| Abstract | Where headlands are spaced along a sedimentary coast, the shoreline between the headlands will assume a crenulate shape if the most persistent or predominant waves have a resultant direction which is oblique to the headland alignment. Finally a shape is reached which is in equilibrium
with the waves. This occurs when the incoming waves break simultaneously around the periphery and there is no further longshore drift. The eventual development of such an equilibrium shaped bay was
studied by means of a model in which wave directions and heights were the sole variables. Thus the wave period, water depth, beach height and
sedimentary material were the same throughout. The equilibrium shape of the bays, developed from an initially straight line to the fully stable
state, was measured for various wave directions and heights. The curved portion of the shapes of the equilibrium coastline was then analyzed by fitting the log-spiral curve. A typical prototype bay in fully developed condition, derived from investigations of hydrographic charts, was then analyzed by computer to verify that diffraction and refraction combined to form the log
spiral portion of the coastline. |
