U.S.-U.K. Cooperative Research: Integration of Mathematical Modeling, Physical Modeling and Field Research for Advanced Understanding of River Dynamics

这个为期三年的地理和区域科学合作研究奖涉及美国和英国的团队。布鲁斯·L·罗兹、马塞洛·H·加西亚、丽贝卡·韦德和他们在伊利诺伊大学的研究生组成的美国团队提议与利兹大学的斯图尔特·莱恩、詹姆斯·贝斯特、菲利普·阿什沃斯、谢菲尔德大学的罗伯特·弗格森和剑桥大学的基思·理查兹以及这些机构的研究生合作。美国和英国的团队将探索天然河流中时间平均的流体运动和湍流的三维结构，开发并经验性地测试具有泥沙输送和岸坡侵蚀功能的河道动力学数值模型。河流和河流是地球表面侵蚀和沉积变化的媒介。尽管对河流的形态和过程进行了大量的研究，但在理论上需要对河流在时间和空间上的行为进行定量预测。拟议的跨学科合作通过研究和开发经过实地测试的预测模型来解决这一问题。美国和英国的研究团队是计算流体力学方面的专家，并为这次合作带来了不同的方法、来自各自实验室的模型模拟的详细测量以及计算建模和现场测试方面的专业知识。

0097059RhoadsThis three-year award for cooperative research in geography and regional sciences involves teams in the United States and in the United Kingdom. The US team of Bruce L. Rhoads, Marcelo H. Garcia, Rebecca Wade and their graduate students at the University of Illinois propose to collaborate with Stuart Lane, James Best, Philip Ashworth at the University of Leeds, Robert Ferguson at University of Sheffield, and Keith Richards at Cambridge University along with graduate students from these institutions. The US and UK teams will explore the three-dimensional structure of time-averaged fluid motion and turbulence in natural rivers and develop and empirically test numerical models of river-channel dynamics with functions for sediment transport and bank erosion.Streams and rivers are agents of erosion and depositional change on the Earth's terrestrial surfaces. Despite enormous amounts of research on fluvial forms and processes, there is a theoretical need for predicting quantitatively the behavior of river channels over time and space. The proposed interdisciplinary collaboration addresses this problem through research on and development of a field-tested predictive model. The US and UK research teams are expert on computational fluid dynamics and bring to this collaboration different approaches, detailed measurements of model simulations from their respective laboratories, and expertise in computational modeling and field testing.
