Study on hydrodynamics and sediment transport in Imam Port

In order to increase the berthing capacity of East-West jetties of Imam Port in the north-western part of Persian Gulf, two series of field measurements are carried out. The area behind the east-west jetties is going to be nourished and authorities are seeking the consequences of the filling on the sedimentation of the neighbouring areas. So the permeable piers of jetties will convert to solid quay walls and there would be no more current in the back area of jetties. In this regard, current velocity measurements by implementing three sets of ADCP instrument is carried out during 15 days, which cover a cycle of semi-diurnal tidal cycle of the study area. Also sea water sampling by using a Multi- Limnos device accomplished throughout two 25-hours period, in the neap and spring tide respectively. Results of ADCP current velocity measurements show that the pattern of water is almost tangent to the direction of east-west jetties and there is no transverse movement of water into the back area of jetties. So the primary judgement of filling the intermediate basin is that there would be no specific changes in the sedimentation pattern of the neighbouring areas.
