Coastal erosion is confronting societies and the natural environment. The economic value in Australia of built assets at risk includes roads ($60 billion), commercial buildings ($81 billion) and homes ($63 billion). Hard engineering entire coastlines is rarely feasible, with beaches providing the best coastal defence along the great majority of sandy coastlines. But how wide should a buffer zone be to provide adequate protection from storms? And critically, how reliable are the present modelling tools used to predict this, and can they be improved? Underpinned by innovative field observations to fill fundamental knowledge gaps, this project aims to deliver advanced understanding and the best available solution to storm erosion prediction.

海岸侵蚀是社会和自然环境面临的问题。在澳大利亚，已建风险资产的经济价值包括公路(600亿美元)、商业建筑(810亿美元)和住宅(630亿美元)。对整个海岸线进行艰苦的工程设计几乎是不可行的，因为海滩在绝大多数沙质海岸线提供了最好的海岸防御。但是，缓冲区应该有多宽才能提供足够的风暴保护呢？最重要的是，目前用于预测这一点的建模工具有多可靠，它们是否可以改进？该项目以创新的实地观测为基础，以填补基本知识空白为基础，旨在为风暴侵蚀预测提供先进的理解和最佳可用的解决方案。
