Gulf Coast Region
Events | Publications | Projects
The Gulf Coast Region includes five states (AL, FL, LA, MS, and TX) that border the Gulf of Mexico, containing 17.2 million acres of marsh and nearly 30,000 miles of shoreline. Many challenges exist in the region due to extreme weather events like hurricanes, subsidence due to tectonic motion or water withdrawal, and rapid coastal development.
Accurate height information can increase efficiency and accuracy of water delivery and drainage systems, improve disaster preparedness, aid ecosystem science or restoration, and improve earthquake detection. Accurate flood plain maps and precision agriculture are also important applications of Height Modernization in the region.

Projects
Gulf Coast Height Modernization Project
Completed in July 2012, this project is in a region of known subsidence spanning southeastern Texas, southern Louisiana, Mississippi, and Alabama, and westernmost Florida. Due to subsidence, many control station elevations in the region are obsolete. New elevations were determined by combining new and old leveling observations using a technique called Vertical Time-Dependent Positioning (VTDP). VTDP compares leveling performed at different times to estimate rates of elevation change, and these rates are used in leveling adjustments to compute updated elevations... more
