Sediment Flux and Trapping on the Skagit Tidal Flats

Abstract

The objectives of our 2008-2009 research program are: to quantify the influence of barotropic (tidal) convergence on the lower Skagit tidal flats as a mechanism of sediment trapping and creation of ephemeral mud and sand deposits; to determine the role of density fronts in creating and transporting high-concentration sediment suspensions, and assess the influence of these processes on sediment deposition and short-term morphological change; to distinguish the influence of wave-induced sediment transport from tidal/fluvial processes, and determine how variations in tidal, fluvial and wind/wave forcing alter the bedform geometry, transport pathways, surficial sediment characteristics and tide flat morphology.
