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莱特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在空间复杂的海面粗糙度在沉积物传输和沉积中的作用方面的合作。该提案要求提供资金，以确定空间可变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差异的相应模式。所提供的支持将使VIMS能够参与在新西兰进行的实地和模型研究计划。参与该项目将提供一个令人兴奋的机会，以收集重要的数据集，以便在复杂的环境中研究沉积物的再悬浮和迁移。这项合作建立在两所大学现有研究的基础上，并为几名美国学生提供了在新西兰参与实地研究的机会。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使用VIMS仪器收集的数据，并提供大量研究人员来解决这个复杂的问题。与新西兰的合作努力有可能在开发近岸环境预测通用模型方面取得进展，这对美国和新西兰来说都是一个重要目标，因为这对两国了解沿海环境都有价值。

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.
