Water Quality and Sediment Evaluation for Inner Harbor Navigation Canal Lock Replacement Project, New Orleans, Louisiana

摘要

The U.S. Army Corps of Engineers, New Orleans District has been authorized by Congress to replace the existing Industrial Canal Lock. The existing lock has been in operation since 1921, and a new, larger lock would accommodate a heavier traffic load and modern deep-draft vessels. As part of the construction project, sediment and soil from the area will be dredged to accommodate the new lock, allow ship traffic to bypass the construction site, and deepen the current channel through the Inner Harbor Navigation Canal (IHNC). This document summarizes the sediment characterization and environmental analysis conducted in support of the IHNC lock replacement dredging project.
