Members of the Sediment Transport Modeling Lab at the Virginia Institute of Marine Science (VIMS) conduct research to improve our ability to quantify and predict sediment transport on continental shelves and in estuaries over a variety of temporal and spatial scales. We are involved in interdisciplinary projects and large experiments with field oceanographers and geologists. A recent focus has been coupling sediment transport models with ecological and geochemical models. Current research projects include efforts to:
- Coupled Ocean Modeling Testbed (COMT) Platform for Physics and Contaminant Exchange through the River - Estuary - Ocean Continuum; collaboration with Lousiana State University, Texas A&M University, and GCOOS (Gulf of Mexico Coastal Ocean Observing System). Funded by NOAA.
- Focused CoPe: Supporting Environmental Justice in Connected Coastal Communities through a Regional Approach to Collaborative Community Science; collaboration led by East Carolina University. Funded by NSF.
- Fate of Ayeryawady and ThanLien River Sediment, Myanmar: Relative Importance of Oceanographic and Tectonic Controls. Funded by NSF.
- CSOMIO: Consortium for the Simulation of Oil - Microbial Interactions in the Ocean. Funded by GoMRI (Gulf of Mexico Research Initiative).
- Shelf-slope sediment exchange in the northern Gulf of Mexico: Application of numerical models for extreme events. Funded by BOEM.
- Feedbacks between fine-grained sediment transport, biological and geochemical processes within the York River and Gulf of Mexico. Funded by NSF.
We are also active in a group of oceanographers and geologists who are working to develop a community sediment transport model by developing and testing numerical models that account for sediment transport and oceanographic circulation, and couple sediment transport to biogeochemical models.
Graduate Research Opportunities
We invite inquiries from students interested in studying sediment dispersal in coastal environments. Potential research topics include analysis of sediment redistribution offshore of rivers in Myanmar, and the impacts of resuspension on geochemistry in the Gulf of Mexico and mid-Atlantic Bight. The research will involve analysis and development of numerical models of sediment transport, written and oral communication skills, and possibly field work.
