Synopsis :
OCE614 offered in the Spring, addresses coastal modeling problems, i.e.,
the solution of coastal problems involving water waves, currents and sediment
transport, using computer models. Fundamentals of the theories and methods
used for developing computer models are covered, and actual computer models
are used for illustration, and for homework assignments.
