“…The model used is an adaptation of the one described by Johns et al (1991). The governing equations are obtained by considering the conservation of mass, momentum, temperature and salinity, and by using the Boussinesq approximation and the hydrostatic equilibrium.…”

The plume of the Rhone (western Mediterranean) is studied with the help of a three-dimensional ocean model using primitive equations. Particular attention is paid to the wind forcing. Three simulations of realistic cases, using wind and river discharge measurements, are described. Satellite observations of the plume make it possible to assess the quality of the numerical simulation in each case. The analysis of circulation enables an evaluation of the characteristic time scales of deformations in the plume during changes in wind conditions and also highlights the high sensitivity of the plume to the surrounding circulation, dominated by coastal currents associated with upwelling and downwelling motions induced by the northwest and southeast winds .

“…The multi-level breath averaged models developed for this purpose involve the parameterization of Reynold's stresses. Parameterization of eddy diffusivity has been carried out either by using simply the first order closure schemes [1,4], a one equation model using algebraic mixing length [6,7], or by higher order turbulence closure schemes using prognostic equations for mixing length and turbulence energy for the three-dimensional models [2,13]. Studies on the inter-comparison of a range of turbulence models have been done for shelf regions [3,19].…”

SUMMARYA three-dimensional numerical model has been applied to study the impact of freshwater discharge from a river on the coastal circulation in the western Bay of Bengal. The basic dynamical framework of the model follows closely that described by Johns et al.' for the simulation of coastal upwelling off the east coast of India. Using this model, experiments have been performed to investigate the impact of the freshwater discharge at the location of Godavari river along the east coast of India. A comparison of the model results, with and without the inclusion of river discharge, shows that the river discharge into the western Bay of Bengal suppresses the upwelling near the river mouth. Though there are no detailed observations on the flow structure near the mouth of the Godavari river, the computed results are in qualitative agreement with the observations documented by Rao and Jayaraman2 and R~o ,~ who have shown that during monsoon period the upwelling off Godavari estuary is suppressed.
