Dune erosion models and swash zone kinematics from remote video observations

Creator:

Palmsten, Margaret L.

Abstract:

The subaerial beach, composed of sand dunes and the foreshore, provides a natural buffer zone between vulnerable land and the dissipation of storm wave energy due to wave breaking. The natural beauty of this region is attractive to people, and as a result, significant investment has been placed in this...

Coastal sand dunes in the U.S. Pacific Northwest : regional variability in foredune geomorphology and associated physical vulnerability to hazards

Creator:

Mull, Jeremy M.

Abstract:

Coastal foredunes protect lives, infrastructure, and ecosystems during severe winter storms. In the U.S. Pacific Northwest (PNW), coastal foredune geomorphology is determined by both physical and ecological mechanisms. Before the 1900's, the native plant Elymus mollis was the dominant dune grass and dune morphology was largely determined by sediment supply...

A laboratory experiment on sand bar migration with comparisons to recent models

Creator:

Magalen, Jason

Abstract:

Successful prediction of nearshore sediment migration is important in determining the vulnerability of a coastline. During energetic wave climates (storm events) sediment rapidly erodes from beaches and is deposited offshore. In subsequent milder wave conditions, the sediment migrates shoreward, accreting on the beach and helping to protect the coastline. It...
