“…There is a regulatory emphasis on minimizing stream burial, perceived cost is high, and the steep youthful terrain is difficult to work in (Michael et al, 2010). Continued research has shown that difficulties associated with steep slopes and stability (both channel and hillslope) are valid when minimizing the area of impact , and methods have been developed to overcome some of these challenges (e.g., Sears et al 2014;Michael et al, 2015;. This work presents a demonstration reclamation design involving geomorphic principles for an abandoned coarse coal refuse pile in southern West Virginia.…”

Geomorphic landform design is a reclamation technique that may offer opportunities to improve aspects of mine reclamation in Central Appalachia. The design approach is based on constructing a steady-state, mature landform condition and takes into account the long-term climatic conditions, soil types, terrain grade, and vegetation. Geomorphic reclamation has been applied successfully in semiarid regions but has not yet been applied in Central Appalachia. This work describes a demonstration study where geomorphic landforming techniques are being applied to a coarse coal refuse pile in southern West Virginia, USA. The reclamation design includes four geomorphic watersheds that radially drain runoff from the pile. Each watershed has one central draining channel and incorporates compound slope profiles similarly to naturally eroded slopes. Planar slopes were also included to maintain the impacted area. The intent is to reduce infiltration rates which will decrease water quality treatment costs at the site. The excavation cut and fill volumes balanced to approximately 250,000 yd 3. This volume is comparable to those of more conventional refuse pile reclamation designs. If proven successful then this technique can be part of a cost-effective solution to improve water quality at active and future refuse facilities, abandoned mine lands, bond forfeiture sites, landfills, and major earthmoving activities within the region.
