Amite and Comite Rivers, Denham Springs, LA
During the summer of 2016, more than 3 feet of rain fell in a 48 hour period in/around Baton Rouge, LA. Lowe Engineers was given a large task order to perform automated hydrographic and topographic surveys of the Amite and Comite Rivers, and many of the tributaries to provide H&H design engineering with flood control data. Although primarily a hydrographic survey, the upper regions of the Amite and the Comite Rivers water proved to be too shallow for conventional hydrographic data to be collected. Cross- sections work conventionally collected hydrographically every 250’ for approximately 60 miles until the water became too shallow to survey. Our survey crews then set 15 ground control points along a 6-mile portion of the Amite River as a “pilot”. Lowe combined field hydro surveys with field topo surveys, with U.A.V. flown data, to provide a f inal product to the Corps. The overall length of the project was 110 nautical miles from Watson, Louisiana to the confluence of the Amite River into Lake Maurepas. Our survey efforts were in response to the major flood event that occurred in August 2016.
