Water level forecasts

CDIP water level forecasts estimate the vertical elevation to be reached for a given coastal location, using a simple, computationally fast model that requires little information beyond wave conditions.


The Coastal Flooding Reporting Tool originally developed by PacIOOS and funded by Sea Grant has been re-purposed to help record flooding events up and down the California coast. This tool is open to the public. We encourage everyone to submit photos and text of flooding events in their area.

POLB Marine Exchange

CDIP provides a summary of wave conditions from 3 local buoys for the Port of Long Beach Marine Exchange.


Tsunami events recorded by CDIP's Scripps pier pressure sensor from October 1994 to the present.

Coastal photo database

Since 2010 CDIP has been taking geo-tagged photos of the coastline from Imperial Beach to Dana Point by piggy-backing on yearly Coast Guard Helicopter missions. This photographic database provides a record of coastal change over the years.


The network of CDIP wave buoys on the east coast of the United States have recorded a number of hurricane events from August 2007 to the present.


The Southern California Coastal Ocean Observing System is one of eleven regions that contributes to the national U.S. Integrated Ocean Observing System (IOOS).


The Southern California Beach Processes Study (SCBPS), sponsored by the U.S. Army Corps of Engineers and the California Department of Boating and Waterways, is monitoring and modeling beach erosion, and providing the knowledge base for more effective local and regional beach management.

Ongoing observations of beach erosion and accretion (obtained with LIDAR, personal watercraft, all terrain vehicles, and hand-pushed dollies) are available to beach management agencies, and are used by SCBPS scientists to test and develop models for beach erosion.
