Superduck Beach Sediment Sampling Experiment. Report 1. Data Summary and Initial Observations.

摘要

This report provides a summary of grain size data collected during Phase II (October 1986) of the SUPERDUCK field experiment. The objective of the study was to collect and analyze data on changes in beach sedimentology and morphology associated with major storm event. Average median grain size provided useful information for identifying trends in sediment texture associated with variations in nearshore wave climate. During storm events, finer-grained sand was removed from the subaerial beach profile, producing a coarser average median grain size. Post-storm recovery involved landward migration of the nearshore bar system and a net decrease in average median grain size.
