Utilization of the Kinematic Runoff and Erosion Model in Predicting the Effects of Veg- Etation on Heavy Metal Contain- Ment in Southeast Kansas

In southeast Kansas, where mining activities ceased in the middle half of the twentieth century, heavy metals in residue materials have created surface contamination problems. The erosion losses of chat material, a by-product of mining activities, have elevated levels of cadmium, lead, and zinc in nearby farmland to phytotoxic levels for the crops normally planted. Selective vegetation is being examined as a means of controlling the loss of sediment material and containing the further spread of the metal contaminants. The kinematic runoff and erosion model, KINEROS, is examined to investigate the role vegetation plays in controlling erosion from an 800-acre watershed near Galena, Kansas. Results of the model are compared with predictions made by another non-point source model, the agricultural non-point source pollution model, AGNPS.
