River regulation with regard to the flood protection and revitalization
Kuneta, Tomáš ; Petrula, Lubomír (referee) ; Duchan, David (advisor)
The bachelor thesis is focused on the assessment of the part of the Svratka River. River Svratka flows through the city Brno. Area of interest is located in the southern part of Brno, specifically in the Brno - Modřice district. Hydraulic calculation is based on available geometric and hydrologic documents. The Svratka River Capacity Assessment was performed using 1D model in the HEC-RAS. Flood protection measure was designed based on the hydraulic calculations.

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.

River regulation and designing flood protection
Úlehla, Jiří ; Špano, Miroslav (referee) ; Duchan, David (advisor)
This thesis focuses on assessing the capacity of the river channel Becvy in the urban area of Prerov and design of flood protection for the city. Flood protection was designed in two variants. In the first variant dealt with recess bottom of the river. The second variant included a proposal of flood protection wall combined with a mobile barriers. The results are summarized in the synoptic maps.

Hydraulic assessment of surge waves in the Strekov weir reservoir
Stříž, Jaroslav ; Duchan, David (referee) ; Dráb, Aleš (advisor)
The main aim of the thesis is to assess the origin of surge phenomena, primarily surge waves at the weir pool Střekov, using the selected methodology. The paper is divided into several parts. There is a brief introduction to the problematics and research of possible solution methods, followed by a verification of these methods on a physical model and finally an application of a numerical method for an assessment of the chosen locality.

River regulation with flood protection
Zvolánek, Radim ; Špano, Miroslav (referee) ; Duchan, David (advisor)
This work describes the assessment of the capacity of the river Chrudimka on the river kilometers 87,837 to 93,173. The hydraulic computation was done for flow with periodicity of 10, 50 and 100. The calculation in the HEC-RAS program is described. Based on the results, flood protection is proposed. Flood protection is verified by a control hydraulic calculation The results are outlined in the drawing documentation

Revitalization of the Bílina river at Ervěnický koridor
Bartoš, Antonín ; Duchan, David (referee) ; Julínek, Tomáš (advisor)
This bachelor thesis is focused on revitalization of the tubular part of the Bílina river at Ervěnický koridor. The aim will be to remove the left pair of tubes and create a new riverbed, which will be naturally integrated into the landscape. Model and design is created in Autodesk Civil3D and AutoCAD. The capacity of the new riverbed was calculated using the HEC-RAS program.

Hydrodynamic model of the Odra river in the locality of Odry
Skokan, Jiří ; Duchan, David (referee) ; Dráb, Aleš (advisor)
The Bachelor's thesis deals with creating 2D hydrodynamic water flow model of Odra river in the locality of Odry (km 85,779 - 93,645). Using a numerical model HEC-RAS 6.2, hydraulic calculations of the peak flows of Q5, Q20, Q100 and Q500 were performed. The outputs were processed in the form of flood hazard maps, threat maps, written profile and drawing documentation.

Proposal of small earth dam
Stoklas, Jan ; Duchan, David (referee) ; Špano, Miroslav (advisor)
The subjekt of this bachelor thesis is the study of a small water reservoir in a particular locality. It consists of a text part and a drawing part. The text part contains brief summary of the issues of small water reservoirs, description of the locality, determination of design flow, needed hydrotecchnical calculations and design of expected technical solution. The drawings show the design of the dam, the combinated funtional object and the modified flooded area.

Study of extension of Bata canal waterway in Rohatec
Gulec, Jakub ; Duchan, David (referee) ; Dráb, Aleš (advisor)
The bachelor's thesis deals with navigating the last section of the Baťa canal in the section between the Rohatec weir and the Hodonín weir. The first part of the thesis describes the current state of the site of interest with its evaluation. The following sections describe the necessary building modifications. An integral parts of the thesis are drawings of the proposed solution of navigating this section of the waterway, hydrotechnical calculations and photo documentation from the site exploration.
