Dam safety
hollow gravity dam
Energy; Hydro dam
A dam constructed of concrete and/or masonry on the outside but having a hollow interior and relying on its weight for stability.
broad-crested weir
Energy; Hydro dam
An overflow structure on which the nappe is supported for an appreciable length in the direction of flow.
rock anchor
Energy; Hydro dam
A steel rod or cable placed in a hole drilled in rock, held in position by grout, mechanical means, or both. In principle, the same as a rock bolt, but usually the rock anchor is more than 4 meters ...
attenuation
Energy; Hydro dam
A decrease in amplitude of the seismic waves with distance due to geometric spreading, energy absorption, and scattering, or decrease in the amplitude of a flood wave due to channel geometry and ...
inflow design (IDF)
Energy; Hydro dam
The flood flow above which the incremental increase in downstream water surface elevation due to failure of a dam or other water impounding structure is no longer considered to present an ...
flip bucket
Energy; Hydro dam
An energy dissipater located at the downstream end of a spillway and shaped so that water flowing at a high velocity is deflected upwards in a trajectory away from the foundation of the spillway.
