Field Investigation on Sediment Transport into the Submarine Canyon in the Fuji Coast with the new Type Tracers

摘要

The Fuji coast in Japan in one of the beach which is suffering from coastal erosion. One reason for erosin is seemed to be the offshore sediment transport through the submarine canyon in front of eroded area. The present paper concenrs the field investigation in order to confirm the sediment transport into the submearine canyon with two new type tracers. One tracer is the artificial sand and gravel made of the hard plastic. The other is the tracer with an ultrasonic transmitter. These tracers are very effective for tracking the sediment.
