Landslide monitoring project at Maxey Flats Disposal Site

Landslide Monitoring at Maxey Flats Disposal Site, Kentucky The Maxey Flats Disposal Site is a low-level nuclear waste disposal facility in Fleming County, Kentucky. Although no longer accepting waste for burial, the facility continues to maintain the construction cap, evaluate the site drainage system, and monitor hillslope erosion. Several landslides have been documented along the slopes below and adjacent to the facility cap. The Kentucky Geological Survey (KGS) plans to use a small Unmanned Aerial Vehicle (UAV), equipped with LiDAR acquisition capability, to monitor slopes and document any potential slope movement. The KGS will plan the flight missions, conduct the flights, and process the LiDAR data. We will assess slope movement by using generated digital elevation and hillshade models. Flights will occur quarterly in order to conduct elevation differencing and quantify slope movement over time. Maxey Flats officials will use the data and results to support drainage and hillslope stabilization techniques, address security of the cap, and assist with site hazard and risk assessment.
