ABOUT APPALACHIAN REGION TECHNOLOGY TRANSFER
Technology transfer provides critical support to current programs in the following ways:
TROMPE - Powered Passive Aeration of Mine Water
There were two guided tours highlighting the TROMPE and the passive treatment system, one from 10:00 am to 12:00 pm and another from 1:00 pm to 3:00 pm.
The event was open to the public and was held on
Tuesday, June 18, 2013.
This manual was generated because of a clear need within the Appalachian Region to create more effective photographic images tailored to the ultimate use and effectively manage, disseminate, and electronically store these images.

Evaluating SEDCAD Model Performance on Reclaimed Coal Mine Lands in East Tennessee by Siavash Hoomehr, and John S. Schwartz
Journal of Irrigtation and Drainage Engineering © ASCE / MARCH 2013, 139:261-266
This paper reports findings from the 2008 Applied Science Project titled "Reforestation of Steep Reclaimed Slopes: Stability and Sediment Control Considerations". This study compared sediment yields from three surface coal mining sites in east Tennessee with SEDCAD modeled outputs. Study sites included active mining operations on steep slopes (>20°) where after mining, approximate natural hillslope contours were reconstructed by using loose spoil materials on top of slope, at shallow depths of 1–2 m, following the Forest Reclamation Approach. The SEDCAD model inputs included the site-derived hydrologic curve number (CN) of 59 and average erodibility K factors ranging from 0.001–0.034 Mg · ha · h · ha-1 · MJ-1 ·mm-1 varying on the basis of pre- and postrill development periods and mining site. The SEDCAD overestimated sediment yields as a function of erosivity (R) up to 1.6 times greater than the minimally measured yields in two of the three study site
Defining Manganese(II) Removal Processes in Passive Coal Mine Drainage Treatment Systems Through Laboratory Incubation Experiments
The presence of elevated concentrations of Mn(II) in coal mine drainage (CMD) is a significant problem for many regions in the USA and throughout the world. In Appalachia, centuries of coal mining have left thousands of abandoned mines that are discharging metal-contaminated CMD with Mn concentrations as high as 150 mg/L (Herlihy et al., 1990; Cravotta, 2008).
