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 کاملScale Effects in Moderate Slope Stepped Spillways Experimental Studies in Air-Water Flows
Air-water flow measurements were conducted in two large-size stepped chute facilities (θ = 3.4 & 16o) to study experimental distortion caused by scale effects and result extrapolation to prototypes. The stepped geometries corresponded to moderate slopes typical of embankment dams and storm waterways. Experimental data included distributions of air concentration, air-water flow velocity, bubble ...
متن کاملSimple Design Criterion for Residual Energy on Embankment Dam Stepped Spillways
The stepped spillway design is associated with significant flow resistance and associated energy dissipation on the steps, yielding smaller, more economical downstream dissipation structures. A number of design guidelines were developed for steep stepped spillways typical of concrete gravity dams. The focus of this study is on embankment stepped spillways. A large set of air-water flow data is ...
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...
