CoachThe shoreface is the sloping zone seaward of the beach where waves continually rework the sea floor. Its base is the fair-weather wave base, the depth below which ordinary waves no longer move the bottom sediment. The storm wave base is the deeper limit reached by storm waves; between the two, mud settles in calm weather and is reworked into sand beds during storms. Below the storm wave base the floor is undisturbed by waves.
