River regulation with flood protection
Zvolánek, Radim ; Špano, Miroslav (referee) ; Duchan, David (advisor)
This work describes the assessment of the capacity of the river Chrudimka on the river kilometers 87,837 to 93,173. The hydraulic computation was done for flow with periodicity of 10, 50 and 100. The calculation in the HEC-RAS program is described. Based on the results, flood protection is proposed. Flood protection is verified by a control hydraulic calculation The results are outlined in the drawing documentation

DETERMINATION OF FLOW AND LOAD CHARACTERISTICS OF SURFACE FLAP GATES THROUGH PHYSICAL AND NUMERICAL MODELING
Picka, Daniel ; Možiešik,, Ľudovít (referee) ; Pochylý,, František (referee) ; Šulc, Jan (advisor)
The subject of research were effect of elevated water level in the downstream apron on the weir flow capacity and load characteristics of the flap gate. The thesis is focused on possibilities of physical and CFD modeling of flap gate weir flow. In the introduction are contained current condition of knowledge, perfomed model studies conducted in the Czech republic and abroad, as well as flap weirs realized in our country and in the world. This is followed by experimental physical research on family of weir structure models in scales 1:1 (prototype), 1:2 and 1:2.5. Options CFD simulations a flap gate weir are contained in chapter of CFD modeling. In conclusion are compared physical methods with CFD simulations on flap gate weir.

Assessment of the Possibilities The Revitalization of a Watercourse Osoblaha – reach II
Vysloužilová, Lucie ; Peterek, Lumír (referee) ; Uhmannová, Hana (advisor)
This thesis deals with examining the possibility of revitalizing the watercourse Osoblaha. It flows through the cadastral territories of municipalities Bohušov, Osoblaha and Kašnice u Bohušova. In this thesis there will be proposed a measure to increase biodiversity of the flow. The trough will be loosened in appropriate segments, oxbow lakes and ponds will be designed. Also the bank shelters for fish stock will be suggested. For slope stabilization will be used reinforcement of fresh willow fences. Impermeable shoots or disintegrating oxbow lakes will be projected in the straight sections of the flow.
