A suite of drill cores undertaken on the Saqqara-Memphisfloodplain revealed an array of Late Pleistocene-Holocene sediment facies that show a complex of spatio-temporal changes in sediment related to migration of the River Nile, Nile flood variations, settlement sites and climate change. The recovered data enhance our understanding of the history of the modern River Nile and its relationship to the emergence and continuity of Egyptian civilization. The floodplain of the Saqqara-Memphis area reveals a sequence of aggradation and degradation events comprising six clearly marked sedimentary units (I-VI), overlying Late Pleistocene fluvial sand and gravel (unit I). Deposition of unit II resumed during a period of high Nile flow, rapid sea level rise and locally wet climatic conditions. As a result, the floodplain was occupied by swamps and anastomosing channels. Subsequently, the Nile changed to a more stable meandering channel system with well-developed levees and flood basins (unit III). This aggradation unit was subsequently eroded by the end of Old Kingdom (ca. 4.2 kyr cal BP). The degradation hiatus was followed by a widespread layer of alluvial silt and sand indicating very high Nile floods that coincide with historical records of very high floods during the Middle Kingdom and frequently high floods during the New Kingdom (unit IV). During the last two thousand years (units VI-VII) floods generally diminished except for several notable lows and highs. Our calculations of the long-term rate of siltation during the Middle and Late Holocene suggest an average rate of 0.235 m/century rather than the commonly cited 0.09e0.12 m per century. In addition, our study of satellite imagery of the Memphite region in the context of archaeological data combined with our own geological studies reveal that the main Nile in Neolithic and Predynastic times (ca.7.0 e5.0 kyr cal BP) ran along the eastern edge of the current floodplain. A lateral branch of the Nile ran along the western edge of the floodplain. It is on the bank of this branch that the first capital of a unified Egypt was established. Our cores also reveal during the Dynastic period, the western branch shifted eastwards, while the main Nile shifted westwards.
Studies done recently in the Nile Delta, which is considered to be the part of Egypt most threatened by urbanism and agricultural pressure, gives rise to new ideas about human occupation during the Predynastic and the Early Dynastic periods (4 th millennium BC). In the Samara area, 40 km south-east of Mansura, a multidisciplinary team has initiated a research program on the period of state formation in Egypt. Geomorphological studies undertaken in the Kom el-Khilgan area made it possible to recognise that the site exists on a levelled sandy residual hill which provided high ground above the floods in the 4 th millennium BC. From the example of Kom el-Khilgan, to which several geoarchaeological techniques have been applied (geological profiling, classical hand augering, geoelectrical profiling and sounding) the aim of this study is to propose a model of the human occupation in the Nile Delta and to locate the sites into their archaeological regional context.
In the Theban area around modern Luxor (Egypt), the River Nile divides the temple complexes of Karnak and Luxor from New Kingdom royal cult temples on the western desert edge. Few sites have been archaeologically identified in the western flood plain, despite its presumed pivotal role in the ancient ritual landscape as the territory that both physically divided and symbolically connected the areas inhabited by the living and the areas occupied by the dead. Using borehole data and electrical resistivity tomography, the current investigation of subsurface deposits reveals the location of an abandoned channel of the Nile. This river course was positioned in the western, dis-tal part of the Nile flood plain. Over 2100 ceramic fragments recovered from boreholes date the abandonment of the relatively minor river channel to the (late) New Kingdom. This minor river branch could have played an important role in the cultural landscape, as it would have served to connect important localities in the ritual landscape. Changes in the fluvial landscape match with established periods of basin-wide hydroclimatic variability. This links cultural and landscape changes observed on a regional scale to hydroclimatic dynamics in the larger Nile catchment, in one of the focal areas of Ancient Egyptian cultural development.

The Dynamic Landscape of the Western Nile Delta from the New Kingdom to the Late Roman Periods
"Archaeological sites are often recognized as the basis for studies of the cultural landscape, even as many have noted that the site concept itself has become more fractured over time. In Egypt, different meanings of the term have been cultivated over two centuries of scholastic practice and heritage law, though surprisingly it has rarely been applied to investigations of regional settlement in the Nile floodplain, particularly the Delta. Such a circumstance stands in direct contrast to the Delta’s potential contributions to a fuller narrative of Egyptian culture. In considering the archaeological and geoarchaeological record of the western Delta, this research draws together historical cartography, remote sensing data, prior archaeological work, and ancient texts to investigate its cultural and natural landscape. Fragmented information on relict channels from Shuttle Radar Topography Mission, Corona satellite imagery, and British Survey of Egypt maps informed a program of drill augering to investigate and confirm several observed distributaries of the Rosetta and Canopic branches. Prior archaeological work by the Egypt Exploration Society Delta Survey, the Naukratis Project regional survey of the 1970s and 80s, and others guided systematic surface collection that elucidated spatial distribution of ceramics on several elevated mounds (koms) occupied from the New Kingdom to Late Roman periods (1535 B.C.E. – 650 C.E.). Simultaneously, surface collection units and drill augering transects were arranged both within and beyond the visible extents of koms in order to test hypotheses about site extent. Moreover, detailed topographic survey coupled with observations of Quickbird-2 satellite imagery allowed for theorizing about subsurface architecture and modeling patterns of kom and site preservation. By exploring the promise of surface collection and other minimally destructive means of analysis, this study proposes an integrated methodology for investigating the cultural and natural landscape of the Nile floodplain, taking tentative steps towards more fully realizing the tremendous, largely untapped potential of the sown lands of Egypt."

Rivers, changeable features of earth surface and in the meantime fixed conspicuous elements of any landscape, have been chiefly chosen by human settlements as natural corridors for their expansion, trade and culture. Nile is a paradigmatic example of such a twofold function of water courses, having created with its peculiar regime of discharge suitable conditions for the development of a great civilization which played a central role in the man history. Significant examples of geo-archaeological researches, conducted for more than 20 years along the Nile valley, will be reported and commented, taking into account their representativeness and distribution in time and space.
