Barview, OR Coastal Erosion Rate
What USGS measures 1.7 miles northwest of Barview, OR
Unusual good news for this stretch: the shoreline 1.7 miles northwest of Barview, OR has grown by a measured 2.33 feet a year on average, per USGS's long-term transect data for this section. At that rate, the shoreline has gained roughly 23.3 feet over the last decade.
The grain of this number
USGS surveys the coast in transects spaced a few hundred feet apart; this page groups the nearest ones into a single ~3.5-mile reading for the stretch closest to Barview, OR, rather than showing one arbitrary line. Segment center: 43.37, -124.32. USGS's Pacific Northwest assessment last surveyed this stretch through 2002-2011, computing the rate with its LRR method. Other US regions were surveyed in different years, sometimes decades apart, so this page states its own rather than implying one national vintage.
What 2.33 ft/yr means over time
Holding the 2.33 ft/yr accretion rate 1.7 miles northwest of Barview, OR for 25 years would add roughly 58 feet of shoreline, again assuming nothing about the local sediment supply changes.
What backs this reading up
26 transects feed this segment's number; 0% of them individually measured retreat. The published margin on this reading runs ±1.6 ft/yr. Sorted from fastest erosion to fastest growth across all 1211 measured segments nationally, this one lands at 1169. Source: USGS Open-File Report 2012-1008. For scale: Warrenton, OR, 195 miles away, ranks 1196 of 1211 nationally for growth, 4.64 ft/yr, 2.0x this stretch's rate. 1.2 miles up the coast, Barview, OR shows the same lack of a significant trend.
