GLOSSARY OF TERMS 



ACCRETION. May be either NATURAL or ARTIFICIAL. Natural accretion is the 

 buildup of land, solely by the action of the forces of nature, on a BEACH 

 by deposition of water- or airborne material. Artificial accretion is a 

 similar buildup of land by reason of an act of man, such as the accretion 

 formed by a groin, breakwater, or beach fill deposited by mechanical 

 means. Also AGGRADATION. 



ADVANCE (of a beach). (1) A continuing seaward movement of the shoreline. 

 (2) A net seaward movement of the shoreline over a specified time. Also 

 PROGRESSION. 



AGE, WAVE. The ratio of wave velocity to wind velocity (in wave forecasting 

 theory) . 



AGGRADATION. See ACCRETION. 



ALLUVIUM. Soil (sand, mud, or similar detrital material) deposited by 

 streams, or the deposits formed. 



ALONGSHORE. Parallel to and near the shoreline; LONGSHORE.
