Water control structures or Gates

A typical design of open type pond inlet structure

Unless the head over the upper sill is less than the depth of the shutter opening value of Q can be obtained by using the expression Q = CdA(2gh)^½. The head is being measured to the centre of the opening. Sometimes pipes are used instead of rectangular vents in the pond inlet gate. The size for one ha pond inlet gate should not be less than 300mm of the pipe diameter.
