Seadrift, TX Coastal Erosion Rate
Shoreline change 12.5 miles southeast of Seadrift, TX
Good news, and an honest one: USGS's data can't distinguish this stretch, 12.5 miles southeast of Seadrift, TX, from a flat trend. Whatever small movement it measured here is statistical noise, not a reliable direction, so none is claimed.
What "Seadrift" means on this page
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 Seadrift, TX, rather than showing one arbitrary line. Segment center: 28.26, -96.60. USGS's Gulf of Mexico assessment last surveyed this stretch through 2001, 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.
How solid is this number
99 transects feed this segment's number; 0% of them individually measured retreat. Uncertainty on this specific number: 1.38 ft/yr either side. The unadjusted figure here, 0.94 ft/yr, would place it 1097 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 2004-1089. Sarita, TX sits at national rank 1108 for growth (1 ft/yr), one reference point among the 1211 scored segments, 91 miles from here. Seadrift, TX, 1.8 miles off, is the adjacent measured stretch, itself no significant trend.
