Abstract

Geomorphic reclamation designs applied in western United States, Australia and Spain have reported success quantified by the economic, ecological, and hydrological benefits. Recent research suggests the feasibility of geomorphic principles in a steep humid environment (e.g. West Virginia). The primary objective of this work is to develop a reclamation alternative with geomorphic landform design principles for the coarse coal refuse pile at Royal Scot in Greenbrier County, WV. The reclamation design is based upon currently accepted engineering methods and promotes stormwater runoff, minimizes infiltration through the refuse pile, and is erosively stable. Design features include the following: (1) stormwater time of concentration was minimized using a radial hydraulic network; (2) significant infiltration reduction is expected resulting from the hydraulic barrier; (3) channel sediment transport is resisted by properly sized lining material; (4) prompt flow channelization minimizes overland flow reducing mass wasting effects; and, (5) growth media consisting of soil amendments mixed directly with the coal refuse. Significant reductions in water treatment costs are expected after construction is completed. Extended documentation of water treatment costs, site hydraulics, and noticeable erosion will prove useful to the scientific community providing a case study for future reclamation activities. If the application is proven successful, geomorphic landforming techniques may be considered for other large earthen applications such as other mining operations, landfills, dams, linear transportation projects, and commercial development.
