 | The goal of our Tidal Flats research is to expand our understanding of the erosional and depositional processes that lead to exchange of mud between tidal channels and tidal flats. We also investigate the effect of sediment texture on sediment strength. Our research on Tidal Flats DRI had three primary objectives: 1. Improve understanding of how turbulence and sediment concentration affect the size-dependent depositional flux of sediment to the seabed ... |

Achieving these goals will improve the skill of sediment transport models and hence prediction of underwater visibility. Objectives: 1. Quantify the effects of aggregation dynamics on the size distribution of particles in the ... |

OBJECTIVES: The rate of muddy sediment erosion is very difficult to predict, yet it is crucial to know in predicting the evolution of mud flats as a result of natural or anthropogenic perturbations. Our objective is ... |

| The long-term goals of this research are to develop and test a particle aggregation parameterization in turbid, river, discharge plumes. The proposed research has two objectives. The first is to monitor the evolution of in situ and disaggregated particle size distributions in the Eel River plume during major discharge events.

|
| The long-term goal of this research is to develop tools to quantitatively predict the effect of fine siliciclastics on water clarity in the coastal ocean. Scattering of light by suspended particles depends on sediment concentration, composition, and size distribution. Particle size distributions in coastal waters are dynamic because high concentrations of suspended sediment in coastal waters favor frequent encounter between particles. These encounters lead to the formation of large macroaggregate ... |
