14. ABSTRACT
This data review for Humboldt Bay, CA, was conducted by GDC, LLC, Trinidad, CA, for the U.S. Army Engineer Research and
Development Center (ERDC), Coastal and Hydraulics Laboratory (CHL), Vicksburg, MS. The report was prepared by Dr. Steven L.
Costa and Dr. Karen A. Glatzel, GDC, under the general direction of Dr. Adele Militello, Coastal Hydrodynamics Branch (CHB), CHL.
Work was performed under the Inlet Modeling System (IMS) Work Unit of the Coastal Inlets Research Program (CIRP), Headquarters,
U.S. Army Corps of Engineers (HQUSACE).
CHL is conducting a study of the entrance to Humboldt Bay, CA, as a part of CIRP. This data review provides a supplementary
inventory and review of available data to support the study. The data review includes historical and recent physical processes and
engineering data describing Humboldt Bay and the adjacent littoral cell. The focus is on data and data sources related to physical
oceanography (tides, wind, waves, currents, hydrographic structure, bathymetry), coastal processes, tidal inlet and beach dynamics, sand
supply and budgets, structural modifications controlling the inlet, and dredging.
