ABSTRACT:
A portable weir for measuring water flow through an irrigation canal is provided in an obliquely disposed check gate shaped to fit the cross sectional configuration of the canal. The weir opening in the check gate is reinforced by a cooperating network of reinforcing members to assure reliable readings from the weir even though it is subjected to rough handling in the field.
