Publisher's Synopsis
Excerpt from A Feasibility Study of a Wave-Powered Device for Moving Sand
The possibility existed that such a device could be useful in The general program of proposed beach improvement around The shores of The united states and other areas, particuiariy if offshore sand deposits, presentiy being sought, proved To be of sufficient size and quality To warrant Their being used as borrow areas for beach replenishment. If practicable, nearshore sources could provide sand for beach nourishment or possibilities might exist that an ocean-going dredge could unload within The reach of The wave - powered sand - moving device which would Then Transfer The sand To The surf zone. Although The use of devices such as modified amphibious military craft have been proposed for This purpose, The develop ment of an economically operated and soundly engineered machine has remained elusively beyond The reach of existing Technology. An additionai benefit To be derived from The use of a wave - powered sand-moving device is that it would use naturaiiy available energy To move considerable sand quantities To shore, except for The winching and emplacement phases of operation.
