Line 22: *Ogee-crested weir An ogee-crested weir is a special type of weir, generally used as a spillway of a dam as shown in figure. The crest of an ogee weir slightly rises up from the inside edge (i.e., a slight hump on top of the weir) and after reaching the maximum rise of 0.115 H (where H is the height of the water above the inside edge) falls in a parabolic form over the edge of the weir.
