Study of river restoration measures of suburban watercourse
Šebesta, Radek ; Veselá, Olga (referee) ; Králová, Helena (advisor)
This diploma thesis deals with the problem of river restoration. Selected watercourse, which was inappropriately technically modified, had been mapped in detail and land use map was compiled. The watercourse was divided into sections, which were described in detail and assessed for suitability for restoration action. The new nature-friendly channel was designed on the selected section of the watercourse. Technical graphic documentation was designed.

Flood protection of the municipality Brantice
Zahradníková, Lenka ; Niklová, Věra (referee) ; Uhmannová, Hana (advisor)
The thesis is concerned with the design of a flood protection for the Brantice municipality, a part of which is an adjustment of the Opava river stream bed, specifically kilometer 77,6554 to 78,7020 and, moreover, a design of a reconstruction of the weir at kilometer 78,340. A capacity assessment of the original stream bed in the built-up area and its surroundings is a part of the thesis, as well as a measure to increase the stream capacity and a design of a boulder chute with a water gate, which replaced the original weir. The program HEC-RAS 4.1.0. was used for the stream capacity calculations.

Proposal for the nature friendly measures on the river Bobrava
Mláděnka, Jakub ; Smelík, Lukáš (referee) ; Uhmannová, Hana (advisor)
The aim of the diploma thesis is to describe and evaluate in detail the current state of the Bobrava river in the interest section – river kilometer 1,832-5,743. Part of the work is to assess the capacity of the river flow and the objects connected with it and find the class of an actual safety at village Zelesice. The calculation of the flow rate is performed by using the 1D mathematical model HEC-RAS for selected N-year flows. On the basis of the results of the flow rate, it is made the idea of natural freindly flood protection before the value of the 20-year flow. The result is two variants of river basin adjustment, when each one is leading to make Zelesice safer place and to improve the current state of the river Bobrava.

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.

Assessment of the water flow in the Odra river basin
Mláděnka, Jakub ; Vysloužilová, Lucie (referee) ; Uhmannová, Hana (advisor)
The aim of the bachelor thesis is to describe and evaluate in detail the current state of the Luha river and the objects connected with it, in the interest section – river kilometer 0.000-2.853 in the cadastral area of the Jeseník nad Odrou. Part of the work is to assess the capacity of the river flow in the locality and to propose ideological measures that would increase it to the design value of the 20-year flow. The calculation of the flow rate is performed by using the 1D mathematical model HEC-RAS for selected N-year flows. On the basis of the results of the flow rate, the assessment of the capacity of the channel and the objects in the solved section, two variants of continuous river basin adjustment are proposed to improve the current state of the channel and to increase the flood protection of the neighboring area.

Determination of floodplain in Kyjovka river at km 71 to km 74
Kašpar, Tomáš ; Roušar,, Ladislav (referee) ; Zachoval, Zbyněk (advisor)
The diploma thesis discusses the current status of watercourse Kyjovka and a proposal for appropriate protection measures of the territory. The selected section starts at river-km 71,338 and ends at river-km 74,443. The selected part of the watercourse runs through the town of Koryčany. This thesis examines the selected section of Kyjovka split into two subsections. That allows for detailed presentation of several proposed appropriate measures to be applied at critical spots in the selected subsections. The calculation of the watercourse model and its capacity with the water level progresses for selected N(y.o.) flow rates were processed in HEC-RAS5.0.1. program. Proposed flood protection measures are incorporated in the drawings.

Revitalization of the selected section of river "Hartmanický potok"
Samková, Aneta ; Gernešová, Lenka (referee) ; Šlezingr, Miloslav (advisor)
Diploma thesis deal with revitalization Hartmanice river in district Svitavy. Section of interest is on 0,400 – 1,234 of river km. Part of this thesis is also rating current condition of stream and his vegetation accompaniment. Rating was made on base of reconnaissance terrain, my own measurement and photo documentation. In diploma thesis was design some revitalization steps: stabilization sink with wooden sills and stabilization slopes by using willow fences and similar precautions. There was designed total change of flow trend. Rating of current condition and condition of modified stream was made in software HEC-RAS.

Assessment of the Possibilities The Revitalization of a Watercourse Osoblaha – Reach I
Mitana, Petr ; Musálková, Ivana (referee) ; Uhmannová, Hana (advisor)
Diploma thesis deal with the issue revitalization of water stream. Assessment and design of revitalization is done for watercourse Osoblaha, situated in the cadastral territory Osoblaha nad Studnice by Osoblaha. In diploma thesis were designed several of revitalization measures such as stone backfill, willow fence, groyne, casting willow cuttings to supplement the vegetation on river‘s banks, fish shelter and wirestone baskets (gabions). In the given section was designed pool and also was there designed boulder slip, which will replace present downflow step. After designing was made hydrotechnical calculations to demostrate preservation runoff conditions of present stream condition.

Assessment of the Possibilities The Revitalization of a Watercourse Osoblaha – reach II
Vysloužilová, Lucie ; Peterek, Lumír (referee) ; Uhmannová, Hana (advisor)
This thesis deals with examining the possibility of revitalizing the watercourse Osoblaha. It flows through the cadastral territories of municipalities Bohušov, Osoblaha and Kašnice u Bohušova. In this thesis there will be proposed a measure to increase biodiversity of the flow. The trough will be loosened in appropriate segments, oxbow lakes and ponds will be designed. Also the bank shelters for fish stock will be suggested. For slope stabilization will be used reinforcement of fresh willow fences. Impermeable shoots or disintegrating oxbow lakes will be projected in the straight sections of the flow.

The Revitalization of a Small Watercourse
Svědínková, Renáta ; Moronga, Jan (referee) ; Uhmannová, Hana (advisor)
My diploma thesis deals with the issue revitalization of a small stream. Assessment and design of revitalization is done on Kuřimka stream which flows through the cadastral territory of the Moravian Knínice - Chudčice - Kníničky. In the diploma thesis were designed several of revitalization measures: stabilization of longitudinal tilt with the use of stone steps in the bottom and wooden thresholds, sedimentation reservoir for capturing sediment and slope stabilization using willow fences and gabions. Proposal of revitalization measures does not deteriorate runoff conditions.
