Abstract:

Procedures and general results are presented of a recent study performed to estimate the average annual sediment delivery (sand sizes and larger) from sources discharging to the southern California coastline, and to quantify the historic daily sediment discharge from these same sources for the period 1920 to 1985. The mechanisms controlling sediment delivery are discussed, the significance of the numerous sediment sources are determined, and the effects of lagoons, marshes and regulation on beach sand supply are evaluated.
