Scenarios for Coastal Flooding Caused by Sea Level

Scenarios for Coastal Flooding Caused by Sea Level Rise Southern California Beach Processes Study R. Guza, R. Seymour, W. O’Reilly, R. Bucciarelli, J. Thomas USACE

Projected sea level rise 1990 to 2100, excluding effects from potential ice sheet collapse. -Climate Change 2100, IPCC Third Assessment Report, “The Scientific Basis”

Elevation data collected during Spring 2006 topographic LIDAR survey is used for inundation estimates.

Selected sites in San Diego County were chosen to show different scenarios portraying the effects of sea level rise.

Oceanside * Effects of waves, El Niño, storm surge, and beach sand level change are not included.

Del Mar * Effects of waves, El Niño, storm surge, and beach sand level change are not included.

La Jolla Shores * Effects of waves, El Niño, storm surge, and beach sand level change are not included.

Mission Beach & Bay * Effects of waves, El Niño, storm surge, and beach sand level change are not included.

Point Loma * Effects of waves, El Niño, storm surge, and beach sand level change are not included.

Coronado * Effects of waves, El Niño, storm surge, and beach sand level change are not included.

Imperial Beach * Effects of waves, El Niño, storm surge, and beach sand level change are not included.

The Southern California Beach Processes Study (SCBPS) is designed to improve our understanding of beach sand transport by waves and currents, thus improving local and regional management of sandy shorelines. Changes in beach sand level, and the waves causing those changes, are monitored over portions of the Southern California shoreline. The observations are provided to agencies concerned with beach management. http: //cdip. ucsd. edu Email: www@cdip. ucsd. edu
