Erodibility of Mud: Characterization and Prediction

Abstract

The long-term goal is to improve our capabilities for measuring and predicting erosion rates, sediment flux, water clarity and bed strength in muddy coastal environments, particularly with respect to their evolution through time on tidal flats. The objectives of my current work within the Tidal Flats DRI are: 1) Measure temporal variations in erodibility and shear strength of tidal flat and channel sediment in Willapa Bay. 2) Measure temporal variation in consolidation and erodibility of sediment from Willapa Bayunder controlled laboratory conditions; 3) Correlate temporal and spatial variations in erodibility with other sediment, channel and flow characteristics. 4) Use the results to improve formulations for mud deposition, consolidation, resuspension and net erosion in shelf sediment transport models.
