Abstract: Abstract In contrast to a recent interpretation of delta coast stability1, we now show that the northeastern Nile delta in Egypt has been actively sinking relative to the sea during the recent Holocene epoch. The northern Nile delta is only about 1 m above sea level, making the northern Suez Canal and coastal cities of Port Said and Port Fuad (combined population nearly 500,000) highly vulnerable. Subsidence and world sea-level rises contribute to coastal erosion, incursion of salt in the groundwater underlying the delta plain, and silting problems in the canal entrances2. These processes must be considered when implementing protection measures for this area.
