Waihee-Waiehu, HI Coastal Erosion Rate
Shoreline change 1.7 miles southeast of Waihee-Waiehu, HI
Nothing alarming measured 1.7 miles southeast of Waihee-Waiehu, 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 "Waihee-Waiehu" means on this page
Waihee-Waiehu, HI is the nearest named place, 1.7 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: 20.91, -156.49. 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.
How solid is this number
212 transects feed this segment's number; 88% of them individually measured retreat. Uncertainty on this specific number: 0.15 ft/yr either side. The unadjusted figure here, -0.14 ft/yr, would place it 583 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. Copalis Beach, WA sits at national rank 1105 for growth (0.99 ft/yr), one reference point among the 1211 scored segments, 2557 miles from here. 1.8 miles up the coast, Waihee-Waiehu, HI shows the same lack of a significant trend.
