Abstract:

During the past half-century, the beaches in the central and southern portions of Santa Monica Bay have been significantly enhanced by a combination of artificial nourishment and structural compartmentalization. Approximately 22.2 million m³ of fill have been added, while littoral transport rates and sediment losses down a submarine canyon have been reduced by a series of breakwaters, jetties, and groins constructed in the littoral zone. Although a number of the earlier projects caused unanticipated adverse impacts, the cumulative effect has been to create relatively wide, stable beaches in an area that was formerly starved for sand.
