Hanamaulu, HI Coastal Erosion Rate
Shoreline change 1.1 miles northeast of Hanamaulu, HI
Nothing alarming measured 1.1 miles northeast of Hanamaulu, 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 "Hanamaulu" means on this page
Hanamaulu, HI is the nearest named place, 1.1 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: 22.01, -159.34. The survey behind it runs to 2007-2010, in USGS's Hawaii assessment, using the WLR method. Shoreline surveys aren't repeated every year, so this is the most recent long-term measurement USGS has published for this coast, not a live reading.
What backs this reading up
Averaging 136 separate transects produced this segment's rate, with 90% individually reading as erosion, rather than relying on any single survey line. Uncertainty on this specific number: 0.3 ft/yr either side. The unadjusted figure here, -0.19 ft/yr, would place it 511 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. Rank 1006 nationally for growth belongs to Dana Point, CA, 2646 miles from this stretch, measured at 0.44 ft/yr. 2.1 miles away, Wailua, HI is the nearest other measured stretch: also no significant trend.
