Document Type: Journal Paper


Review of past studies and investigations, including prototype measurements and hydraulic model tests; reveal some indications of sediment transport and diffusion in the vicinity of the Columbia Estuary and Entrance. These indications reveal a unique pattern of sediment transport and diffusion prevailing in this region. This leads to the conclusion that the estuary is acting as a trap for collection of bottom sediments and that, immediately offshore, the forces of erosion and accretion have established a regime that is also worthy of detailed further study.
