River regulation and flood protection
Pechová, Kamila ; Petrula, Lubomír (referee) ; Duchan, David (advisor)
This bachelor thesis is focused on a proposal for adjustment of a flow with a consideration of an anti-flood protection and a revitalization the Svitava river in Bílovice nad Svitavou. Based on a course of the height of the water level discovered from a computational model from the HEC-RAS program is designed an anti-flood protection of the flow and this way the spilling of the river from an intravilan is prevented.

Proposal measures at upper reaches Svratka River
Klepárníková, Radka ; Smelík, Lukáš (referee) ; Uhmannová, Hana (advisor)
The diploma thesis deals with the proposal of measures on the Svratka stream in the cadastral area Český Herálec and Herálec na Moravě. The aim of the diploma thesis is to propose appropriate flood protection in the Herálec urban area and to elaborate proposals of nature friendly measures outside the municipality’s built up area, which will enable the renewal of the ecological functions of Svratka in the spring area. In the diploma thesis the assessment of the current state of the watercourse in the analyzed locality was caried out and also the assessment of the capacity of the watercourse and the objects on there. Furthermore, the flood levels and its areas were determined. Hydraulic water flow calculations were performed using the 1D and 1D/2D numerical model. For calculation, HEC-RAS 5.0.3 was used. When processing a 1D/2D numerical model, a manual describing the progress of work in the HEC-RAS 5.0.3 program was also created. On the basis of the results from the numerical model, a proposal for flood protection measures in the urban area and nature friendly measures in the extravilan was carried out.

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.

The Třebařovský creek. Assessment of small scale river.
Pikhartová, Karolína ; Petrula, Lubomír (referee) ; Julínek, Tomáš (advisor)
The objective of this thesis is to assess current condition of the small river Třebařovsky potok situated in partly urbanized area. The reach of interest is in km 0,000 to 4,320. Assessment involved evaluation of the channel capacity and stability of the river bed. Assessment was realized by solving the flow characteristics for series of discharges. Based on the results of the current conditions the proposal of the river training and other remediation measures was done.

Reconstruction of gate weir on the river Bystřice in Kunčice
Svatoš, Petr ; Neumayer,, Oldřich (referee) ; Duchan, David (advisor)
This thesis is about reconstruction of existing floodgate weir on the river Bystřice in river km 17,650. In actual state (2017) there is floodgate weir with four independent flow fields. This construction is inappropriate in the locality due to the capture of floating debres on the guiding profiles of the weir boards at higher flows, which reduces the flow capacity of the weir profile and consequently the flow over banks of the river Bystřice into the village of Kunčice. As a solution, the reconstruction was chosen as a movable structure with automatic water level control – rubber weir. This proposal is then compared to the previous investor's proposal on the economic, hydraulic and operational aspects.

Proposal of flood protection on the river in the basin of the Morava
Salingerová, Lucie ; Smelík, Lukáš (referee) ; Uhmannová, Hana (advisor)
The main aim of the thesis is an appraisal of the stream Oslava which belongs to the Náměšť nad Oslavou region with the focus on flood control of the town. The thesis asseses current state of the stream with respect to the state of riverbed, bulwark of the stream and evaluation of the capacity of the stream channel. Calculation water surface profiles have been made by usage of the 1D mathematical model HEC-RAS for selected N-year flows. The capacity of flows and objects in the given period has been detected. There is also a map of the water runoffs included and possible solutions of how to protect the area surrounding the stream are proposed. The thesis was complemented with hydroecological monitoring of the stream channel - the HEM analysis 2014.

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.

River trainning - The Luha River in Jesenik upon Odra
Tkáč, Matěj ; Tureček, Břetislav (referee) ; Julínek, Tomáš (advisor)
The object of this Master`s thesis is the river training of the Luha river in Jeseník nad Odrou. The thesis is divided into several chapters. In the theoretical introduction, the problems of the sediment flow regime are discussed. Moreover, it deals with the questions associated with the roughness in open channels and adjustment of riparian zones. As a part of the overall proposal of the flow adjustment, the hydraulically most suitable cross section in cunette is proposed. It is done with respect to the desired velocity ratios in the profile. Since the new cunette shape was established, the adjustment of vertical alignment was proposed. The thesis also contains the capacity assessment of the existing channel. Design of adjustment of flood protection measures includes mainly spatial rearrangement and increase the crest of levees with respect to the local conditions. The thesis also suggests the placement of vegetation in the riparian zones. Furhermore, the work deals with problems arising from the flow adjustment considering applicable laws and regulations of the Czech Republic. In the case of project implementation, it is necessary to evaluate these problems independently.

Assessment of the River Regulation Jihlavka in Jihlava
Salingerová, Lucie ; Šlezingr, Miloslav (referee) ; Uhmannová, Hana (advisor)
The aim of my bachelor´s thesis is the assessment of the Jihlavka River within the boundaries in the town of Jihlava after 11 years, since a renovation flow. The bachelor´s thesis evaluates the current state of the watercourse Jihlavka in the administrative territory of the town of Jihlava from the perspective of the assessment of fortifications of the streambed and the existing capacity of the watercourse. Calculation water surface profiles have been made by usage of the 1D mathematical model HEC-RAS for selected N-year flows. The capacity of flows and objects in the given period has been detected. A part of my thesis is a draft of measures to improve the current state of the channel as well as assessing opportunities to increase flood protection of the adjacent territory.
