abstractcts - 0096916 g。PI建议开发一个数值模型，以准确预测低坡度沙床河流下游沉积物的细化。这一现象对了解河流动态、长期景观演变和河道变化具有重要意义。该模型将解释泥沙输运过程中发生的关键物理机制。在明尼苏达大学和特温特大学获得的实验室实验结果将用于验证泥沙输送模型。总体结果将与从巴布亚新几内亚和阿根廷河流获得的实地试验数据进行比较。
英文摘要
AbstractCTS-0096916G. Parker, University of MinnesotaThe PI proposes to develop a numerical model to accurately predict the downstream fining of sediment in low gradient, sand-bed rivers. This phenomenon is very important in the understanding of river dynamics, long-term landscape evolution, and channel alteration. This model will account for key physical mechanisms occurring in the sediment transport process. Laboratory experimental results obtained at the University of Minnesota and at the Twente University will be used to validate the sediment transport models. Overall results will be compared to field test data obtained from rivers in Papua New Guinea and Argentina.
