Net Shore-Drift Along The Strait Of Juan De Fuca Coast Of Clallam County, Washington, Steven C. (Steven Craig) Bubnick

WWU Graduate School Collection

Net shore-drift along the north coast of Clallam County, Washington, was determined by using geomorphic and sedimentologic indicators. These indicators include changes in bluff morphology, delta plan form, beach width and slope, sediment size gradation, direction of stream mouth diversion, spit growth, deposition and erosion at drift obstructions, identifiable sediment, relict beach ridges, and imbricated beach sediment.

Irregularities in the coastline have caused the shore drift to become divided into drift cells, each displaying zones of supply, transportation, and accumulation. Drift direction determinations were made through field observations of the indicators, supplemented by the study of photographs, topographic maps, and …
