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.

River management with regards to flood protection and revitalisation
Pastorková, Nikola ; Petrula, Lubomír (referee) ; Duchan, David (advisor)
The theme of this bachelor thesis is the hydraulic assessment of water flow capacity in the river kilometer 12,227 – 17,979, at flows Q5, Q20 and Q100 using 1D and 2D model in the program HEC-RAS 5.0.7. From the results of the overflows, flood protection measures have been proposed in two locations in the urban area and the revitalization of the stream has been also proposed. Furthermore, a hydraulic verification of the flood protection design took place.

Analysis of flood situation on selected part of river
Štěpánová, Markéta ; Smelík, Lukáš (referee) ; Duchan, David (advisor)
The thesis deals with an evaluation of flood situation at the area of the river Svitava in Brno throughout three different flows Q5, Q20 a Q100 and that proposes a possible solution for flood protection. Current state of the river stream is evaluated through hydraulic calculation combining 1D and 2D numerical modelling of flow rate with the use of HEC-RAS software.

River revitalization
Hrušková, Gabriela ; Julínek, Tomáš (referee) ; Duchan, David (advisor)
The Kyjovka River was negatively impacted in previous years as a consequence of erroneous technical alterations. The town of Kyjov, situated along the river, aims to integrate the watercourse into the landscape and improve its capacity. The site under consideration is located within the urban district of Boršov, where the town acquired multiple parcels of land for the purpose of revitalizing the watercourse. To ensure the revitalization of the watercourse, a comprehensive description and hydraulic assessment of its current condition were conducted. The results served as the basis for formulating multiple alternative solutions.
