ABSTRACT:
The CREAMS model was used to simulate pentachlorphenol concentrations in surface runoff at a site identified by the U.S. Environmental Protection Agency as contaminated. Available data were used and estimates made of input parameters as needed. Simulation results were judged to be reasonable, based on knowledge of observed runoff, erosion, and contamination. The adjustment made to the curve number by the model for soil moisture conditions may have been excessive under semiarid climatic conditions. An analysis of a few chemical parameters showed extreme sensitivity to water solubility under the site conditions.
