Cohesive and mixed sediment in the Regional Ocean Modeling System (ROMS)
[[Image:|300px|right|link=File:]]We have implemented algorithms for treating fine and cohesive sediment that are in the Regional Ocean Modeling System (ROMS). These include: floc dynamics (aggregation and disaggregation in the water column); changes in floc characteristics in the seabed; erosion and deposition of cohesive and mixed (cohesive and non-cohesive) sediment; and biodiffusive mixing of bed sediment. These routines supplement non-cohesive sediment routines, thereby increasing the model ability to represent fine-grained environments where aggregation, disaggregation, and consolidation may be important. Additionally, we describe changes to the sediment bed layering scheme that improved the fidelity of the modeled stratigraphic record. This poster provides examples of these modules implemented in idealized test cases and a real-world application.
