Suspended Particulate Dynamics in Advection-Dominated Environments

Jay 0096678包括两个西海岸河口的悬浮颗粒物的声学和光学测量的大型数据集，以及广泛的辅助数据。将开发技术来将声学和光学数据转化为沉积物粒度分类光谱。然后，这些数据将与辅助环境数据相结合，以研究导致两个河口悬浮泥沙分布的过程，特别是河口最大浑浊度的发展和变化，这是一个悬浮泥沙浓度增加的区域。最后，建立了河口最大浑浊度动力学的综合理论，并与前人的分析结果进行了比较。一般而言，河口悬沙输运，特别是最大浑浊度的动态，对于河口污染物输运、航行和海洋生物资源的管理是重要的。建议的分析和综合将集中于我们对这些过程在广泛的河口类别中的概念性理解。

Jay 0096678A large data set consisting of acoustic and optical measurements of suspended particulate matter is available from two west coast estuaries, as well as extensive ancillary data. Techniques will be developed to invert the acoustic and optical data to sediment size class spectra. These will then be combined with the ancillary environmental data to study the processes responsible for the distribution of suspended sediment in the two estuaries and, in particular, the development and variability of the estuarine turbidity maximum, a region of enhanced suspended sediment concentration. Finally, a comprehensive theory of the dynamics of estuarine turbidity maxima will be developed and compared to the results of the previous analyses. Estuarine suspended sediment transport, in general, and the dynamics of the turbidity maximum, in particular, are important for the management of pollutant transport, navigation, and living marine resources in estuaries. The analyses and syntheses proposed will focus our conceptual understanding of these processes in a broad class of estuaries.
