CURRENT^ EDDY - A circular movement of water of comparatively limited 

 area formed on the side of a main current, Eddies may be created 

 at points where the main stream passes projecting obstructions. 



CURRENT, FSiEDER - The current which flows parallel to shore before 



converging and forming the neck of a rip current. See also RIP. 



CURRENT s FLOOD - The movement of the tidal current toward the shore or 

 up a tidal stresm= 



CURRENT, INSnCRE - Any current inside the breaker zone. 



CURRENT, LITTORAL - The nearshore currents primarily due to wave action^ 

 e»g. Longshore currents and Rip currents. See also CURRENT, >IEAR- 

 SHORE, ~~ 



CURRENT, LONGSHORE - The inshore current moving essentially parallel to 

 the shore „o usually generated by waves breaking at an angle to the 

 shore line. 



CURRENT SYSTE?'!, NEARSHORE - The cijrrent system caused primarily by wave 

 action in and near the breaker zone and which consists of four 

 par-ts: the shoreward mass transport of water; longshore currents; 

 seaward retui-n flow., including rip currente; and the longshore 

 movement of the expanding heads of rip currents, 



CURRENT, OFFSHCPJi; - (l) Any current in the offshore zonej (2) Any 

 c\irrent flowing away from shore, 



CURRENT, PERIODIC - A current^, caused by the tide-producing forces of 

 the mccn and the sun. which is a part of the same general move- 

 ment of the sea manifested in the vertical rise and fall of the 

 tides, Also CURRENT, TIDAL. 



CURRENT, PER^L4NENT - A current that runs continuously independent of 

 the tides and temporary causes. Permanent currents include the 

 fresh water dj_scharge of a river and the currents that form the 

 general circulatory systems of the oceans. 



CURRENT 5 RIP - A narrow current of water flowing seaward through the 

 breaker zone, A rip current consists of three parts; (l) The 

 "feeder currents" flowing parallel to the shore inside the 

 breakers: (2) The "neck" - where the feeder currents converge 

 and flow through the brealcers in a narrow band or "rip"; and 

 (3) The "head" - where the current widens and slackens outside 

 the breaker line., a:lsc RIP SURF. (See Figure A-?) 



CURRENT, STREAM - A narrow, deep, and fast-moving ocean currents
