Sediment Transport at Density Fronts in Shallow Water

Abstract

LONG-TERM GOALS: The goal of the overall research was to quantify through observations and modeling how density fronts in shallow estuarine flows impact the mobilization, redistribution, trapping, and deposition of suspended sediment. This current award was a continuation of the original YIP award in order to deliver a remaining increment of funds that had not been allocated. The focus of this continuation was to examine how stratification on the tidal flats varies in parameter space as a function of dimensionless numbers. OBJECTIVES: The objectives of this continuation award were to * analyze results from a high-resolution, 3-dimensional, finite-volume hydrodynamic model of the Skagit tidal flats to examine processes leading to the creation and destruction of stratification, * use the Simpson number to represent the balance between tidal straining and tidal mixing to place the physical processes on the tidal flats in a more general context of estuarine and coastal stratification dynamics
