Models to predict environmental impact of mine drainage on streams

This report summarizes the results of an inter-disciplinary effort to develop and apply water quality and hydrologic models to streams affected by mining activities. The objective of the overall study was to evaluate environmental degradation due to acid drainage and sediment runoff from mined areas. The end result was the application of various models to predict the impact of mine drainage on the stream system. This paper summarizes the development of hydrologic and water quality models which were used to predict the impact of mine discharges on the physical-chemical environment of the stream.
