Bayou Corne Sinkhole: Control Measurements of State Highway 70 in Assumption Parish, Louisiana

This project measures and assesses 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 th e west) and Bayou Choupique (in the east). Measurements were collected between September 2012 and June 2013. Data has been processed and made available to the Louisiana Department 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.
