Longshore drift is a geological process that involves transporting sediments such as single and pebbles along a coast parallel to the shoreline. It is dependent on the angle of the incoming wave direction. Incoming wind squeezes water along the coast, which generates a water current which moves parallel to the coast. Longshore drift is the sediment moved by this longshore current. This current and sediment movement occurs within the surf zone. 

Longshore drift has happened along Meon Shore over the years I have watched the shoreline change with shingle spits changing and growing and the beach make-up changes as the shingle size changes. Wooden groins slow the currents and help stop erosion. The small harbour at Titchfield Haven entrance gets blocked up as stones and sand get dropped in that area as the currents slow and can not hold their weight as they slow. This week the sailing club has been moving the shingle back from the harbour mount to fill in the area on the spit that is being eroded with it.

A day out is not complete without some nature watching.
