Novel water metering method for open channel based on multi-point water level

Abstract

The invention relates to a novel open channel water metering method based on multipoint water levels. The water flow is worked out according to a modern computer computing technique by utilizing the traditional open channel hydraulic theory. In the method, three water gauges arranged in a control channel section at regular intervals are utilized to measure the overflowing water level value, the traditional open channel hydraulic theory is utilized to respectively calculate the overflowing amount of each section in a control channel section, and then the overflowing amount flowing through the control channel section is obtained through weighted average.

Description

technical field

[0001] The invention belongs to the field of engineering technology, and in particular relates to a new method for measuring open channel flow based on the combination of traditional open channel hydraulic theory and modern computer computing technology. Background technique

[0002] Water-measuring equipment and water-measuring technology in irrigation areas are basic measures to realize planned water use and control the quality of irrigation water, and are necessary tools and means to implement fee-by-square and promote water conservation. The commonly used methods of water measurement in irrigation areas include: one is to use hydraulic structures to measure water, which is more economical and convenient; It is used when there is no hydraulic structure or the existing hydraulic structure cannot be used for water measurement, or when the required water measurement accuracy exceeds the accuracy that the hydraulic structure can achieve; the third is to use th...
