20230302 09015300 1.0 TRUE Areas susceptible to debris flows This layer (lines) represents debris flow deposits or areas susceptible to debris flows. Primarily these areas are shallow, narrow ravines containing variable accumulations of colluvium. The data come from a series of Landslide and Related Features Maps and Landslide Potential Maps that cover most of southeastern and south-central Kentucky. The features were interpreted from aerial photographs and historical records. The debris flows digitized depict generalized slope conditions as they existed at the time of field checking (1977-1981). Areas of thick colluvium are susceptible to rapid movement during intense rainfall. The data are from preliminary type maps and are suited for general planning purposes only.
