PTM Modeling of Dredged Suspended Sediment at Proposed Polaris Point and Ship Repair Facility CVN Berthing Sites - Apra Harbor, Guam

Abstract

The U.S. Navy is studying alternatives for the construction of a new, deep-water wharf at Apra Harbor, Guam, to provide a berthing site for transient nuclear powered aircraft carriers. The U.S. Army Corps of Engineers, Engineer Research and Development Center was tasked with predicting the fate of resuspended dredged sediment during dredging operations for this port development. One byproduct of dredging is release of suspended material into the water column. This material temporarily increases turbidity during and after the dredging operation. Another byproduct is the deposition of suspended solids on surrounding coral. The Particle Tracking Model (PTM) was applied to evaluate exposure to coral for various dredging alternatives.
