Transport model to predict the movement of Pb, Cd, Zn, Cu, and S through a forested watershed. [Heavy metal concentrations in soils and surface waters adjacent to Pb mine and smelter]
Two versions of the Unified Transport Model (UTM) have been used to simulate movement of Pb, Cd, Zn, Cu, and S through the Crooked Creek Watershed, a 1.3 mi./sup 2/ forested headwaters area adjacent to a Pb mine and smelter in southeast Missouri. The Wisconsin Hydrologic Transport Model (WHTM) version was used to study accumulation of heavy metals in the soil and to simulate stream flow and heavy metal concentrations in the stream draining the watershed. The Terrestrial Ecology and Hydrology Model (TEHM) version was used to study heavy metal and SO/sub 2/ effects on the vegetation by considering plant uptake in a plant growth and decomposition model. The Soil Chemical Exchange of Heavy Metals (SCEHM) submodel in TEHM was used in a detailed comparison between results from a six-year simulation of heavy metal accumulation in the top soil layers and measured values. Agreement between simulated results from both versions of the UTM and measured values is satisfactory.
