The Dynamics of River Plumes: the Relationship between Inflow Conditions and Alongshore Transport

0118029 PI假设河口的河流羽流条件控制滞流点的撞击角度，然后控制流入下游沿岸流的水的分裂和与流出羽流相关的凸起。提出了实验室实验和数值模拟相结合的方法。需要回答的问题包括：河流羽流天生就依赖于时间吗？河口参数如何影响近岸和跨岸运输？沿岸流中地转平衡的假设是否一致有效？这些研究将确定氦羽流、滞流点和沿岸流的结构，并描述沿岸流内的传输场。五种实验室情况包括标准的低入射角、高罗斯比数、高弗劳德数和非零底坡情况。实验室运行的重复性允许将来自多个运行的数据(至少是前7-10个轮次)组合在一起进行分析。

0118029MonismithThe PI hypothesizes that river plume conditions at the river mouth control the angle of impact at the stagnation point, which then controls the split of waters that flow into the downstream coastal current and the bulge associated with the outflow plume. Laboratory experiments, complemented by numerical modeling, is proposed. Questions to be answered include: Are river plumes inherently time dependent? How do river mouth parameters affect alongshore and cross-shore transport? Is the assumption of a geostrophic balance in the coastal current uniformly valid? The studies will define the structure of he plume, the stagnation point, and the coastal current, and describe the transport field within the coastal current. Five lab cases include a standard, low inflow angle, high Rossby number, high Froude number, and non-zero bottom slope situations. Reproducibility of the lab runs allows data from multiple runs (at least for the first 7-10 rotations) to be combined for analysis.
