8 Most Common Types of Spillways (With Diagram)

The effect of the corbel is to shift the nappe (and, hence, the spillway profile) backward which results in saving of concrete. If the height of the vertical face of the corbel is kept more than 0.3 times the head over the crest, the discharge coefficient of the spillway will be practically the same as if the vertical face of the corbel extended for the full height of the spillway. Type # 3 ...
