Oey, L-Y., and G. L. Mellor, 1993: Subtidal variability of estuarine outflow, plume, and coastal current: A model study. Journal of Physical Oceanography, 23(1), 164-171.

Abstract: The time evolution of an estuary plume and its coastal front over a continental shelf is numerically calculated here using a three-dimensional model with eddy mixing based on the turbulence kinetic energy closure. The plume and front system is found to be unsteady with a natural period of about 5-10 days, during which the plume pulsates and intermittent coastal currents propagate down the coast.
