Impact/Purpose:
Provide distribution of a suite of peer-reviewed, tested and supported models to customers via the internet, free of charge. Provide training opportunities via the environmental education program for learning about environmental protection, modeling, modeling applications, and the models distributed by CEAM. When appropriate and requested, CEAM personnel provide site-specific application support.
Description:
A sediment and contaminant transport model and its application to the Maurice River-Union Lake system in southern New Jersey, USA is described. The application is meant to characterize and forecast sediment and arsenic (As) distributions before and after proposed dredging activities. The model, HSCTM-2D, is a two-dimensional, depth-averaged, finite element code capable of simulating the hydraulics of both steady and unsteady surface water flows, cohesive and cohesionless sediment transport, and the transport and fate of inorganic contaminants. Interactions between dissolved (i.e., desorbed) and particulate (i.e., adsorbed) contaminants and sediments are accounted for by simulating the processes of adsorption and desorption of contaminants to and from sediments, respectively. Four model simulations yielded (As) flushing times ranging from 25 years for the "no action" scenario to four years for dredging of contaminant bed sediments in the Maurice River and Union Lake.
