Abstract — The water quality near to a coral reef site in
Jebel Ali, Dubai, United Arab Emirates (UAE) was studied.
Many Physico-Chemical parameters for water samples taken at
two different depths (0.5 m and 1.0 m) parallel to a coral reef site were measured and analyzed. The data showed that the pH is equal to 6.4, 6.1 respectively which indicates an acidic
environment. The average of total dissolved solids (TDS) is
approximately equal to 43,600 mg/L and 43,200 respectively,
salinity= 46,242 µs/cm 45,880 µs/cm, specific conductance= 88,433 µs/cm and 86,566 µs/cm. The concentrations of many
other chemical parameters were studied and reported in this
article such as magnesium, copper, CaCO3, potassium, K2O.
The proportions of other inorganic species such as iron,
phosphorus, phosphorus pentaoxide, bromide, and nitrate were also studied and some of these parameters have showed low
concentrations which can indicate a desirable level of
pollutants.

The impacts of these projects have caused increased levels
of turbidity and suspended sediments carried away from the
dredge or reclamation sites5. Other possible stressors for coral reef include: coastal development, sedimentation, coral
bleaching, water pollution, destructive fishing practices, ocean acidification (due to increased atmospheric CO2), and poor
tourism practices.

The resilience of coral reefs has been eroded to an extent
that they have been unable to successfully recover as they have done before6. The article by Hughes et al. (2010) has
distinguished two types of drivers of change, slow or chronic drivers (occur concurrently and are highly interrelated) and fast drivers (occasional disturbances that change the...
