Abstract
Aim: The projected dredging of the Musa Bay apart from its economic potentials was hinged on the following factors: Eutrophication, sedimentation and pollutants. This investigation surveyed the following parameters for surface samples: DO, pH, Conductivity, TDS, Nitrate, Phosphate, BOD, COD and Salinity.Methods: This study 9 points as sampling stations were chosen in Imam Khomeini Port (49˚05ˊ ;30˚25ˊ) that 3 replicates of each station water samples in the dark container for evaluating effects of the dredging was harvested. Water Sampling were collected from Imam Khomeini Port of Musa Bay, at 3 times before (Un-Dredging), during (Fresh-Dredging) and after (Post-Dredging) dredging was repeated.Results and discution: The mean DO value decrease from 3.78 to 2.85. Nutrients and Turbidity value increase during the dredging. Our study suggests that dredging may have potentials damages for aquatic environmental while these changes will improve with time shares.
