Proposal of small earth dam
Stoklas, Jan ; Duchan, David (referee) ; Špano, Miroslav (advisor)
The subjekt of this bachelor thesis is the study of a small water reservoir in a particular locality. It consists of a text part and a drawing part. The text part contains brief summary of the issues of small water reservoirs, description of the locality, determination of design flow, needed hydrotecchnical calculations and design of expected technical solution. The drawings show the design of the dam, the combinated funtional object and the modified flooded area.

Design of the multipurpose small water reservoir
Rumanová, Jana ; Hyánková, Eva (referee) ; Doležal, Petr (advisor)
Master's thesis aims to design a small water reservoir. It is the dry water reservoir which is situated above a built-up area. The main function of this reservoir is a flood protection. Digital terrain model is created in a program BENTLEY MicroStation V8i – Power Civil. Focusing points in a data file are used in a process of creating of the DTM. Adjustments are done in AutoCAD. Particular hydro-technical calculations are calculated in a program Microsoft Excel. A program HEC-HMS is used for an assessment of a flood wave transformation and a program HEC-RAS is used for a water runoff simulation via emergency spillway.

Numerical modelling of flow over auxiliary spillways
Kostelecký, Jiří ; Golík,, Pavel (referee) ; Zachoval, Zbyněk (advisor)
The thesis deals with possibilities of numerical modelling of an overflow over selected types of auxiliary spillways and then the possibilities are verified in particular localities. In thesis, there is carried out the determination of capacity of selected spillways by using several methods: the calculation of the overflow equation, one-dimensional and two-dimensional numerical models and physical model. The author created parametric analysis to each single method. Parametric analysis represent various hydraulic conditions. Subsequently, there is possible to express the effect of parametric analysis. The author makes a comparison of water levels received by mentioned methods set out under the specific hydraulic conditions by calibration of each model with the physical model. Finally, author recommends values of all coefficients which have an impact on results of numerical modelling of the flow over selected types of weirs mostly using like auxiliary spillways.

Study of Possibility to Build Small Dams near Vyškov
Richter, Štěpán ; Žatecký, Stanislav (referee) ; Jandora, Jan (advisor)
This thesis deals with the design of small reservoirs at Vyškov na Moravě. Projected reservoirs’ dams are earth-fill and homogenous and each one is equipped with the bottom water outlet and the emergency spillway. The first reservoir, located on the tributary of the Drnůvka river, has the fountain type emergency spillway and the feed pipe bottom water outlet. The reservoir of the Merchanice river, situated at the Vyškov airport, is equipped with the lateral emergency spillway and the feed pipe bottom water outlet. The third design is the reconstruction of the Marchanka reservoir projecting the dam raise. For this small reservoir two variants of functional installations were elaborated.
