Kawela Bay, HI Coastal Erosion Rate
Shoreline change 2.5 miles southwest of Kawela Bay, HI
Nothing alarming measured 2.5 miles southwest of Kawela Bay, HI: whatever shift USGS's transects picked up here is too small to call reliably one way or the other, which this site reports as "no significant trend" rather than forcing a direction.
What "Kawela Bay" means on this page
Kawela Bay, HI is the nearest named place, 2.5 miles away, to a ~3.5-mile stretch of coast USGS has surveyed - the reading below covers that whole stretch, not a single property in it. Segment center: 21.68, -158.03. USGS's Hawaii assessment last surveyed this stretch through 2007-2010, computing the rate with its WLR 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 backs this reading up
Averaging 116 separate transects produced this segment's rate, with 56% individually reading as erosion, rather than relying on any single survey line. The published margin on this reading runs ±0.13 ft/yr. The unadjusted figure here, -0.01 ft/yr, would place it 761 of 1211 if ranked directly - but an unreliable rank isn't a useful one, which is exactly why "no significant trend" is the headline instead. Source: USGS Open-File Report 2011-1009. For scale: Redondo Beach, CA, 2547 miles away, ranks 1030 of 1211 nationally for growth, 0.53 ft/yr. Kawela Bay, HI, 2 miles off, is the adjacent measured stretch, itself no significant trend.
Not this whole stretch, just Kawela Bay itself: the Coastal Change Hazards Portal is USGS's own live version of this data.
