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.

通过一系列受控的实验室实验和数值模型的开发，该项目旨在首次确定和量化水在积极侵蚀沿海沙丘上的水对沙质土壤稳定性的作用。该项目希望使用创新仪器对基本的沙丘侵蚀过程产生急需的理解，以获得对波浪-nune相互作用，沙丘剖面演变和水渗透的连续测量。 该项目的预期结果包括改进的沿海工程模型，以预测波浪下的沙丘侵蚀并增加了水位。这应该使用基于自然的解决方案为未来的沿海资产管理提供重大好处。
