Coastal Processes and Landforms Coastal Processes and Landforms
Wave refraction and longshore current• As waves reach the shore they “feel” the bottom, slow and break• The direction of eave break follows the underwater topography• Causes wave to “bend” and become more parallel to shoreline – bending called waverefraction• As it breaks from one side to the other, it creates a current called the longshore current
