Numerical Modelling of Flow over Spillway
Holinka, Matouš ; Hodák,, Jiří (referee) ; Jandora, Jan (advisor)
This thesis deals with the solution of numerical modeling. Consequently problems associated with the flow of the water over spillway of the specific water structure. In this case numerical modeling means modeling of fluid movement, which is described by mathematical means. Especially nowadays, when a lot of spillways need to be recalculated, whether it meets the capacity demands, or there is no need to tackle reconstruction. With today's software capabilities there is a wide range of commercial and freeware resources. The numerical model, compared to physical model is less accurate which is, on the otherhand, physical model is usually financially and time-consuming. The following work simulates the behavior of water on the edge of the spillway, in the trough and then behind the trough. The result is a comparison of the water depth in the trough calculated by the numerical and the physical model.

Safety Assesment of the Ostrov nad Oslavou Dam during Floods
Holinka, Matouš ; Holomek, Petr (referee) ; Jandora, Jan (advisor)
This Bachelor's thesis deals with the small water reservoir Ostrov nad Oslavou and its assessment with regard to the passage of the flood wave. Drawing takes place according to the requirements TNV 75 2935 (technical standard). In the first chapters we gradually describe the purpose of the water structure. In the following chapters we summarize the basic data, documents and values, including description of hydraulic calculations. Followed by analyzing of the maximum permissible safe water level and then setting of the maximum check flood water level in the reservoir as a result of transformation of the flood wave. In the final chapter there is a comparison of those two levels, their evaluation and recommendations. These measures are designed to ensure the safety and reliability of the water structure.
