Design of weir reconstruction
Němcová, Denisa ; Julínek, Tomáš (referee) ; Uhmannová, Hana (advisor)
This bachelor thesis deals with the design of the reconstruction of a solid weir on the Oslava river, in the town of Oslavany. The introduction describes the site of interest and the choice of a suitable design solution for its reconstruction. There are several types of movable weirs and fish ladders described theoretically. Further on in the thesis, the state of the objects on the flow and the state of the river basin of Oslava, in the area of interest, are described. Another part of the thesis deals with the design of a movable baying structure (a hollow flap). An impact assessment of the current and newly proposed weir on flow in the HEC-RAS program was carried out. The project also includes the design of fish ladder and an evaluation of the stability of the newly designed construction.

Reconstruction of the Hranice weir
Křenek, Tomáš ; Uhmannová, Hana (referee) ; Julínek, Tomáš (advisor)
The bachelor´s thesis is the modification of the existing weir structure in Hranice on the river Becva at river kilometer 38,300. The first part is a search dealing with the topic of weir structures. In the second part, the locality of interest is first described. Then there is a mention of the historical development riverbed of the Becva and the original fixed weir, which goes on to describe the existing weir structure. Subsequently, the individual reconstruction proposals were evaluated and the most suitable variant was selected, including the choice of the type of substructure construction, movable valve and the fish pass. Last but not least, hydrotechnical calculations were performed, witch also contain a partial calculation of the stability of the proposed structure.

Design of Inflatable Weir in Oslavany
Kocman, Tomáš ; Moronga, Jan (referee) ; Uhmannová, Hana (advisor)
This thesis describes the current state of the river Oslava in Oslavany design and reconstruction of the existing fixed weir in the affected location. As a best alternative reconstruction of the existing fixed weir reconstruction was chosen the hard threshold floating weir inflatable weirs. The next part of the thesis describes the proposed solution, and the last part of the thesis deals with the assessment of the proposed solutions.

Design of weir reconstruction in Oslavany
Němcová, Denisa ; Smelík, Lukáš (referee) ; Uhmannová, Hana (advisor)
This diploma thesis deals with a design of the reconstruction of a smixed weir on the Oslava river in Oslavany town. The introduction describes the site of interest and the the occurrence of ice events. There are several types of fish ladders described theoretically. Further on in the thesis there is desribed the state of the objects on the flow and the state of the river basin in the area of interest of Oslava river. Next part of the thesis deals with the design of a movable baying structure (a hollow flap) and fish ladder type bypass channel. An impact assessment of the current and newly proposed weir on flow in the HEC-RAS program was carried out. The project also includes the basin adjustment in overweir and an evaluation of the stability of the newly designed construction.

Gate weir design
Betlach, František ; Uhmannová, Hana (referee) ; Julínek, Tomáš (advisor)
The Bachelor Thesis deals with the study of the existing uncontrolled weir on the river Svitava in "Cacovice island" locality and with the design of a new gate weir structure. The first part focuses on the processing of data on the area of interest and the selection of appropriate design solution for the reconstruction of the weir, where there are described several types of adjustable shutters. At the end of this part the current condition of the buildings and the bed of the Svitava river in the area of interest is evaluated. In the second part, the Thesis deals with the design of the gate weir structure and its subsequent assessment. At first, the solid substructure and the height of the shutter is designed and assessed. Subsequently, the stilling basin is designed and in conclusion, the overall stability of the designed structure is assessed.

Using artifical neural network for ice phenomena prediction on the lower Berounka
Šebestová, Lucie ; Máca, Petr (advisor) ; Havlíček, Vojtěch (referee)
Ice phenomena on watercourses are commonly occurring effect in winter period. In most places do not cause any complication, but in certain places their occurrence is more frequent and in conjunction with forming ice phenomena into dangerous, as a break-up ice jam or a freeze-up ice jam, can lead to the formation of ice flood. Such places is affected lower Berounka watercourse in section Křivoklát - Vltava confluence. Occurrence and formation of ice phenomena depends on ice regime, which lower Berounka causing frequent problems. Ice regime is the interplay of many factors and ice phenomena are thus generally very difficult to predict because of strongly nonlinear relationships. Artificial neural networks excel in ability to learn on examples, in this case historical data, and ability to apply the knowledge gained on the data present and the future. This work uses multilayer perceptron neural network to realization of ice phenomena prediction based on historical flow and temperature data from the years 1887 - 1940 from the measuring station Křivoklát, which is a place of frequent occurrence of dangerous ice phenomena. The results provided by the learned neural network are comparable to the standard model used in modeling of ice phenomena. Obtained outputs confirmed the possibility of the successful application of neural networks in this area. Their use is possible as e.g. a part of information (warning) system or a system for predicting the occurrence of ice phenomena during winter season, which may lead to the alleviation of their impact on watercourse, surrounding area and residents.
