ASSESSING KARST HAZARDS AND MASS WASTING RISKS IN PULASKI COUNTY, KENTUCKY: PERSPECTIVES FROM THE APPALACHIAN TERRAIN

In this project, we utilized high resolution (1.5 meter) Light Detection and Ranging (LiDAR) Digital Elevation Model (DEM) data to identify karst hazards, specifically focusing on potential mass wasting events. Our aim was to uncover the locations of these hazards. Thus far, we have generated a mosaic of data tiles of downtown Somerset in Pulaski County and the entirety of Pulaski County within the Appalachian region of Kentucky. From this mosaic, we produced hillshade and slope maps illustrating varying degrees of elevation and steepness of hills and knobs. These maps were also enhanced by using color to accentuate target features. Through this methodology, we identified multiple locations of slope hazards and a plethora of sinkholes. It is crucial to identify these karst and slope features because there are many homes and businesses in this area that could be damaged due to these hazards. Furthermore, the hazards pose a public safety concern for those working, residing, and traveling in the area. Our next step involves taking rock and soil samples from identified locations based on LiDAR DEM analysis for petrographic analysis to find insights into slope stability and landslide potential by determining the exact composition of slope-forming materials. Ultimately, the findings of this project will inform strategies to protect critical assets and improve the well-being of rural Appalachian households, promoting local awareness.
