The DMMP investigated the fate and transport of dredged material placed at the dispersive dredged material placement sites within the Strait of Juan de Fuca and Puget Sound using site specific sediment data and a recent numerical model developed for the Puget Sound Basin. This study, completed in September 2012, was to determine if hydrodynamic conditions indicated the potential for dredged materials to be transported in the vicinity of critical shellfish habitat identified by the Lower Elwha Klallam Tribe (LEKT) near Port Angeles, Sequim, and Port Townsend, Washington.
