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.
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.
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.
Safety Assesment of the Horní Dunajovice Dam during Floods
Křivohlávek, Roman ; Jareš, Zbyněk (referee) ; Jandora, Jan (advisor)
The aim of this bachelor thesis is safety assesment of the Horní Dunajovice dam during control floods. The requirements ČSN 75 2935 were a basis for this thesis. The result of thesis is evaluation of current condition of body of dam and associated facility. Proposal of requested measures is attached.
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.
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.
Study of flood routing of extreme flood with emergency spillway of the Nové Mlýny dam
Slavětínský, Radek ; Rainer, Vít (referee) ; Jandora, Jan (advisor)
This diploma thesis deals with reliability assessment of the Nové Mlýny dam during flood routing of extreme flood with emergency spillway. Capacity of current emergency spillways was assessed and flood routing for theoretical flood waves was examined. Results showed insufficient capacity of the spillway for routing of 10 000 year flood. Therefore variants of corrective measures leading to reliability increase were proposed.
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.
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.
