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...

The Monforte de Moyuela dam, also known as Ermita la Virgen del Pilar is a Roman reservoir built on tributary of the Aguasvivas River (Ebro basin, Spain). A multidisciplinary study has been carried out to investigate this kind water infrastructure. It fifth-highest dam (16.8 m) in Iberian Peninsula and seventh Empire. initial was ca. 100 B.C.–10 A.D., probably period Augustus, like other nearby...

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 ...

Flood waves resulting from dam breaks and flash floods have been responsible for numerous losses. In the present study, sudden flood releases were investigated down a large stepped waterway initially dry. A new experimental technique was developed to obtain instantaneous void fractions, bubble count rates and velocities. Unsteady air-water flow properties were recorded with arrays of conductivi...
