For width to be smaller or the less channel of flow-rate ratio, when channel width is more than 1 meter, measuring structure cost can increase very much,
And do not do at this time measuring structure directly use channel stage-discharge empirical relation curve flow measurement when precision can be very low.Water level method
Metering method is single, ga ge relation formula can only be used to calculate that water flow is not actual measurement water flow velocity, measuring and calculating accuracy is low, efficiency
It is low.
