The greater Cairo area has many islands formed after the Aswan High Dam construction. Ministry of water resources and irrigation is interested in studying the development and evolution of these islands in order to reflect the esthetic aspects and improvement of the environment surrounding the islands. This study focuses on Shubra El-Khaima Island which is located upstream Delta Barrage in the back water curve region. The study aims to propose different alternatives for island development. GSTAR3.0 model is the most recent version of a series of numerical models for simulating flow of water and sediment transport and prediction of morphological changes in alluvial rivers. This model was used to simulate and examine different alternatives for Shubra island development on river morphology according to different discharges scenarios. The optimum alternative was proposed. Also, the future required precautions to mitigate the effects of this development on the stability of watercourse were suggested.
