Documenting Fine-Sediment Import and Export for Two Contrasting Mesotidal Flats

Abstract

The general goal of this project is to examine the seabed, quantitatively document the fluxes of fine sediment (over different time scales), and thereby validate localized measurements and numerical models of sediment transport. The specific objectives are to: a) document changes in bed elevation (deposition, erosion) on time scales intrinsic to the driving forces; e.g., tidal and wind-driven currents, local waves, river discharge, and interannual variability; b) measure net accumulation rates over decades at many sites to calculate fine-sediment budgets for both Willapa and Skagit tidal systems; c) examine sedimentation at sufficient locations to characterize spatial variability of grain size and its vertical stratification.
