Backshore coarsening processes triggered by wave-induced sand transport : the critical role of storm events

Auteur(s) et Affiliation(s)



Description :
This study aims to demonstrate that backshore processes at a sandy beach facing the Pacific Ocean in Japan are a result of both wave and wind actions. This is achieved through a field analysis of the beach topography and sand grain size; the backshore profile and cross-shore distribution of the median sand grain size in 1999 and 2004 are compared. Further, this study aims to elucidate the mechanisms involved in backshore processes through numerical analysis in terms of a uniform parameter that can be applicable in the case of both water and air, i.e. the threshold movable grain size, in the cross-shore direction.
