Quaternary and Surficial Geologic Mapping for Geotechnical and Geohazards Applications in Kentucky

This proposal is seeking $299,078 to support new surficial geologic mapping in Kentucky, in areas which have been identified by the Kentucky Geologic State Mapping Advisory Committee as priority areas that need more detailed surficial geologic mapping to meet societal needs. This proposal includes two one-year projects intended to support the long-range goals identified by the SGMAC. Project 1 proposes new Quaternary geologic mapping in two 7.5-minute quadrangles in the Western Kentucky Coal Field in Muhlenberg County, Kentucky, to support seismic hazard assessment, geotechnical planning, and water supply development. This will expand recent Quaternary geologic mapping projects in this region and will allow development of future derivative products for local government officials and agencies. Kentucky's energy plan supports the development of coal-conversion plants, which likely will be sited near the Green or Pond Rivers in the Western Kentucky Coal Field to take advantage of the river's water supply, transportation capacity, and adjacent inexpensive coal supplies. This mapping will enable informed site selection and construction planning for these facilities. Project 2 proposes new surficial geologic mapping of the Kentucky portions of four 7.5-minute quadrangles in landslide-prone areas of Eastern and Northern Kentucky. Landslides are a major cause of property loss and infrastructure damage in this area. Detailed geologic mapping of surficial materials, including colluvium, and differentiation of alluvium in valley fills will assist state and local decision makers as they pursue infrastructure construction and economic development for the region.
