This thesis aims to investigate the fate and transport of the effluents discharged from
The desalination plant as well other facilities located in the Ruwais Industrial Complex
(RIC) in the United Arab Emirates. These effluents are discharged in to the Ruwais
Coastal marine waters. The effluents from the desalination plant are characterized by
warm water with high salinity, whereas one other effluent is characterized by high n
Nutrient loads. The characterization of the Ruwais environment and such effluents are
Addressed through comprehensive field surveys of the Ruwais costal water over one
In order to investigate the impacts of such effluents on the coastal marine
Water quality, a coupled physical- biochemical model is employed to study the
hydrodynamics an d the water quality of the Ruwais coastal water. Hydrodynamic
simulation for the entire basin of the Arabian Gulf is developed as regional model,
an d the mean currents an d the circulation phenomenon in the Gulf is described.
Subsequently, a local model for the Ruwais coastal water is nested inside the regional
Model area with three open boundaries across the Gulf basin, to investigate the mean
Currents of the coastal area in addition to the spatial an d temporal variation of
Temperature and salinity.
To investigate the quality of the Ruwais coastal waters, the water quality model “EUTROP" is used. This model takes into consideration several water quality compartments, i.e., phytoplankton, zooplankton, particulate organic matter, dissolved organic carbon , phosphate, ammonium, nitrite, nitrate, dissolved oxygen , and chemical oxygen demand. The investigation of water quality covers up to 4 future years an d employs two different boundary conditions. The study evaluates the present conditions and the future conditions, where the expansion of existing facilities in the Ruwais area is considered.
It is found that the effects of the effluents in the currents conditions is limited an d
Restricted to the outfall area. It is characterized by slight increase in the temperature and salinity without major problems related to the water quality. Moreover, the influence of the future expansion in connection with increase in temperature and salinity extends up to 10 Km offshore without major impacts related to water quality beyond that limit.
