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 conside...
متن کاملThe Study of Energy Loss in Stepped- Labyrinth Spillways
A ‘spillway’ is a structure used to provide the controlled release of flood water from upstream into downstream area of a dam. As an important component of every dam, a spillway should be constructed strongly, reliably and efficiently to be used at any moment. Labyrinth and stepped spillways are presented as appropriate modifications to those spillways hardly capable of managing the maximum pot...
متن کاملA Transition Flow Regime on Stepped Spillways the Facts
The stepped channel design have been used since more than 3,000 years. It is understood that low flows behave as successions of free-jets (i.e. nappe flow) while large discharges skim over the pseudo-bottom formed by the step edges. For a range of intermediate flow rates, a transition flow regime takes place. The dominant feature is stagnation on the horizontal step face associated with signifi...
متن کاملEnergy Dissipation and Residual Energy on Embankment Dam Stepped Spillways
Stepped spillways are designed to increase the rate of energy dissipation on the chute and to reduce the size of the downstream energy dissipator. It is essential to predict accurately the turbulent dissipation above the steps for large discharges per unit width corresponding to the skimming flow regime. New measurements were conducted in a large facility with a channel slope of 21.8o and a ste...
