    Abstract

    This study set out to assess the benefits of a soft engineering approach to sea defence, the study will be conducted by visiting a soft engineering site at Pevensey Bay where a beach recharge scheme is used, and a hard engineering site at Chesil Beach using sea walls, gabions and revetments, and looking at the various impacts and benefits that the schemes have had socially, economically and environmentally, as well as show sustainable the schemes are. Then by looking at the benefits that the defence schemes hae had and how sustainable they are comparisons can be drawn. The study is being conducted to promote the awareness of the soft engineering sea defence options and the benefits that they bring, especially from an environmental aspect.
    the study found that both schemes had been very successful and that storm events had occurred at Chesil Beach and had successfully been defended against. The schemes had brought in vast economic development to the areas respectively and had boosted the local economies. However it was found in the long term that the more sustainable option was the soft engineering scheme and that the way that the scheme was managed gave it many advantages. It was also shown that the hard scheme had had a large visual impact upon the coastline, whereas the soft scheme was simply restoring the existing landscape.
