Cohesive and mixed sediment in the Regional Ocean Modeling System (ROMS)

Chris Sherwood, USGS Woods Hole Massachusetts, United States. 384 Woods Hole Road



[[Image:|300px|right|link=File:]]We have implemented algorithms for simulating fine and cohesive sediment 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 existing non-cohesive sediment routines in ROMS, 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 improve the fidelity of the modeled stratigraphic record. This poster provides examples of these modules implemented in idealized test cases and a real-world application.
