Model for the Assessment and Remediation of Sediments Evaluates Active Sediment Caps for Anacostia River Remediation
Implementation of the Model for the Assessment and Remediation of Sediments (EPRI Product 1020624).  The Model for the Assessment and Remediation of Sediments was used to predict and compare the long-term effectiveness of several active sediment caps in the Anacostia River, which flows through the District of Columbia.  Developed by EPRI, it is the only available software to model river hydrodynamics, sediment transport, and chemical fate and transport sequentially in an integrated framework.  The goal of this research was to test the capability of the model to predict the long-term effectiveness of four different subaqueous active capping scenarios.  The research team reviewed available literature on hydrodynamic, sediment transport, and chemical fate and transport modeling, as well as model input parameters.  They developed specific inputs based on previous studies of the Anacostia River and specific studies undertaken for this research.  This report describes results of preliminary simulations.  In the future, these results will be verified by comparison to data obtained from the ongoing field-scale, active capping barrier project under way on the Anacostia River.  For more information, contact Jeff Clock, (845) 608-0642, jclock@epri.com.
