Outline
In order to solve the real-time online flow monitoring under complex conditions of wide and shallow river sections, based on the applicability of conventional online flow measuring equipment, the combined application of two-way probe H-ADCP facing each other was proposed. Taking the Gaogang Water Conservancy Project at the source of water intake of the East Route of the South-to-North Water Transfer Project as an example, the whole process of numerical simulation of river sections, flow field analysis, equipment installation, comparison measurement setting and other aspects were carried out applied research. The results show that the change of flow field in the flow measuring reach is complicated under different operation conditions of the control hub gate pump. The dual probe H-ADCP can be installed at the same section and the same height, and the ultrasonic beam crossing will not affect the collection of effective unit velocity data. The relationship between the double index velocity and the average velocity of the section can be established to calculate the real-time flow, and the accuracy of the combined applied flow measurement is higher than that of the single H-ADCP flow measurement data. The research results form a set of real-time flow monitoring application methods under complex conditions of wide and shallow rivers, which can provide ideas for the combined use of online flow measuring equipment.
