Abstract text Nile Delta is historically targeted for various types of human activities and life needs since the Pharaohs’ era. This is mainly due to the wealth of the natural resources existed at the Deltas in its creation including fresh water, flat fertile soils, recreation places, mineral resources, coastal lakes and fish farming. This attracted an excessive increase in population, civilization and accompanied developmental plans to accommodate such population growth. Geologically, the Nile Delta formed by progression of a complex system of deltaic fans throughout the Pleistocene, with the Modern delta being formed from sediments supplied by at least ten distinct distributaries throughout the Holocene. The land subsidence of the northern delta has become a topic of major concern to the Egyptian population and government, reaching up to 10 mm/year. Maximum estimated land subsidence levels are in the eastern part of the Nile delta. Hence it creates major impact on the infrastructure and development in the area. Moreover, it is worsen the impact of sea level rise due to climate change; since the cumulative subsidence together with the scenarios of sea level rise will double the coastal flooded area. In the present work we utilize SNAPPING service on the Geohazards Exploitation Platform (GEP) to monitor the spatial and temporal patterns, as well as the magnitudes of urban land subsidence in the Nile Delta. We are aiming to explore and document the potential of Earth Observation platform-based solutions as an operational tool for measuring and monitoring of land subsidence at millimeter level accuracy over wide areas such as the whole Nile Delta.
