Lateral recirculation zones of flow in approach channel of weir
Korálová, Nikola ; Pařílková, Jana (referee) ; Zachoval, Zbyněk (advisor)
The bachelor’s thesis is divided in to the literary research and practical part. The content of the literary research is the issue of side contracted weirs, where occurs side contracted flow. The sudden change of the channel width and formation of upstream wake have direct influence on value of discharge coefficient. There are described types of the weirs, ways of computing discharge and discharge coefficients which are influenced by contraction. In the practical part of thesis is described measurement of the velocity field of side contracted flow by UVP Monitor, follow up by assessment of boundary of the upstream wake, which is situated in the approach channel in front of the weir.

Comparison of proposed measures in Brantice–Kostelec section of river Opava
Korálová, Nikola ; Švancara, Jiří (referee) ; Zachoval, Zbyněk (advisor)
Diploma thesis deals with comparison of flow influenced by proposed measures with current status in Brantice-Kostelec section of the river Opava. The results of two-dimensional numerical model of steady uniform flow were used to assess the flow. The models were created using SMS – FESWMS for both of conditions. Thesis contains description of current status, design status, the theory of numerical modelling, comparison of the flow and evaluation of results.
