Résumé partiel
Seawater desalination is a reliable solution to the water shortages in the arid Middle East and North Africa countries. Due to prolonged drought conditions, and a rapid economic development with sharp growth of the population in the industrial coastal areas, limited underground water resources are being used faster than they can be replenished. For Oman, in particular, with the availability of desalination water, it is envisaged that groundwater abstracted from the wells be reduced, and it will also eventually resolve the critical problem of seawater intrusion into the coastal aquifer. However current desalination technology limits the efficiency of producing desalinated water, and up to 60% is lost via unwanted brine product, a concentrate stream (typically double seawater salinity) that must be continuously discharged back to the sea. Model simulations for the mixing and spreading of desalination brine discharged through outfalls into the sea from coastal seawater desalination plants will be carried out in two parts : i. in the far field region, where the brine effluent plumes are eventually dispersed in the ambient environment, analytical solutions for a two-dimensional advection-diffusion equation with a point source are obtained and used to investigate the long time effects of brine discharges in a tidally oscillating flow, an ii. ii. in the near field region, where the initial momentum of discharge and brine buoyancy dominate, commercial PC-based software packages CORMIX and VISJET are used to simulate and graphically visualize the evolution of three-dimensional effluents plume released from marine outfalls into the sea
