In the Eastern Appalachian Region unique problems are created by the rugged mountainous terrain, necessitating contour mining or mountain top removal mining practices that leave the terrain highly modified. These activities result in a major disruption of the antecedent hydrologic and hydraulic conditions. Infiltration rates, overland flow paths, subsurface flow paths, soils and cover conditions are all modified. No existing modeling technique can adequately describe the topography in terms of the detail topological relationships such that the concentration of water via overland flow and subsurface flow is accurately simulated in space and time. One way of circumventing this shortcoming is to apply a digital terrain model based data management system which, inherently, manages all input parameters and attribute information. The data management system is built around an irregular triangulated grid digital terrain features such as ridge lines, slope representing all terrain features such as ridge lines, slope breaks, streams and channels; and in the case of a mining site, high walls, pits, spoil piles and access roads. In addition, attribute data such as soils, land use, vegetative cover and geology are included. A most effective component of the system interactive hydrologic modeling system is to be developed with substantial use of computer graphics to display output data in easily interpretable form.
