The United States Army Corps of Engineers is a federal agency with a mission to provide vital public engineering services in peace and war to strengthen the nation's security, energize the economy, and reduce risks from disasters. It is also a major U.S. Army organization employing some 38,000 ...
The movement of water through small cracks, pores, interstices, out of a body of surface of subsurface water. The loss of water by infiltration from a canal, reservoir or other body of water or from a field. It is generally expressed as flow volume per unit of time.
Industry:Engineering
A rise above normal water level on the open coast due to the action of wind stress on the water surface. Storm surge resulting from a hurricane also includes that rise in level due to atmospheric pressure reduction as well as that due to wind stress.
Industry:Engineering
(1) That branch of physical geography which deals with the form of the Earth, the general configuration of its surface, the distribution of the land, water, etc. (2) The investigation of the history of geologic changes through the interpretation of topographic forms.
Industry:Engineering
Floating or (occasionally) truck-based plant which lifts the material through a suction pipe. It requires dilution water for material pickup, lift, and transportation. Often used to renourish beaches when material is pumped onto the shore from an offshore sand source.
Industry:Engineering
A interval at high or low water when there is no sensible change in the height of the tide. The water level is stationary at high and low water for only an instant, but the change in level near these times is so slow that it is not usually perceptible.
Industry:Engineering
(1) A ridge or embankment of sand and silt, built up by a stream on its flood plain along both banks of its channel.
(2) A large dike or artificial embankment, often having an access road along the top, which is designed as part of a system to protect land from floods.
Industry:Engineering
Sediment particles, often largely composed of quartz, with a diameter of between 0.062 mm and 2 mm, generally classified as fine, medium, coarse or very coarse. Beach sand may sometimes be composed of organic sediments such as calcareous reef debris or shell fragments.
Industry:Engineering
The zone of wave action extending from the water line (which varies with tide, surge, set-up, etc.) out to the most seaward point of the zone (breaker zone) at which waves approaching the coastline commence breaking, typically in water depths of between 5 to 10 meters.
Industry:Engineering
The nontidal vertical water movement in a harbor or bay. Usually the vertical motions are low; but when oscillations are excited by a tsunami or storm surge, they may be quite large. Variable winds, air oscillations, or surf beat also may cause oscillations.
