Abstract This paper aims to contribute new data to understanding early Predynastic settlement patterns in Egypt at the beginning of the state formation process in the 4th millennium bce. It focuses on the early settlements of the First Nile Cataract region. We employ three different datasets to address the issue retrieved from a recent archaeological investigation and drill coring and from Nile records available from archaeological and historical sources. The analysis is performed in a gis-based environment and through inundation modelling. Data suggest early Predynastic settlements at the First Cataract may have been settled all year round. They appear to be deliberately placed above the annual high flood level and have water resources for most of the year. The new geo-archaeological data further suggests that the average high inundation level for the early 4th millennium bce was similar to that documented for the end of the millennium.
