Description

Technical field [0001] The invention relates to the technical field of measurement, in particular to a hydraulic model test water surface line and flow velocity measuring device and method. Background technique [0002] In the design of hydraulic structures, in order to judge and analyze the flow capacity of the designed overflow weirs, gates, and spillways, a model with a corresponding scale will be used for testing, and then based on hydraulic formulas and laws. , The test results are processed and analyzed, and the over-current capacity parameters of the actual design conditions are obtained. Therefore, it is of great significance to accurately and quickly measure the flow capacity parameters of the model test. It should be noted that the measured flow capacity parameters are usually the elevation and flow velocity of the water surface line of the section. [0003] The existing method of measuring the water surface line of the hydraulic model test is: select the reference poin...
