Determination of Q / H characteristic of atypical measuring flume
Boháč, Daniel ; Zubík, Pavel (referee) ; Žoužela, Michal (advisor)
This bachelor’s thesis deals with streamflow measurement with focus on measuring systems using the Q/H characteristic. The thesis includes the description of the commonly used measuring weirs and flumes. The main task of this thesis is a specific project of atypical measuring flume. This flume will become a part of a rigid weir and will measure the minimum residual flow rates. In the Laboratory of Water Management Research of the Institute of Water Structures of the Faculty of Civil Engineering of the Brno University of Technology, the author has done extensive model research. In this research, various variants of the shapes and dimensions of the atypical measuring flume were analysed. The thesis also includes data processing of the said research and evaluation. The result of this work is the choice of the optimal variant of shapes and dimensions of atypical measuring flume and to determine its Q/H characteristic.

Determination of the Q/h characteristic of storm water overflow chamber
Škrancová, Markéta ; Ježek, Jiří (referee) ; Žoužela, Michal (advisor)
The main task of this bachelor thesis is to determination the Q / h characteristics of the sluice chamber in the wastewater treatment plant on a physical hydraulic model, processing of all measured values and their analysis. All measurements were performed by the author of this work in the premises of the Laboratory of Water Management Research of the Institute of Water Structures of the Faculty of Civil Engineering of the Brno University of Technology. The result of the bachelor thesis is an equation used to determine the immediate flow which will be entered into to evaluation unit of the newly built measuring system. It will be located in the sluice chamber of the wastewater treatment plant and will be used to measure the flow and flowed amount of overflow water into the Svratka River.

Interactive Instructional Models of Water Management Structures for Hydro-technical Laboratory of the High School of Civil Engineering in Vysoké Mýto
Požárová, Miroslava ; Kříž,, Lubomír (referee) ; Žoužela, Michal (advisor)
In 2014 a new Hydro-technical laboratory was built at the High School of Civil Engineering in Vysoké Mýto. The laboratory’s hydraulic circuit is equipped with a reserve line enabling independent standing models of hydro-technical structures to be connected. Two interactive instructional models are designed for this laboratory. The first is a model of a concrete dam. The dam is equipped with one bottom outlet, a hydraulic power plant and an emergency spillway crest gate. The discharge part of the model is equipped with a downflow baffle for regulating the tailwater level and a measuring weir enabling the flow rate to be measured at the discharge point from the model. The total capacity of the model is 10 l/s. The second model is a model of a weir structure. The weir structure consists of a controlled segment sluice gate weir composed of three sections. The model includes a one-nave lock chamber and hydraulic power plant. The tailwater level can also be regulated using a downflow baffle. The total capacity of this model is 20 l/s. The models can be used for teaching the subjects of hydraulics, hydrology and hydro-technical structures. They can be used to demonstrate various hydraulic phenomena and to describe individual functional objects using specialist terminology. This thesis contains the full project documentation for both proposed models, including hydro-technical calculations and text appendices.

Volume measurement discharge in surface runoff for refine continuous measurement
ŠEBOR, Ondřej
The thesis is divided into theoretical and practical part. The theoretical part includes issues associated with runoff and discharge, methods for discharge measurement and measurements of uncertainties. The practical part of the thesis describes a specific process flow measurement in Kopaninský and Jenínský stream. There is a familiarization with the water flow velocity measurement and comparison methods of volume measurement discharge with continuous measurement. The results of the practical part served to refine the rainfall-runoff processes in research catchment areas. Refined values of the flow rate were used as input data for the calculation of the runoff coefficient and for quantifying the losses of nutrients from the catchment areas. Calculation of the runoff coefficient and nutrient losses were compared for the original and the revised equation discharge curve. Volume measurement discharge has shown that the different conditions above measurement weir during continuous monitoring lead to the uncertainties of measurement. That´s why one has to approach to each flowmeasurement individually and consider the situation in a particular installation.

Methods for discharge measurement in surface runoff - measurement of uncertainties.
ŠEBOR, Ondřej
The thesis is divided into theoretical and practical part. The theoretical part includes issues associated with runoff and discharge, methods for discharge measurement and measurements of uncertainties. In the practical part of the thesis a specific process flow measurement in Kopaninský stream is describes. The water flow velocity measurement is described and comparison of methods volume measurement discharge with continuous measurement is carried out. The purpose of this work is to gain more accurate data inputs for modeling of rainfall-runoff processes, especially in the calibration and validation stage, as well as for hydrological analysis and other studies conducted in research projects. Often due to different conditions upstream the weirs incorrect results may occur during measurements, so it is important to ensure verification of universal equations in the field with other methods of discharge measurement for further appropriate application. The result of this work is literature overview concerning runoff measurements techniques and measurements uncertainties serving as a basis for the continuation of the thesis. Further the results of practical part are used for primary verifications of continuous discharge monitoring and determination of a new equation of consumption curve.
