COMPUTATION OF THE RESIDUAL FLOW IN THE GULF USING THE MT MITCHELL DATA AND THE KFUPM RI HYDRODYNAMICAL MODELS/

The hydrodynamical models of the Gulf developed at KFUPM Research Inst itute are briefly described. The models are used to compute the flows in the Gulf driven by density gradient using the two sets of data coll ected on Legs 1 and 6 of the Mt Mitchell cruise. The two flows are com pared with one another, with the result of a similar computation using the 1977 Atlantis II data and with computations of the flow driven by the prevailing wind. The combined residual flow due to wind and densi ty gradient is found and compared to empirical estimates of the residu al flow derived from ship-drift reports. The accuracy of the models is tested using the computed and observed water velocities at some of th e current meters deployed during the cruise.
