Channel Flow Studies Using Driftwood Density Analysis In Elger Bay, Camano Island, Wa, Rebeca Becerra, Jasmine Bates, Clairissa De La Vergne
Symposium Of University Research and Creative Expression (SOURCE)
Previous studies on Elger Bay, Camano Island, WA hypothesized that the bay has been emptying of stored driftwood since the 1970's. To test this hypothesis, we conducted a research project using a combination of field data and historical imagery analysis with Google Earth and ArcGIS to mathematically compare the density of driftwood. Changes in driftwood area may indicate changes in sea level rise, bay subsidence, and/or anthropogenic activity. We found that the maximum driftwood extent was actually closer to the 1950's than the 1970's. In addition to overall extent we investigated the overall channel flow along Elger Bay by analyzing …
