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 ...
A type of wave in shallow water (i.e., where the depth of water is less than 1/8 to 1/10 the wavelength). The surface profile is expressed in terms of the Jacobian elliptic function cn u; hence the term cnoidal.
Industry:Engineering
Rate of transport of sedimentary material parallel or perpendicular to the shore in the littoral zone. Usually expressed in cubic meters (cubic yards) per year. Commonly synonymous with longshore transport rate.
Industry:Engineering
Lands whose saturation with water is the dominant factor determining the nature of soil development and the types of plant and animal communities that live in the soil and on its surface (e.g. Mangrove forests).
Industry:Engineering
That part of a standing wave where the vertical motion is least and the horizontal velocities are greatest. Nodes are associated with clapotis and with seiche action resulting from wave reflections. Compare loop.
Industry:Engineering
The intersection of the ground surface with a vertical plane; typically perpendicular to the local shoreline, and may extend from the behind the dune line or the top of a bluff to well seaward of the breaker zone.
Industry:Engineering
An ocean wave parallel to a coast, with crests normal to the shoreline. An edge wave may be standing or progressive. Its height diminishes rapidly seaward and is negligible at a distance of one wavelength offshore.
Industry:Engineering
A detached portion of a barrier beach between two inlets. It commonly has dunes, vegetated areas, and swampy terranes (see barrier flat) extending from the beach into the lagoon. Example: Outer Banks, North Carolina.
Industry:Engineering
A current that runs continuously, independent of the tides and temporary causes. Permanent currents include the freshwater discharge of a river and the currents that form the general circulatory systems of the oceans.
Industry:Engineering
Beach topography consisting of sand bars that have welded to the shore during the recovery stage after a storm. At low tide, water ponds in the runnels and flows seaward through gaps in the ridge.
Industry:Engineering
The solid rock that underlies gravel, soil, and other superficial material. Bedrock may be exposed at the surface (an outcrop) or it may br buried under a few centimeters to thousands of meters of unconsolidated material.
