Atmospheric-hydrodynamic coupling in the nearshore

Natural beach shorelines commonly present morphological rhythmic or non‐rhythmic features of varying geometrical characteristics. Traditionally, their formation is believed to be due to wave‐induced processes, a line thoroughly investigated during the last few decades. However, these natural beach formations are frequently bounded by coastal cliffs (or capes) and are affected by intense winds, a fact not previously considered. This paper presents the results of a field survey, demonstrating the existence of atmospheric‐hydrodynamic coupling in the nearshore region outside of the breaking zone at Carchuna beach (Motril, Spain), where the atmospheric conditions are influenced by a lateral geographic obstacle (Cape Sacratif).
