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

拟议的研究将检查新西兰Waipaoa河陆架上不同河流流量和海洋条件下的沉积物输运和沉积，并结合在美国西海岸边缘沿着的其他河陆架站点所做的工作，建立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流的运输和沉积模式，陆架系统。目标是调查在河流陆架系统上形成可淹没的洪水和风暴床的条件，并建立一个概念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响应采样，水动力学和沉积动力学的实验数值模拟，以及对大陆架系统沉积物迁移期间的河流和海洋状况进行全球范围的统计分析。更广泛的影响包括一个新的，年轻的女博士后研究员的支持和本科生和研究生的参与。研究结果可供从事海岸研究和政策问题的广大工作者参考。

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.
