CURRENT, TIDAL
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.
CURRENT-REFRACTION
Process by which wave velocity, height, and direction are affected by a current
CUSP
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.)
