Numerical Modelling of Weir Overflow
Šilhánková, Lenka ; Roth, Tomáš (referee) ; Jandora, Jan (advisor)
This thesis deals with the numerical modeling of water overflow over the front spillway. The aim of the thesis is to calculate various types of turbulent models and to assess the overflow coefficient on a sharp front spillway. The model was created in free software SketchUp, but the modeling itself was carried out in FLOW-3D software. The content of the work is a description of used software, design and calculation.

Reconstruction of the Hradisko Small Water Reservoir in the Radslavice Cadastral Area
Mrázová, Iva ; Kostelecký, Jiří (referee) ; Paseka, Stanislav (advisor)
This diploma thesis, called „Reconstruction of the small water reservoir Hradisko in the cadastral area of Radslavice“, focuses on the complex process of a reconstruction of the small water reservoir Hradisko. This work follows up on the bachelor’s thesis, in which the current state of the Hradisko reservoir was described in detail. Based on the survey of the dam and the flood using a GPS device, detailed project documentation was prepared. Within the solution for the reconstruction of Hradisko reservoir, a repair of the dam and the increase of the crown of the dam is proposed, new functional objects are dimensioned, the bottom is cleared of mud, including modifications in the flood, and other necessary steps for proper functioning of the crumbling no longer compliant reservoir are described. Functional objects are processed for two variants of the solution. The first option consists of the design of a bottom outlet and a safety spillway, and the second alternative involves the design of a combined functional block. In the end, the total costs of both options are quantified and compared on the basis of an indicative item budget.

Reconstruction of the Pod kravínem Dam
Lehotská, Lívia ; Dvořák, Bořek (referee) ; Jandora, Jan (advisor)
This diploma thesis deals with the reconstruction of small reservoir in collaboration with the company VZD Invest s. r. o. The first part aims at the basic description of the thesis subject – the small reservoir. Characteristics of small reservoir and calculations are processed in the second part. The third part is focused on the description of the current conditions. The main part consist of characteristics calculations of the small reservoir and proposal of the necessary reconstruction for future technical function. In conclusion, safety assessment of the proposed measures are evaluated.

Aspects affecting the price of the pond
Smolík, Jindřich ; Weigel, Lubomír (referee) ; Bradáč, Albert (advisor)
This thesis deals with the measurement of ponds and influencing aspects that may play a role in the valuation of ponds. In the first part of the thesis, the author discusses the basic concepts and issues that are necessary for the valuation of the pond. In the second part of the thesis is stated as a specific example of a pond situated on three pozemcíchy using the cost method of valuation in accordance with Decree successive steps and for comparing valuation program ABN14.

Numerical modeling of flow in spilway
Svoboda, Jiří ; Holomek, Petr (referee) ; Jandora, Jan (advisor)
The goal of the diploma thesis is the numerical modelling of flow in planned spillway of the Boskovice dam. In the introduction of this diploma thesis are described and divided basic spillways according to their types and profiles. There are also mentioned emergency spillways. Then the thesis introduces the description of calculation of overflow quantity, the description of mathematic modelling and used turbulent models. The next part is concerned with the technical description of the Boskovice dam, the creation of virtual 3D model of spillway and spillway chute in the AutoCAD 2020 software and concerned with the control and revision of model in the Blender software. In the end of the thesis are mentioned results of numeric modelling of flow gained from the Flow-3D software and the comparison of results with the research of hydraulic model implemented at Water structures institute of Faculty of Civil Engineering of BUT.

The design of the multipurpose small water reservoir
Pitka, Roman ; Dobešová, Renata (referee) ; Doležal, Petr (advisor)
Master´s thesis aims to design multipurpose reservoirs in the river basin Žlebovský potok in cadastre Vysoké Popovice. The main purpose of the reservoir will be improving the drainage conditions in the basin of the river and revitalization. The reservoir will be designed according ČSN 75 2410 – Malé vodní nádrže. The master´s thesis consists of a text section, hydraulic calculations and graphic attachments.

Modelling of Flow over Spillway of the Slušovice Dam
Menšík, Kryštof ; Holomek, Petr (referee) ; Jandora, Jan (advisor)
The master thesis is focused on the mathematical modelling of water flow through a safety object. It explains the principle of mathematical modelling and its laws. It presents the mathematical models used in numerical modelling. The process of mathematical modelling of the Slušovice side channel spillway is then described. The results of the modelling are then presented and evaluated.
