Hydraulic Design of Spillways

Approved for public release; distribution is unlimited. 1. Purpose. This manual provides guidance for the hydraulic design of spillways for flood control or multipurpose dams. This manual applies to all Headquarter US Army Corps of) elements and all field operating activities (FDA) having responsibility for the design of Civil Work projects. 3. General. Procedures recommended herein are considered appropriate for design of features which are usable under most field conditions encountered in Corps of Engineers projects. Basic theory is present& as required to clarify presentation and where the state of the art, as found in standard textbooks, is limited. In the design guidance, wherepossible, both laboratory and prototype experimental test results have been correlated with current theory.
