99. The sizing of a flow control device of the thin-walled weir type submerged downstream must be established using equation 4-4:

Equation 4-4:

where:

	Qs	=	Flow discharged by a submerged thin-walled weir (m3/s);
	Qns	=	Flow discharged by the non-submerged weir (m3/s);
	H1	=	Height of the runoff curve above the crest upstream of the weir (m);
	H2	=	Height of the runoff curve above the crest downstream of the weir (m).

O.C. 871-2020, s. 99.
