Fate and Transport of Metals in a River System

Document Type: Proceeding Paper

Part of: Environmental Engineering

Abstract:

A steady-state model was developed that describes the fate of metals in a shallow river system. Settling and resuspension of solids were defined through empirical equations relating a net sediment transport rate to average stream velocity. Adsorption and desorption kinetics were simulated based on inverse relationships formulated between suspended solids and partition coefficients. The model was successfully calibrated for two independent water quality surveys and validation was indicated from analysis of a third survey. (Author abstract. )
