项目摘要
The team of S. Burges and P. De Vries (Univ. of Washington) and G. Parker (Univ. of Minnesota) plan collaborative research into the mechanics of coarse bedload transport at the particle scale. Gravel tracer particles are a convenient way to study the longitudinal travel and dispersion and vertical mixing of sediment in mountain rivers. Field observations of tracer displacement have not yet, however, been linked comprehensively into the formal framework of sediment transport in rivers.The study will use experiments as a bridge between theoretical/numerical research and field-scale research to a) develop formulations for distance moved, dispersion and mixing of tracers for unsteady flow, b) link these formulations to mechanistic theories of bedload transport and c) test and validate the results against field data taken to the standards needed to test theory and numerical predictions.The field research will be conducted in several streams in western Washington State. The experimental research will be conducted at St. Anthony Falls Laboratory. The Washington and Minnesota teams will collaborate on both efforts, with both sides contributing to the development of a predictive numerical model.
团队的S。布尔日和弗里斯(华盛顿大学)和G.帕克(明尼苏达大学)计划在颗粒尺度上对粗泥沙输运力学进行合作研究。 砾石示踪颗粒是研究山区河流泥沙纵向运移、扩散和垂向混合的一种简便方法。 然而,示踪剂位移的现场观测尚未全面地与河流泥沙输移的正式框架相联系,本研究将利用实验作为理论/数值研究与现场规模研究之间的桥梁,以a)开发非恒定流示踪剂移动距离、分散和混合的公式,B)将这些公式与推移质输运的机械理论联系起来,以及c)根据测试理论和数值预测所需的现场数据,对结果进行测试和验证。现场研究将分几个流进行在华盛顿州西部。 实验研究将在圣安东尼福尔斯实验室进行。 华盛顿和明尼苏达州的团队将在这两方面开展合作,双方都将为预测数值模型的开发做出贡献。
