Any of the parts of the nearshore current system that flow parallel to shore before converging and forming the neck
of the RIP CURRENT.
The tidal current toward shore or up a tidal stream. Usually associated with the increase in the height of the tide.
See INSHORE CURRENT.
Any current in the littoral zone caused primarily by wave action; e.g., LONGSHORE CURRENT, RIP CURRENT.
See also CURRENT, NEARSHORE.
The littoral current in the breaker zone moving essentially parallel to the shore, usually generated by waves
breaking at an angle to the shoreline.
An instrument for measuring the velocity of a current
A current in the NEARSHORE ZONE. (See Figure A-1)
See OFFSHORE CURRENT.
See CURRENT, TIDAL.
See PERMANENT CURRENT.
See RIP CURRENT.
A narrow, deep, and swift ocean current, as the Gulf Stream. CURRENT, DRIFT.
CURRENT SYSTEM, NEARSHORE
See NEARSHORE CURRENT SYSTEM.
The alternating horizontal movement of water associated with the rise and fall of the tide caused by the
astronomical tide-producing forces. Also CURRENT, PERIODIC. See also CURRENT, FLOOD and CURRENT, EBB.
Process by which wave velocity, height, and direction are affected by a current
One of a series of short ridges on the FORESHORE separated by crescent-shaped troughs spaced at more or less
regular intervals. Between these cusps are hollows. The cusps are spaced at somewhat uniform distances along beaches.
They represent a combination of constructive and destructive processes. Also BEACH CUSP. (See Figure III-2-23.)
