Renovation of a water reservoir in the village of Žďárná
Pastorková, Nikola ; Krčma, Marek (referee) ; Duchan, David (advisor)
The theme of this diploma thesis is to restore the existing small reservoir in the village Žďárná. A new safety spillway and bottom outlet will be built, the flood will be shaped according to the cross-sections and the dam of the water reservoir will be fortified. The designed objects will be hydraulically verified. Using the HEC-HMS program, a hydrological model of the river basin is created and subsequently a derived flood wave PV20.

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.

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.

Modelling of Flow over Spillway of a Dam
Desatová, Martina ; Holomek, Petr (referee) ; Jandora, Jan (advisor)
This thesis deals with mathematical modelling of water flow through the safety object. It explains the principle of mathematical modelling and its laws. There is also present-ed the mathematical models used by numerical modelling. The results of mathemati-cal model Koryčany are included in this thesis compared with hydraulic calculations and physical model.

Modelling of Flow over Spillway of the Letovice Dam
Škrach, Mikuláš ; Holomek, Petr (referee) ; Jandora, Jan (advisor)
The thesis is concerned on numerical modeling of a scheduled spillway on water structure Letovice. The goal of the thesis is to verify hydraulic calculation using numerical modeling and to verify the capacity of the spillway. The spacial model was created in SketchUp program and the numerical modeling was implemented in Flow-3D program. The reason to recalculate the spillway is its reconstruction and extension in order to make high a capacity of it in the final project of Letovice water structure whole reconstruction.

Safety Assesment of the Těšany Dam during Floods
Desatová, Martina ; Holomek, Petr (referee) ; Jandora, Jan (advisor)
The aim of this bachelor thesis is safety assessment of the Těšany dam in the conversion of control floods. The content of the work is a description and summary of basic data on the water structure the documents and the resulting values, including descriptions of hydraulic calculations. The requirements ČSN 75 2935 were a basis for this thesis. The result of thesis is evaluation of current condition of dam and associated facility.

Renovation and reconstruction of small water reservoir
Pavlík, Tomáš ; Doležal, Petr (referee) ; Hyánková, Eva (advisor)
This diploma thesis deals with analysis of small water reservoirs and their water management. The work is divided into two parts. The first part contains research and the second one is dedicated to the project of small water reservoir. The research describes the basic division of small water reservoir and their construction and technical equipage. The knowledge that has been found is applied in the project. The project describes the renovation of small water reservoir Kančí obora and pool, in k.ú Nové Bránice and Moravský Krumlov.

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.

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.
