Kalaeloa, HI Coastal Erosion Rate
Shoreline change 1.9 miles southwest of Kalaeloa, HI
Nothing alarming measured 1.9 miles southwest of Kalaeloa, 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 "Kalaeloa" means on this page
Kalaeloa, HI is the nearest named place, 1.9 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: 21.30, -158.09. Survey years: 2007-2010, method WLR, from USGS's Hawaii shoreline-change assessment. That's how current the data is here, real, but not a live feed, since a shoreline survey is a major undertaking, not an annual check-in.
Where this fits nationally
This reading comes from 78 individual transects averaged together, 23% of which measured erosion rather than growth. The published margin on this reading runs ±0.23 ft/yr. The unadjusted figure here, 0.05 ft/yr, would place it 819 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. Gardiner, OR sits at national rank 1045 for growth (0.59 ft/yr), one reference point among the 1211 scored segments, 2482 miles from here. Kalaeloa, HI, 2.3 miles off, is the adjacent measured stretch, itself no significant trend.
