The goal of
this joint program between the University of California, Scripps
Institution of Oceanography, and the Bureau is to understand beach
processes in Southern California, especially the relationship between
ocean waves and changes in beach sand level. The specific objective
of the Bureau is to collect topographic data along the coast from
Point La Jolla to Dana Point and develop new methods of shoreline
mapping using airborne lidar technology. Lidar surveys were conducted
in May, September, and December of 2002 during periods of low tide.
Besides mapping the shoreline and beach, we flew lidar passes offshore
to map the sea-surface topography for comparison with computer model
estimates of wave and swell heights. All these data are being analyzed
at Scripps and at The University of Texas at Austin.
