It has been shown that engineering experience and performance histories of earthwork structures and foundations in distinctive physiographic regions provide valuable insights applicable to the planning and construction of future projects. Geologic information further categorizes earth materials on the basis of parent material and geologic processes which modify the rock and soil masses. A knowledge of the resulting topographic expression or landforms and reference to geologic and soils information contained in surveys, reports, and maps is particularly useful in the early stages of planning and site selection. When sufficient information is available, regional units may be recognized for the purpose of delineating engineering behavior of the earth materials. Such regional approaches have been demonstrated to be valid for the State of Kentucky in recognizing certain areas which are potentially hazardous with the regard to landslides and engineering performance of soils.
