U.S.-New Zealand Cooperative Research: The Role of Spatially Complex Shoreface Roughness in Sediment Transport and Deposition: A New Zealand Case Study and Model Development

9987936 wright：该奖项支持弗吉尼亚海洋科学研究所和新西兰国家水与大气研究所之间的合作，研究空间复杂的海岸表面粗糙度在沉积物运输和沉积中的作用。该提案要求提供资金，以确定空间变化的河床粗糙度是否通过粗糙度对边界层和泥沙动力学的影响而导致泥沙通量发散的相应模式。所提供的支持将允许VIMS参与正在新西兰进行的实地和建模研究计划。参与该计划将提供一个令人兴奋的机会，收集重要的数据集，使沉积物的再悬浮和运输能够在复杂的环境中进行研究。此次合作建立在双方现有研究的基础上，并为几名美国学生提供了参加新西兰实地研究的机会。通过在新西兰的主要实地研究工作收集的额外数据将补充VIMS仪器收集的数据，并为解决这一复杂问题的研究人员提供关键数量。考虑到了解沿海环境对两国的价值，与新西兰的合作有可能在开发近岸环境预测通用模型方面取得进展，这是美国和新西兰的一个重要目标。

9987936WrightThis award supports collaboration between the Virginia Institute of Marine Science, and the National Institute of Water and Atmospheric Research, New Zealand, on the role of spatially complex shoreface roughness in sediment transport and deposition. The proposal requests funds to determine if spatially variable bed roughness causes a corresponding pattern in sediment flux divergence through the effect of roughness on boundary layer and sediment dynamics. The support provided will allow VIMS to participate in a field and modeling research program being undertaken in New Zealand. Participation in the program will provide an exciting opportunity to collect a significant data set that allows sediment resuspension and transport to be studied in a complex environment. The collaboration builds on existing research in both institutions, and provides several US students the opportunity to participate in field research in New Zealand. Additional data collected through major field research efforts in NZ will complement data collected with VIMS instruments as well as provide a critical mass of researchers addressing this complex problem.This collaborative effort with New Zealand has the potential to make progress toward developing a predictive general model for nearshore environments, an important goal for both the US and for New Zealand, given the value to both countries of understanding coastal environments.
