摘要

Seawater desalination has become the only viable source of fresh water for Kuwait.However,desalination plants could have several impacts on the surrounding marine environment.The major concern of these impacts surrounds the outfall effluent discharge because of its physical and chemical features including high temperature and salinity associated with residual chemicals used in the pretreatment process.In this study assessment of potential impact of Az-Zour desalination plant discharge effluent on marine environment was carried out.The assessment consisted of field measurements and numerical modelling of effluent dispersion.The results revealed a potential impact by temperature and salinity between 4 and 6 oC and 2-4 ppt above ambient and mean levels for Kuwait seawater.The predictions of hydrodynamic modelling show that the plume from the outfall runs parallel to the shoreline and the influenced area can reach to about 40 km^2.
