Hydrodynamie modelling of water circulation in the Red Sea basin Y. R. Fares Centre for Environmental Health Engineering, Department of Civil Engineering, University of Surrey, Guildford GU2 5XH, UK EMail: Y.Fares@surrey.ac.uk Abstract The effects of seasonal changes of wind stress and thermo-haline fields on the circulation of water masses in the Red Sea basin are reported. A generalised formulation for such a complex circulation system is proposed. The model consists of a multi-layer structure; a surface layer (shallow and mixed) superimposed by a series of relatively deep layers of isothermal and isohaline nature. The effects of latitude variations along the basin north-south extent are simulated by a variable Coriolis parameter. In addition to the effects of bottom topography and coastal configuration, the flow exchange between the Red Sea and the Gulf of Aden at its southern exit are included. The turbulent friction stresses are modelled by a non-linear mass transport dependenc
