Wave Simulation with Different Type of Coast Protection Structure - A Comparative Approach

Abstract: Coastal zones, and more precisely, the shoreline is constantly changing due to the action of waves, tides and human impact. The anthropic pressure on the coastal zone is growing more and more and implies the intense development of human activities as close as possible to the shoreline. This has led to the implementation of coastal protection measures, the hydro-technical structures, to prevent further damage to the shoreline, the coastal erosion. This is an important problem facing coastal zones around the world and requiring the implementation of coastal protection systems to prevent further damage to the shore. Coastal erosion occurs as an effect on sediment transport, modifying shore morphology. The sediments in the coastal zone are the moving element of seashore being moved by the action of the waves and currents on the transverse and longitudinal direction to the shoreline. In this paper we will present the changes that occurs on the waves after the impact with a protection structure or more and the changes that occurs in the shoreline.
