Transportation of Water Spray on Non-Wave Overtopping Type Seawall

摘要

Authors have proposed a non-wave overtopping type seawall with adeep circular cross section, named as Flaring Shaped Seawall; FSS. Ithas already confirmed that the FSS satisfies a non-wave overtoppingcondition with an extremely lower crest height in comparison with aconventional upright seawall. Besides this advantage, a reduction ofthe water spray transportation behind the seawall is also required inorder to facilitate a safe and excellent use of coastal space. In thisstudy, the characteristics of spray transport on FSS are investigated.Furthermore, a technical device to reduce the quantity of spray on FSSis proposed, and its performance is also confirmed.
