DTIC ADA514899: Erodibility of Mud: Characterization and Prediction

The long terms goals of this study 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. Specific objectives of this study are to: 1) Measure temporal variation in consolidation and erodibility of mud and mud/sand mixtures under controlled laboratory conditions; 2) Compare measured erosion parameters with values of shear strength made with a small cone penetrometer (focusing on the near-surface layer of the bed); 3) Use the results to improve formulations for mud deposition, consolidation, resuspension and net erosion in shelf sediment transport models.
