Evaluation of Flood Protection of Újezd u Brna
Lehotská, Lívia ; Jelínková, Iva (referee) ; Jandora, Jan (advisor)
The aims of the bachelor thesis is evaluation of flood protection of town Újezd u Brna and propose the increase levees of the Litava river or reduction levees under the city and realize the water from the river to inundation. The thesis will be transferred to the calculation using the HEC - RAS. The conclusion will be evaluated both proposals for protecting the city.

Assessment of runoff conditions on flow in the cadastral area of Dašice
Janovská, Michaela ; Vysloužilová, Lucie (referee) ; Uhmannová, Hana (advisor)
This thesis is aimed at assessment of drainage conditions at the river Loucna in the cadastral area of Dasice. The examined section is 3,88 km long and runs through out of the city and in the city of Dasice. On the left bank of the river there are several historic buildings that are potentially at risk for 100 years of flow. Capacity assessment is performed using the 1D mathematical program HEC - RAS in which the flow model is created and the calculation of the flow rates for individual N - year flows. On the basis of the results of the program is conducted conceptual desing of flood protection measure. At the same time is conducted conceptual desing of fish ladder on the weir and a sluice closure on the intake for the race.

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.

Flood control measures in the Nectava River basin
Boháč, Ondřej ; Menšík, Pavel (referee) ; Starý, Miloš (advisor)
This bachelor’s thesis deals with the flood control in the basin Nectavy. The aim is to assess the need enhance flood control in the basin. The work is divided into two parts, the first part deals with own description of the basin and the second part with data processing in programs ArcGIS and Hydrog. The description of the basin consists of a personal acquaintance with the basin and its surroundings, interview with residents of communities located along the river and description of geographic factors in the basin. After obtaining all necessary informations will be basin schemed in the program ArcGIS where it will be divided into smaller sub-basins which will require for further work. The output from the previous step is used for processing in the program Hydrog, to work in this program is also needed to calculate the replacement intensity of rains. Simulation in the program Hydrog are obtained critical period of rains and set N-year flows. In the end the obtained values of peak flows are compared with the actual flows and identifying critical points are assessed for possible flow and flood.

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.

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.
