Through a series of controlled laboratory experiments and numerical model development, this project aims to determine and quantify for the first time the role of water infiltration on sandy soil stability at actively eroding coastal sand dunes. This project expects to generate much-needed understanding of fundamental dune erosion processes using innovative instrumentation to obtain continuous measurements of wave-dune interactions, dune profile evolution, and water infiltration. Expected outcomes of this project include improved coastal engineering models to predict dune erosion under waves and increasing water levels. This should provide significant benefit to the future management of coastal assets using nature-based solutions.

通过一系列受控实验室实验和数值模型开发，该项目旨在首次确定和量化水渗透对积极侵蚀的沿海沙丘的桑迪土壤稳定性的作用。该项目预计将产生急需的基本沙丘侵蚀过程的理解，使用创新的仪器，以获得连续测量波沙丘相互作用，沙丘剖面演变和水渗透。 该项目的预期成果包括改进沿海工程模型，以预测波浪和水位上升对沙丘的侵蚀。这将为今后使用基于自然的解决方案管理沿海资产带来重大益处。
