英文摘要	Shorelines respond to a number of “drivers” operating on a variety of time-scales. For some time-scales (e.g., seasonal), the driver-shoreline relationship is often evident; however, at longer time-scales (e.g., multiannual), the shoreline changes may be superimposed on changes at shorter time-scales and thus are diﬃcult to identify. Here, we predict shoreline evolution from storm events to decadal time-scales, using a novel approach based on the Complete Ensemble Empirical Mode Decomposition. This approach identifies and links the primary time-scales in the model drivers (large-scale sea level pressure [SLP] and/or waves) with the same time-scales in the shoreline position. The multiscale approach reproduced shoreline changes at two beaches more skillfully than a common shoreline model when SLP and wave information were used in combination. In addition, the analysis can be applied to climate indices, providing the opportunity to link longer time-scales with climate patterns (e.g., El Niño Southern Oscillation). © 2020.
