Reconstructions and projections of shoreline positions using the Bruun rule exemplified at site #1 (See Supplementary materials 1, 3 and 4), provided in the form of median and percentile levels at different timeframes from 1807 to 2200. The reference median shoreline position is arbitrarily set to 0 by 2000, with negative values corresponding to shoreline accretion (seaward) and positive to shoreline retreat (landward). These projections include uncertain shoreface slopes, vertical ground motions, sea-level changes, shoreline and change variability from event-scale to inter-decadal timescales as well as an uncertain multi-decadal trend (see Methods). Note that sea-level projections used here³² consider that a sea-level drop is possible (although very unlikely) beyond 2100 (Fig. 1). Hence, shoreline changes below the median can bend downwards beyond 2100.
