MARGINS Post-Doctoral Fellowship: Investigating sediment dynamics on the Waipaoa River shelf, New Zealand: creating a framework to predict preservation on continental margins.

这项拟议的研究将研究新西兰怀保阿河陆架在不同河流流量和海洋条件下的泥沙输运和沉积，并与美国西海岸边缘其他河架地点的工作相结合，创建一个框架来解释这些河流系统之间的差异和相似之处，并评估尚未研究的河架系统的输运和沉积模式。目标是调查河架系统形成可保存的洪水和暴雨床的条件，并建立一个概念性框架来预测边缘洪水和风暴床的保存潜力。这项研究将需要快速反应采样，水动力学和沉积物动力学的实验性数值模拟，以及对陆架系统沉积物输送过程中的河流和海洋条件的全球范围的统计分析。更广泛的影响包括支持新的年轻女性博士后研究人员，以及本科生和研究生的参与。研究结果可能对广泛关注沿海研究和政策问题的工作人员有所帮助。

The proposed research will examine sediment transport and deposition under varying fluvial discharge and oceanic conditions on the Waipaoa River shelf, New Zealand, and combined with work done at other river-shelf sites along the US West coast margin, create a framework to explain the differences and similarities amongst these river systems and assess transport and depositional patterns on as yet unexamined river-shelf systems.Objectives are to investigate the conditions under which preservable flood and storm beds form on the river shelf systems and to create a conceptual framework to predict preservation potential of flood and storm beds on margins.The study will entail rapid response sampling, experimental numerical modeling of hydrodynamics and sediment dynamics, and a global-scoped statistical analysis of the fluvial and oceanic conditions during sediment transport on shelf systems. Broader Impact include the support of a new, young female post-doctoral researcher and involvement of undergraduate and graduate students. The results could be useful to wide range of workers concerned with the coastal research and policy issues.
