This program is twofold. First, geographical and historical data from within watersheds will be compared with accurately dated sediments (varves) to look at the global dynamics and causes of hypoxia, eutrophication, soil erosion, carbon fluxes, or flood events during the Anthropocene and to reveal regional differences. Second, physical models of rivers, lakes and beaches will be analysed by setting an hydraulic flume within a CT-Scanner in order to characterize the bedload, a poorly understood but important component of the fundamental equations of sediment dynamics. Modeling the formation and preservation of varved sediments makes the link between these two parts.

这个计划是双重的。首先，流域内的地理和历史数据将与准确年代的沉积物（varve）进行比较，以研究人类世期间缺氧、富营养化、土壤侵蚀、碳通量或洪水事件的全球动态和原因，并揭示区域差异。其次，将通过在 CT 扫描仪内设置水力槽来分析河流、湖泊和海滩的物理模型，以表征床载量，这是沉积物动力学基本方程的一个鲜为人知但重要的组成部分。对泥沙沉积物的形成和保存进行建模将这两部分联系起来。
