Estuaries play an important role in exchanging water and providing a navigational pathway for ships. These zones are very sensitive and vulnerable to any interventions in coastal dynamics. Almost major of these inlets experience coastal problems such as severe erosion, and accretion. Rosetta promontory is an example of this environment. It suffers from many coastal problems as erosion problem along the coastline and siltation problem inside the inlet. It is due to lack of water and sediment resources as a side effect of constructing the Aswan High dam. The shoaling of the inlet leads to hindering the navigation process of fishing boats, negative impacts to estuarine and salt marsh habitat and decrease the efficiency of the cross section to transfer the flow during emergencies to the sea. This paper aims to reach a new stability condition of the promontory by using some coastal measures. These coastal measures include adding a diverted flow, modify the inlet cross section by using centered jetties, eliminate the coastal dynamic in the entrance using boundary jetties. This target is acheived by using a hydrodynamic model Coastal Modeling System (CMS). Extensive field data collection is used to build and calibrate the model. About 17 scenarios were investigated to reach a suitable solution that mitigate the coastal problems at the inlet.
