The author presents here a generalized discharge formula which can be applied to all kinds of the rectangular weirs. This formula has no restriction as to the width b and the value b/B, h/(h+D), and m=h/b (B : channel width, D : depth of weir, h : head). Consequently to weirs with any geometrical shape, i.e., for all weirs of b/B=0〜1,h/(h+D)=0〜1,m=h/b=0〜∞, and further to weirs having any dimension, this formula can give the coefficients of discharge respectively. Estimated discharge coefficients as well as experimental data of weirs for b=0.10,0.05,0.025m and for various values of B and D result in this genera1ized discharge formula. Excepting special cases of free overfall, small suppressed weir and full depth weir for b/B≒1,this formula gives discharge coefficients within ±1% error.
