BRIEFING NOTES ON THE CIRCE URBAN AND COASTAL CASE STUDIES: ALEXANDRIA (URBAN) AND THE WEST NILE DELTA (COASTAL), EGYPT The city of Alexandria is located to the West of the Nile Delta and shares many of the common issues of the wider coastal region. The justification, research issues and data for both case studies are therefore considered within a single briefing note. Subsequent reports of the impacts of climate change will differentiate between coastal and urban areas of the West Nile Delta.
