Monitoring Sediment Supply

Washington Sea Grant

Dam removal on the Elwha delta has led to a massive flux of sediment to the coastal zone, leading to what is in effect the largest beach nourishment experiment ever in Washington State. Washington Sea Grant, in collaboration with the US Geological Survey, the Lower Elwha Klallam Tribe and others, is investigating the fate of that sediment and particularly how it acts to re-nourish eroding beaches. The results can be applied to problems associated with beach erosion due to climate change and sea level rise.
