MOVING SANDS-EQUILIBRIUM STATE OF CRENULATED COASTS
MOSES
PTDC/GEO-GEO/3981/2012
Background and rationale
The knowledge on coastal processes is
not only of basic and practical
importance, for instance in engineering
applications but also of socioeconomic relevance. In a crenulated
coastline with beaches and headlands,
the balance between the incoming
and the lost sediment determines the
beach stability that ranges between
dynamic equilibrium to unstable.
Headlands are natural barriers to the
alongshore drift and therefore reduce
the amount of sediments incoming
from the updrift adjacent beaches.
