Study of the flood protection measures
Žiaková, Tereza ; Duchan, David (referee) ; Dráb, Aleš (advisor)
The bachelor thesis focuses on the assessment of the channel capacity and the design of flood protection measures on the Kotojekda river from the mouth to the Morava River up to river kilometre 3,200. The thesis includes hydraulic calculations using a 1D model. As a result, the proposed flood protection measure is in the form of raising the dikes to the design flow of Q20 with a safety elevation of 40 cm. This design, in combination with the previously developed dry reservoir design, provides protection of the area up to Q100 and protection of the surrounding area from flooding.

Revitalisation of a water channel
Voženílek, Vojtěch ; Havlíček, Tomáš (referee) ; Paseka, Stanislav (advisor)
The thesis deals with the proposal of improving the current condition of the Biskupice stream and its floodplain. The thesis is divided into theoretical and practical parts. The aim of the practical part is to get acquainted with the issues of watercourse revitalization and then transfer this knowledge into the design. The practical part focuses on a specific section of the Biskupice stream. It describes the site, includes hydraulic calculations in the HEC-RAS program, where the existing channel was first assessed and then the proposed one. Space is also devoted to the design of the pool system and accompanying vegetation. The work also includes drawing documentation.

River training of a small watercourse in the Morava River Basin
Filipi, Josef ; Duchan, David (referee) ; Uhmannová, Hana (advisor)
The aim of this thesis is to evaluate possible solutions of the river Svratka silting by the historical development from the 70s to the present. Part of this thesis is devoted to assessing the state of the watercourse in the area of interest, the assessment of flow capacity and design parameters that were used for the initial treatment course. The outcome of this thesis is to identify the causes of riverbed silting, creation of a conceptual design modification of the streambed and measures to limit the rate of canal silting. Custom design is supported by the hydrotechnical calculations.

Flood protection of the municipality Březová nad Svitavou
Cetkovská, Lucie ; Vysloužilová, Lucie (referee) ; Uhmannová, Hana (advisor)
The diploma thesis is focused on the assessment of the stream and the proposal against flood risk in the location of town Březová nad Svitavou. The stream Svitava flows under administration of Povodí Moravy. s. p. The stream Svitava flowing through urban area, has a high potencial flood risk. The current situation of a section of the stream is assessed based on defined data and personal inspection. On the stream, there were provided the measurements by the method of HEM. Capacity of the stream along with the objects for the particular section were calculated in the software HEC-RAS. Based on the results, there have been designed the flood protection. The final design was verified by the calculation in the program HEC-RAS.

Design of boulder chute reconstruction
Zahradníková, Lenka ; Julínek, Tomáš (referee) ; Uhmannová, Hana (advisor)
The aim of the thesis is to design a boulder chute reconstruction for the Rožnovská Bečva watercourse at 10,865 river kilometers. The design proposes adjustments of the watercourse of the total length of 642,8m. The thesis also includes designed parameters for the boulder chute reconstruction at 10,865 river kilometers. The current watercourse capacity was assessed using the HEC-RAS 4.1.0 software and a computational model was made of the parameters of the chute. The capacity of the newly designed riverbed was verified using HEC-RAS 4.1.0. Based on the calculations, the boulder chute reconstruction was designed.

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.

Proposal of nature-friendly measures on a selected watercourse
Lach, Radek ; Smelík, Lukáš (referee) ; Uhmannová, Hana (advisor)
The main aim of the diploma thesis was an assessment of the current state of the Svratka watercourse flowing largely through the urban area of the town of Jimramov, especially the adjacent parts of Sedliště and Benátky, and to a lesser extent through the suburban area below the municipality. The given section is 2,6 km long with the beginning in the river kilometer 131,10 and the end in the river kilometer 133,70. The capacity of flows and objels in the given period has been assessed (bridges, weirs, steps, etc.). Calculation water surface profiles have been made by usage of the 1D mathematical model HEC-RAS. Part of the work was to determine the current level of flood protection on the stream. The assessment is based on personal visit and photos taken as rekord. The thesis was complemented with hydroecological monitoring of the stream channel – the HEM analysis 2014. The final phase of the work deals with the conceptual design of a nature-friendly flood control measure to increase the protection of the adjacent area and improve the condition of the watercourse. Progress of individual levels and measures are based on hydrotechnical calculations.

A draft amendment selected section of of the watercourse
Vyplel, Adam ; Blahuta, Jaroslav (referee) ; Šlezingr, Miloslav (advisor)
The bachelor thesis focuses on the draft amendment of the selected section of the Veverka watercourse in the cadastral area of Brno-Bystrc in the km 0,632 to 0,918 of watercourse. The adaptation is mainly done as a draft for the stabilization of damaged banks by means of stone retaining wall, wooden pole fencing, stone riprap and gabions. The suitability of the given measures was determined on the basis of the current state of the watercourse. In the chosen section there is a sedimentation reservoir with a boulder chute that has been subjected to an assessment of the stability of the slope surface. Then the HEC-RAS program is used to verify the flow capacity of the whole flow channel for the one-year flow Q1 condition. Subsequently, the vegetation accompaniment and the coastal vegetation of the selected section of the watercourse were designed in order to naturally connect the watercourse to the surrounding forest vegetation.

River regulation and design of flood protection
Gřegoř, Adam ; Julínek, Tomáš (referee) ; Duchan, David (advisor)
The bachelor’s thesis deals with designing flood protection on the watercourse Velička (tributary of the river Bečva), which is situated in the area of Hranice municipality. The flow modelling was done as 1D surface water HEC-RAS model. Two options of flood protection were designed based on the size of the flood areas that occured during flood flows Q5, Q20 and Q100. The first option did not consider the usage of Lhotka dry pond. The second option considered the usage of Lhotka dry pond, which was designed in the study made by AgPOL s.r.o. firm to the north of Hranice and which transforms flood flows. The result of the bachelor’s thesis are maps of flood areas that occured during the flood flows Q5, Q20 and Q100 after the implementation of flood protection options. In conclusion, the suitability of the flood protection options is evaluated.
