Estimating Contaminant Losses During Dredging

Category:

Contracting Procedures

Description:

The Corps of Engineers has performed intensive monitoring of dredging operations for a number

of sites and has correlated sediment resuspension to dredge operating characteristics, sediment

characteristics, and site conditions. Mathematical formulas to estimate the mass rate of sediment

entering the water column at the point of dredging have been developed for cutterhead dredges

and bucket dredges. A computer program using the Windows3.1 operating system has been

written to calculate and graphically display contaminant losses and water column concentrations

using predictive techniques.

The program (currently named DREDGE) allows the user to enter the necessary dredge

information, site characteristics, operational data, and contaminant characteristics, then calculates

an array of concentration values, including suspended sediment concentrations, total contaminant

concentrations, dissolved contaminant concentrations, and particulate contaminant

concentrations. DREDGE is currently a module of ADDAMS, and available from WES.
