Capacity of a broad-crested chute spillway with a curved outline in plan

Abstract

The capacity of a structure operating as a broad-crested spillway can be significantly increased, if the entrance and, especially, the outlet widths are increased, which for the same spillway length c and contraction width Bkey leads to a reduction of the ratio Bkey=Bkey/B and at the same time to an increase in the flow capacity of the structure.
