| Summary: | <p>Sandy beaches are unique environments composed of unconsolidated
sediments that are constantly reshaped by the action of waves, tides,
currents, and winds. The most seaward region of the dry beach, referred to
as the beach face, is the primary interface between land and ocean and is of
fundamental importance to coastal processes, including the dissipation and
reflection of wave energy at the coast and the exchange of sediment between
the land and sea. The slope of the beach face is a critical parameter in
coastal geomorphology and coastal engineering, as it is needed to calculate the
total elevation and excursion of wave run-up at the shoreline. However,
datasets of the beach-face slopes along most of the
world's coastlines remain unavailable. This study presents a new dataset of beach-face slopes
for the Australian coastline derived from a novel remote sensing technique.
The dataset covers 13 200 km of sandy coast and provides an estimate of the
beach-face slope every 100 m alongshore accompanied by an easy-to-apply
measure of the confidence of each slope estimate. The dataset offers a
unique view of large-scale spatial variability in the beach-face slope and
addresses the growing need for this information to predict coastal hazards
around Australia. The beach-face slope dataset and relevant metadata are
