This picture was taken at low tide, looking west (open sea in the distance). In the foreground is a small tidal channel: water from the ebb tide is flowing towards the camera. Behind the channel is the steep lee face of a large sand dune or bar. Its gentle stoss face forms most of the upper part of the picture.

  • During flood tide, does the bar migrate towards or away from the camera?
  • Draw a sketch cross section through the bar, showing the likely internal structure.

Scale: The trowel (outlined) is 30 cm long

Grid reference: from 864 286
