Shoreline progradation in Poverty Bay, New Zealand
We are studying sediment redistribution within Poverty Bay,
New Zealand, offshore of the Waipaoa River. Funded by the NSF Margins Source to Sink
, this study involves field observations of sediment flux and
seabed properties. The focus of our group is to develop a three-dimensional numerical model of hydrodynamics and
sediment transport for Poverty Bay, and to link our
high-resolution simulations to models of stratigraphic
Funded by the NSF
CBED program, MUDBED
(MUltidisciplinaryBenthic Exchange Dynamics) is examining
how interactions between biological and physical processes impact fine-grained
sediment resuspension. My part in the effort involves developing a
three-dimensional sediment transport model for the field site, the York River estuary. Planned improvements to the
three-dimensional model include better treatment of bed consolidation and
Funded by the NOAA, the Northern Gulf of Mexico Ecosystem Research
(NGOMEX) study is examining how physical, geochemical, and
processes impact hypoxia in the Gulf of Mexico. Our lab is focusing on efforts to develop a
three-dimensional sediment transport model for the Texas/Louisiana coast
and interfacing the sediment calculations with a biogeochemical model.
Funded by the Office of Naval Research, the EuroSTRATAFORM
program hopes to improve our ability to relate water column transport processes
to the resulting morphology of the seabed. Work at VIMS included implementation
of a sediment transport routine within ROMS, a three-dimensional hydrodynamic
model. ROMS has been used at VIMS to
evaluate which processes lead to sediment dispersal and deposition within the Adriatic Sea.
New York Bight
Funded by the U.S. Geological Survey's Pollution Program, this project has worked
to quantify sediment transport and flow patterns in the New York Bight offshore
of New York and New Jersey. Especially interesting are sedimentation and
flow patterns in the vicinity of the Hudson Shelf Valley—the drowned axis of the paleo-Hudson River. The field observations and modeling program have led to publications that
