QuestionAnswer
what are the two types of coastal protection structures hard and soft
what are hard structures prevent erosion and are usually large and made from resistant rock or reinforced concrete
what are sea walls they are made from reinforced concrete and are curved to deflect the breaking wave back onto the incoming wave eg. Lahinch
what are gabions steel mesh cages fillled with stones. They reduce the energy of incoming waves as they waves energy is spread out, reducing its energy
what are goynes low walls made from wood or cement built perpendicular to the shore. They trap sediment being moved along the coat by longshore drift. This allows material to accumulate and prevents erosion of beaches eg. youghal beach
what is rock armour large boulders are placed along a coastline to reduce sea erosion, as when a wave hits against them it reduces their energy
what are soft structures they are not permanent and they repair damage caused by destructive waves
what is beach nourishment adding new sand to beaches by dredging sand from offshore eg rosslare
what is sand dune repair marram grass is planted as the roots bind sand together making it more resistant
