Abstract: The Ayoun Moussa thermal power plant is located on the Gulf of Suez in Egypt. The plant's two gas/oil-fired units, which generate a combined 640 MWe, use a once-through cooling water system. Water is withdrawn from an offshore open channel with earth-filled embankments and returned to the sea through two offshore buried pipes. These pipes terminate at a box-type structure discharging at the water surface through a rectangular opening in the wall of the box. The outfall is located in a shallow water depth in proximity to the Suez Canal. This raised the concern that scouring of the gulf bottom by the surface dis-charge jet could lead to sediment deposition in the canal. Another issue is the potential for warm water recirculation into the offshore channel, whose inlet is located approximately 1,500 m from the outfall. Because of the complex nature of the water source and the afore-mentioned requirements, both analytical and thermal hydraulic physical model studies were employed.
