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 ...
