Teaching and Research
Professor Foda teaches an undergraduate course in elementary fluid mechanics
and a graduate course in physical oceanography with an emphasis on the
dynamics of continental shelf waters. He also teaches a graduate course
in coastal engineering that covers topics on nearshore processes, shoreline
evolution, and coastal structures. His research focuses on sea bed and
porous media dynamics in general. Recent research involves theoretical
and experimental work on the stability of marine pipes as they interact
with water waves and the porous, erodible sea bed. Other topics include
the fundamental problem of the interaction of water waves with deformable
sandy and muddy beds. Of particular interest are the fluidization processes
induced by wave motion near the mudline. Wave propagation through fluid-filled
porous media is another problem of current interest, with the objective
being to examine the various processes of fluid-solid interaction that
may lead to the spectacular phenomenon of soil liquefaction.
Seabed mechanics
Here we study the nature of energy transfer across the mudline, from
propagating ocean waves to upper-stratum marine sediments. Previous linear
interaction models have failed to describe the spectacular energy transfer
that sometimes takes place under storm wave conditions. We have shown that
nonlinear dynamics are responsible for this transfer of energy to the seabed.
This research, which was the first to consider nonlinearity in the problem
of fluid flow above a compliant bed, has highlighted the significant effects
of nonlinear dynamics in the sea-seabed interaction problem.
