Abstract:

This project measured and assessed the surface stability of the portion of LA Highway 70 that is ; potentially vulnerable to the Assumption Parish sinkhole. Using Global Positioning Systems (GPS) ; enhanced by a real-time network (RTN) of continuously operating reference stations (CORS), the ; Center for GeoInformatics (C4G) at Louisiana State University (LSU) has collected the horizontal and ; vertical positions for control points located along the Highway 70 corridor between Bayou Corne (in ; the west) and Bayou Choupique (in the east). Measurements were collected between September 2012 ; and June 2013. Data has been processed and made available to LA Dept. of Transportation & ; Development (DOTD) via an Internet FTP site maintained by C4G. During the report’s measurement ; period, no movement attributable to the sinkhole has been detected on Highway 70. The GPS ; measurements did exhibit variability typically associated with random and systematic error. In order to ; capture more accurate, precise, and consistent positions, a permanent monitoring solution is ; recommended.
