  • Safety Based on Beach Profile Changes of Artificial Coast with Gravel Filter Layer under Irregular Waves

抄録

Safety on an artificial beach constructed based on the fail-safe concept have been studied. Beach profile changes and onshore -offshore distributions of sand particle size have been measured in the water flume. In spite of erosive waves, irregular waves might deposit sand particles on the runup area. According to increasing of the permeability of filter layers, beach profile could be equilibrium. The filter layer would promote the sorting action for sand particles, and depositional waves would deposit coarse sediments on the on shore side and fine ones on the offshore side for an erosive type beach. A filter layer has the potential to change the beach profile without water level changes. The permeability of filter layer has the more effect on velocities and water surface in the stage of run down than run up.
