Siletz Bay is a drowned river valley filled with Holocene alluvial
and estuarine sediments and is separated from the ocean by a sand
spit 3.8 km in length. Since the area was settled by white man in the
1890's, the bay has apparently experienced rapid siltation, due to
increased farming...
Landsliding is a significant contributor to continuous erosion
of the 150-mile northern Oregon coast. Direct loss of land to the sea
by landslides occurs along 47 percent of the coast. The remaining 53
percent has minor shifting of sand along depositional areas such as
spits and dunes. These minor movements...
Understanding the past, present, and future behavior of our nation's shorelines is vital for sensible coastal management. Localized areas of erosion, termed "erosional hot spots", can shift the shoreline landward threatening coastal infrastructure (Kraus and Galgano, 2001; Stauble and Gravens, 2004; McNinch, 2004). One specific type of erosional hot spot...
Sea-cliff erosion is a significant problem along the Oregon coast in that many
communities have been built on terraces affected by bluff retreat. There is considerable
coast-wide variability in the rates of cliff erosion. This variability is attributed in part to
tectonic activity that is causing differential interseismic uplift along...
The purpose of this research is two-fold: to evaluate the success of the new emergency procedures promulgated in 1998 and to characterize the erosion event that precipitated the emergency during January, February and March 1999. These two purposes support each other and provide a holistic understanding of how emergencies arise...
The community of Bandon is located on the southern half of the Oregon coast, 140 kilometers north of the California border and 40 kilometers south of Coos Bay (Figure 1). Part of the city occupies the low-lying (average 3-meter elevation) area along the south bank of the Coquille River, while...
