Sarita, TX Coastal Erosion Rate
Shoreline change 25.7 miles east of Sarita, TX
25.7 miles east of Sarita, TX, the coast is advancing, not retreating, at a measured 0.58 feet a year, sediment accumulating faster than any erosion USGS recorded here. At that rate, the shoreline has gained roughly 5.8 feet over the last decade.
What "Sarita" 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 Sarita, TX, rather than showing one arbitrary line. Segment center: 27.24, -97.38. The survey behind it runs to 2001, in USGS's Gulf of Mexico assessment, using the LRR 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 0.58 ft/yr means over time
Holding the 0.58 ft/yr accretion rate 25.7 miles east of Sarita, TX for 25 years would add roughly 14 feet of shoreline, again assuming nothing about the local sediment supply changes.
How solid is this number
Averaging 63 separate transects produced this segment's rate, with 0% individually reading as erosion, rather than relying on any single survey line. Uncertainty on this specific number: 0.42 ft/yr either side. This segment ranks 1038 of 1211 measured US coastal segments, ordered from fastest erosion to fastest growth. Source: USGS Open-File Report 2004-1089. Albion, CA sits at national rank 963 for growth (0.3 ft/yr), one reference point among the 1211 scored segments, 1725 miles from here. 1.8 miles away, Sarita, TX is the nearest other measured stretch: also no significant trend.
