Cross-Shore Sand Transport on Beaches

该项目将利用实验室和数值模型来开发一个沉积物迁移模型，该模型可以预测海滩上的岸上和海上泥沙迁移。 没有任何现有的模型可以解释风暴后海滩的恢复，因此不可能预测风暴造成的海滩侵蚀和恢复的长期周期。 波浪水槽将用来模拟不规则波浪对平衡海滩的影响，并将根据平衡值估计珠载输运。 然后，第二组实验将评估非平衡条件下的效应，以评估模型的性能。

This project will use laboratory and numerical modelling to develop a sediment transport model that can predict both onshore and offshore transport of sand on beaches. No existing model can explain post-storm recovery of beaches and therefore it is not possible to predict the long-term cycle of beach erosion and recovery resulting from storms. A wave tank will be used to simulate the effects of irregular waves upon equilibrium beaches, and beadload transport will be estimated from the equilibrium vales. A second set of experiments will then assess effects under non-equilibrium conditions, to evaluate performance of the model.
