COASTAL EROSION - Know More

Coastal Erosion Erosion processes operating at the coast Wave Pounding Steep waves have high energy levelThese waves break when they hit sea walls of the foot of a cliff, hence their energy is released upon impact, resulting to shock waves of up to 30 tonnes per m 2This constant bombardment is so destructive that sea walls in the UK need replacing every 25 years...
