Abstract
Abstract: In human life, water resources are inseparable. In recent years, China's population growth has accelerated, and the industrial level has been continuously improved, resulting in the rapid use and waste of water resources. The protection and rational distribution of water resources is the most pressing issue in China's water resources. At present, the water measuring facilities of the U-shaped channel mainly include a straight wall measuring pool, a parabolic throat measuring pool and a long throat measuring pool. In view of the problems in irrigation measurement, the empirical water measurement of basic open channel and automatic flow measurement system in irrigation district is summarized to improve the accuracy, fairness and rationality of water measurement, and promote irrigation district management to a higher level.
