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.
