Description:
This paper describes a sediment and contaminant transport model and its application to the Maurice River-Union Lake system in southern New Jersey, USA for the purpose of characterizing and forecasting sediment and arsenic distributions before and after proposed dredging activities. The model, HSCTM-2D, is a two-dimensional, depth-averaged finite element model capable of simulating the hydraulics of both steady and unsteady surface water flows, cohesive and cohesionless sediment transport, and the transport and fates of inorganic contaminants, specifically metals and metalloids. Interactions between dissolved (i.e., desorbed) and participate (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 flushing times ranging from 15 years for the "no action" scenario to 4 years for dredging of contaminant bed sediments in the Maurice River and Union Lake.
