Abstract

Sediment samples and beach profile evolution data, collected along one profile line at "El Puntal" Spit, Santander, Spain, are studied by means of Principal Component Analysis (PCA). This analysis technique is used to separate the temporal, spatial and grain size distribution variability of the data. The results show that there is a seasonality in the grain size distribution affecting the fine sand as well as the coarse sand. The variations of the coarse sand percentage, which occur mostly within the bar-berm area, consist of an increase, in the bar zone in winter and in the berm zone in summer. The fine sand presents a different behaviour, changing all along the profile, increasing its percentage offshore the bar in winter, and in the foreshore in summer. Thus, the sediment just relocates in the cross-shore direction.
