NEARSHORE CURRENT SYSTEM
The current system caused primarily by wave action in and near the breaker zone, and which consists of four parts:
the shoreward mass transport of water; longshore currents; seaward return flow, including rip currents; and the longshore
movement of the expanding heads of rip currents. See also NEARSHORE CIRCULATION.
(1) The narrow strip of land which connects a peninsula with the mainland, or connects two ridges. (2) The narrow
band (rip) of water flowing seaward through the surf. See also RIP CURRENT.
Roughly triangular promontory of land jutting into the sea, often consisting of mobile material, i.e. a beach form.
A set consisting of: (a) stations for which geometric relationships have been determined and which are so related
that removal of one station from the set will affect the relationships (distances, directions, coordinates, etc.) between the other
stations; and (b) lines connecting the stations to show this interdependence.
The cut made by waves in a shoreline of emergence.
An area in which the predominant direction of the LONGSHORE TRANSPORT changes.
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.
The process of replenishing a beach. It may occur naturally by longshore transport, or be brought about artificially
by the deposition of dredged materials or of materials trucked in from upland sites.
Refers to analysis of coastal processes using computational models.
