Simple 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 کاملEmbankment dam spillways and energy dissipators
For the last fifty years, the design floods of a number of embankment dams were re-evaluated and the revised spillway outflows are often larger than the original design discharges. Several embankment overtopping protection systems were developed for earthfill structures, and the applications range from river dykes to tsunami protections including embankment dams. Well-known designs include timb...
متن کاملForecasting embankment dam behaviour with artificial intelligence
Forecasting dam behaviour is of paramount importance to avoid collapses. It consists of detecting and controlling deterioration mechanisms. This paper sets out to propose a multi model methodology to model complex dynamic systems, such as dams. It defines three models based on expert knowledge: a structural model, a functional model and a behavioural model. They are developed from the stories o...
متن کاملSeismic Behavior of Zoned Core Embankment Dam
The aim of this investigation is to study the dynamic behavior of a zoned core earth-fill dam. Due to lack of suitable clay materials, the Mamloo dam is designed as zoned core that is composed of three vertical zones including central lean clay (CL) core and two sides clayey gravel (GC) layers. Seismic behavior of dam was analyzed in two cases including homogenous clayey core and zoned core by ...
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...
