in the future are provided.

River adaptation with Civil 3D and HEC-RAS
Filípková, Monika ; Julínek, Tomáš (referee) ; Duchan, David (advisor)
This bachelor thesis deals with the evaluation of the current state of the selected section of the Morava river around the city of Olomouc and the subsequent modification and desing of the flood protection. In the first step, hydraulic flow verification using CIVIL 3D and HEC – RAS is performed. Based on the results of the 1D model, proposal river adaptation is then also executed with the aim to incerase the flow capacity and to reduce the water effusion.

Assessment of runoff conditions on flow in the Morava river basin
Holá, Lucie ; Niklová, Věra (referee) ; Uhmannová, Hana (advisor)
The diploma thesis deals with the design of nature close to the flood protection of the city Prostějov at the confluence of the watercourses Romže and Hloučely and the flow Valova (Romže). In canculations there was solved capacity of individual sections and canculation of levels for one-year, five-year and twenty-year flow. For canculations there was used one-dimensional mathematical model HEC-RAS 5.0.3. Determination of roughness of bottom and slopes was based on personal visit. The result of this diploma thesis is evaluation of current state and proposal of a nature close to the flood protection in the individual streams in the city Prostějov. The thesis contains the calculation part and the drawing part documenting the proposed measure.

River regulation with regard to the flood protection and revitalization
Bohatý, Martin ; Julínek, Tomáš (referee) ; Duchan, David (advisor)
This bachelor thesis focuses on the evaluation of the current state and proposal of the river Bobrava, which can be found in the district of Brno-venkov. Among other things, it flows through the municipality of Želešice, our locality of interest. The work is divided into theoretical and practical parts. The theoretical part is devoted to water flow in an open channel and basic calculation methods. The practical part describes the site of interest, including hydraulic calculations in the HEC-RAS program and the proposed treatment itself. Hydraulic verification of the design and its evaluation is also an integral part of the work.

Revitalization of the selected section of the River
Bakala, Filip ; Petr, Pelikán (referee) ; Šlezingr, Miloslav (advisor)
This thesis deals with revitalization of the selected part of river Drevnice. Main scopes of the work are proposals of fish passages through migration barriers. The work is conceived on four levels. The first of them is dealing with the general characteristics of selected segment and with description of objects on watercourse. The second level is dealing with revitalization, where the basic information about migration and efficiency of fishes are described. In this chapter basic distribution of fish ladders is included. In third part, which is the most comprehensive, I design a boulder fish ramp and bypass channel. The last chapter contains drawings documentation of watercourse Drevnice and my own proposed revitalization elements.

Proposal of the water divider on the river Romže
Blaha, Josef ; Zedníček, Jiří (referee) ; Uhmannová, Hana (advisor)
The diploma thesis deals with the design of the water divider near Prostějov on the Romže River. Divider flows will be transferred into the Hloučela River. Within the thesis, hydraulic calculations of the side spillway were solved according to Bürgel, Pavlosky, Engels, Musterle, Kunštátský, Hager and energy solution methods in the Microsoft Excel spreadsheet and by using the HEC-RAS program as well. The calculations were compared to each other. Geometry of the relief water divider on the Romže River and the related buildings was designed based on the performed calculations. The required function of the relief object is guaranteed by manipulation of designed sluice gate. The study includes the text part with the calculations and the drawing part documenting the implementation of the designed measures.

Design of Inflatable Weir in Oslavany
Kocman, Tomáš ; Moronga, Jan (referee) ; Uhmannová, Hana (advisor)
This thesis describes the current state of the river Oslava in Oslavany design and reconstruction of the existing fixed weir in the affected location. As a best alternative reconstruction of the existing fixed weir reconstruction was chosen the hard threshold floating weir inflatable weirs. The next part of the thesis describes the proposed solution, and the last part of the thesis deals with the assessment of the proposed solutions.

2D numerical modelling of shallow water flow in floodplains
Monhartová, Pavlína ; Sýkora, Lukáš (referee) ; Dráb, Aleš (advisor)
The aim of the thesis is hydraulic computation of shallow water flow in floodplains with using 2D numerical modelling. Processing river is Dyje in the south of Moravia in location Břeclav. For model creation is necessary to know the software, accumulate input data and prepare model input parameters. Output data are process to form of maps water depths and maps water flow velocities.

Regulation of the river
Varga, Tomáš ; Pilařová, Pavla (referee) ; Šlezingr, Miloslav (advisor)
This bachelor thesis deals with the evaluation of current state of selected part of the river and deal with regulativ of river. The work is conceived on four different levels.The first on eis describesing general characteristics of the selected selection. Second concern calculation of capacity and following river regulativ. Next part contains proposal of vegetation belt. The last part is about drawing of current state and also river regulativ features.

The revitalization project of the selected section of the watercourse
Skřížala, Lukáš ; Blahuta, Jaroslav (referee) ; Šlezingr, Miloslav (advisor)
Bachelor thesis deals with revitalization in the selected section on the watercourse Ondřejnice. Purpose of the revitalization is especially the removal of the migration obstacles creating conditions for the natural development of the trough, without any need of standard maintenance by the flow manager. In the bachelor thesis have been replaced some stone steps by the boulder slip, the wooden gradients have been replaced by some new wooden steps with holes for the migration of animals. Then were in the watercourse designed some Fish shelters. At the places where the gradient adjustment will take place, will be designed a new vegetation accompaniment. By the design of the revitalization measures there will be no worsening of the drainage ratios.
