A Study on the Experiment of Labyrinth Weir

This paper is based on experiments,detailedly introduced the water flow experiment process of the trapezoidal labyrinth weir model,analysis and study the hydraulic characteristics,discharge capacity and discharge efficiency of the trapezoidal labyrinth weir,and the influence of ventilation facilities to discharge capacity and discharge efficiency,and use the graphic form to show the test results.This experiment conclusion and results has a good reference value to the labyrinth weir engineering design and application.And can offer a direct and powerful evidence and theoretical basis for some Specific application of the labyrinth weir.
