· Marine erosional processes Hydraulic action Air is trapped in the joints and cracks of a cliff by a wave This exerts pressure on the rock wall As the wave retreats the pressure is released with a sudden jolt causing parts of rock to break off Corrosion Parts of a cliff are eroded by the acid of the sea water which dissolves
Longshore sand transport is the process that moves sand parallel along a beach or coastline On long open beaches such as at the Tweed and Gold Coast this process moves sand predominantly from the south to north pushed by the prevailing south easterly crashing waves push the sand onto the beach; sand is then dragged offshore in the swash zone before being pushed back onto the
sand handling processes By adding a secondary sand reclamation process foundries can expect to become more energy efficient as well as reducing solid waste from the foundry To measure the broader environmental impacts life cycle assessment LCA can be used The goal of the current research was to examine a medium sized foundry in the United States that sources its sand from a long
