Design of the multipurpose small water reservoir
Galuška, Martin ; Hyánková, Eva (referee) ; Doležal, Petr (advisor)
Thesis develops a simplified design of water management and construction solution in the area of Bezmerov. In the theoretical part basic functional objects are briefly described. Work itself is based on evaluation of landscape morphology from delivered countour lines and geological analysis and following design solution for dry retention water reservoir. For drawing part will be used programs PowerCivil – in which will be created direction solution for body of the dam, flooded area and their cross-sections and horizontal cuts. These will be further processed in program AutoCAD. Retention effects will be reviewed with program HEC-HMS. Design of objects for the water reservoir will be followed with hydrotechnical calculations, drawings and descriptions.
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.
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 Modelling of Flow over Spillway of the Letovice Dam
Křivohlávek, Roman ; Holomek, Petr (referee) ; Jandora, Jan (advisor)
This diploma thesis deals with numerical modeling of water flow. The numerical model was created to simulate the flow of water through the spillway of the Letovice dam. The spillway is constructed as a side channel and is located on the right bank. Autocad 2015 was used to create a 3D model, and FLOW-3D version 11.0.4 was used to create a numerical model.
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.
Determination of the capacity charakteristics of two-level fixed spillway
Chvátal, Petr ; Haluza,, Miloslav (referee) ; Šulc, Jan (advisor)
The Bachelor's thesis is conceived as a summary of existing information about two or more level fixed spillways of hydraulic structures and evaluates the capacity characteristics of individual variants. Its aim is primarily the formation and processing of these characteristics in the form of usable results, not only for design and research purposes, but also for numerical modelling.
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.
Numerical Modelling of Flow over Spillway in Small Dams
Vaněk, Jakub ; Roth, Tomáš (referee) ; Jandora, Jan (advisor)
The master´s thesis deals with the numerical modeling of flow in the emergency spillways of small dams. It is solved the flow rate capacity of a weir and of spillway called „duckbill-type“. Sharp crested weirs and long crested weirs are modeled using numerical simulations in ANSYS. Hydraulically complex spillway called „duckbill-type“ was modeled in the Flow-3D. The results of the discharge coefficients are compared with data in the hydraulic literature.
