Los Angeles/Long Beach, CA
Harbor
Description
Wave and water-level measurements have been directed by CHL for Corps of Engineers
District, Los Angeles (CESPL) and
the Ports of Los Angeles and Long
Beach (LA/LB) since 1984. The
most recent LA/LB harbor
monitoring system includes twelve
wave and water-level gauges in and
around LA/LB harbors. Collected
data are used in design considera-
tions for harbor modifications.
An increase of harbor operations
Issue
created the need for additional
mooring areas within the two
harbors. Modifications have resulted
in extensive expansion and
modification of the LA/LB harbors.
The Field Data Collection and
Analysis Branch operates and
maintains a system of wave gauges, located at strategic places in the harbor to assist
CESPL in assessments of impacts of channel modifications, dredging operations, and
breakwater performance; and, to help the Ports of Los Angeles and Long Beach determine
the best location, orientation and configuration for required pier enhancements.
Products
Near-real-time wave, water level and surge data are provided via the Internet for all
locations. Statistical summaries are provided annually. Data and additional information
Near-real-time wave and water-level data are acquired using in-water gauges that transmit
Supporting Technology
data to shore using underwater cable and radio telemetry. Data are automatically
transmitted to the Coastal and Hydraulics Laboratory via the Internet.
Harbor wave and water-level data provide CESPL and the Ports information for evaluation
Benefits
of hydrodynamic characteristics of the harbors and assists in decisions concerning pier
construction, location, orientation and configuration. Measured data are used to calibrate
and validate physical and numerical models.
