Bringing granular mechanics to prevent fluid-driven soil erosion problems

该项目旨在通过探索不断演变的地形和陆上水流之间的相互作用来研究土壤的侵蚀行为。它希望通过创新的高速X射线成像和详细的数值模拟，在不同的流动条件下产生关于主要颗粒机制的新知识。预期的结果包括一个简单的数学框架，该框架考虑了这些重要因素，它将连接地质力学和流体力学，提供对长期侵蚀和沉积速率的宝贵见解。这将提高我们的预测能力，从而防止严重的土壤流失或有问题的泥沙堆积，从而提供显著的好处。

This project aims to investigate the erosive behaviour of soils by exploring the interaction between evolving topography and overland water flow. It expects to generate new knowledge about the dominant granular mechanisms under different flow conditions using innovative high-speed X-ray imaging and detailed numerical simulations. Anticipated outcomes include a simple mathematical framework that takes these important factors into account, which will bridge geomechanics and fluid mechanics to provide valuable insight into long-term erosion and deposition rates. This should provide significant benefit by enhancing our ability to predict, and therefore prevent, intense soil loss or problematic build-up of sediment.
