Abstract:

The long-term goals are to explain the evolution, dynamics, and morphology of bedforms found in sandy inner-shelf environments, using laboratory and field observations and numerical modeling. Our objective is to analyze existing laboratory data including measured suspended sediment profiles and ripple wavelengths during ripple evolution, and observations of bedform migration, and to use the results to support calibration of a Large Eddy Simulation of ripple evolution under development by Fringer and Chou at Stanford University. Specifically, we aim to Analyze the relationship between time-averaged suspended sediment profiles and bedform dimensions, wave energy, and current speed Compare results to existing analytical models, and develop new parameterization of these relationships if merited Analyze bedform migration and bedload transport from flume experiment sonar data, and relate to flow conditions and Provide data sets and analytical results to Fringer and Chou for model testing.
