Simulation of effects of contour coal strip mining on stormwater runoff and pollutant yields
A set of mathematical models was derived and evaluated on 5 years of runoff and pollutant data in the New River, Tennessee. The six watersheds used in the study ranged in size from 429 to 2765 acres. All but one watershed had been or was undergoing contour coal strip mining. The remaining watershed was in 100% forest. The models consisted of a storm hydrograph simulator, a watershed pollutant load simulator and a site erosion simulator. The storm hydrograph simulator, TENN-I, has been optimized on numerous agricultural and urban watersheds in the Tennessee Valley. The watershed pollutant load simulator, LOAD-I, was based upon development of a mass balance that was derived from storm hydrographs and pollutographs. The soil erosion model, ERODE-I, was based upon soil erosion mechanics and overland flow. Erosion, runoff, and pollutant loads were simulated for storm bases. A regionalization scheme associated with the model permitted simulation of the effects of contour coal strip mining on stormwater and pollutant load.
