"The Dynamics of Flow Over Ripples and Dunes"

本文研究了有限深度水流下活动河床表面波纹和沙丘的动力学。在水力水槽中的理论建模和实验将被用来促进对水流和床面结构之间相互作用的理解。二维和三维构型都将被研究。研究结果有望提高预测河流和渠道侵蚀、输沙和底部地形的方法的可靠性和准确性。

This research deals with the dynamics of ripples and dunes on the surface of a movable bed beneath water flow of finite depth. Theoretical modeling and experiments in a hydraulic flume will be used to advance the understanding of the interaction between flow and bed surface configuration. Both two-dimensional and three- dimensional configurations will be investigated. Results are expected to advance the reliability and accuracy of methods for predicting erosion, sediment transport, and bottom topography of rivers and channels.
