Willapa Navigation Study
The study involved collection and analysis of historical hydrographic survey data, field measurements and modeling of waves, currents, and coastal processes including sediment transport. The study identified the estuarine hydraulic characteristics and quanitified long-term erosion trends, and geomorphology of the entrance and adjacent shores. A component of the study involved a prototype study of channel dredging design and response monitoring and modeling in the Bay Center Entrance Channel which has historically experienced rapid shoaling. Study results were published in the reports: N.C. Kraus 2000. Study
of Navigation Channel Feasibility, Willapa Bay, Washington. ERDC/CHL
TR-00-6.

The
Willapa Bay study was initiated to determine the engineering feasibility
of re-establishing and maintaining a safe and reliable navigation channel
through the ocean entrance of Willapa Bay to commercial docks in the
harbor. The study was performed by Pacific International Engineering,
PLLC together with the US Army Corps of Engineers Engineer Research and
Development Center, Coastal Hydraulics Laboratory, and the Port of Willapa
Harbor.
