flood gate
Engineering; Coastal engineering
A gravity outlet fitted with vertically-hinged doors, opening if the inner water level is higher than the outer water level, so that drainage takes place during low water.
seismic reflection
Engineering; Coastal engineering
The return of part of the energy of seismic waves to the earth’s surface after the waves bounce off an acoustic boundary (typically rock or material of different density).
specific gravity
Engineering; Coastal engineering
The ratio of the weight of unit volume of any material to the weight of unit volume of water at 4 deg C, Gs = γs/γw. Typical values of Gs for soil solids are 2.65 to 2.72.
ice age
Engineering; Coastal engineering
A loosely-used synonym of glacial epoch, or time of extensive glacial activity; specifically of the latest period of widespread continental glaciers, the pleistocene Epoch.
plunge point
Engineering; Coastal engineering
(1) For a plunging wave, the point at which the wave curls over and falls. (2) The final breaking point of the waves just before they rush up on the beach.
sand spit
Engineering; Coastal engineering
A narrow sand embankment, created by an excess of deposition at its seaward terminus, with its distal end (the end away from the point of origin) terminating in open water.
beach berm
Engineering; Coastal engineering
A nearly horizontal part of the beach or backshore formed by the deposit of material by wave action. Some beaches have no berms, others have one or several.
