ABSTRACT - Ediz Hook has developed into a 5.6-km-long spit during the Holocene. The available sedimentparticles of clay, silt, sand, gravel, or cobble, transported by water, are called sediment. supply has been reduced in this century, from 260,000 m³/yr to 31,000 m³/yr by damming of the Elwha River and protecting the base of an eroding sea cliff, updrift (west) of the spit. Serious erosion necessitated some mitigating action, and in 1977-1978 a project combining rock revetment and beach nourishment was initiated at a cost of $5,600,000. Further rehabilitation, in 1985 at a cost of $970,000, has essentially stabilized the spit. Further beach nourishment will be provided as needed.
