Description :
This study aims to investigate the bed features in the tide-dominated Changjiang (Yangtze) Estuary using a side-scan sonar and a depth recorder, and to examine the bed material transport pathways on the basis of the maximized gross bedform-normal transport. The bed material migrations in terms of relative maximum gross transport show a satisfactory agreement with the sonar mapping in the dry season. The relative maximum gross transport as an independent estimator of migration direction, can be used to effectively determine the bed material transport directions in the Changjiang Estuary.
