Airflow and sand transport variations within a backshore-parabolic dune plain complex : NE Graham Island, British Columbia, Canada

Auteurs :
ANDERSON, J.L.
WALKER, I.J.

Description :
This study provides detailed measurements of airflow, sand transport (via saltation and modified suspension), vegetation density, and surface elevation changes over an extensive swath of a backshore foredune-parabolic dune plain complex. Sediment properties reflect variations in near-surface flow and transport processes. In addition, seasonal measurements of sediment deposition via suspended grainfall are presented, and implications for net sediment transport and dune maintenance are discussed.
