During all its periods, Egyptian society has maintained a privileged relationship with the Nile: the location of housing, and temples has been dictated by the river's course and agricultural land has benefited from the Nile's floods. The understanding of the management of alluvial areas is mainly based on the analysis of the results of archaeological excavations or epigraphic data; geomorphological analyses to reconstruct the fluvial environment of the Nile are still few and often disconnected from the archaeological problems. The aim of this research is the reconstruction of the Nilotic socio-ecosystem of a part of Luxor west bank (called since antiquity "Memnoneia") during the Ptolemaic period (3rd-1st centuries BC.) using a new transdisciplinary approach. This latter combines digital cartography, papyrological analysis and fluvial geomorphology. In this perspective, a selection of sources related to the study area has been identified in order to better understand the fluvial environment and the microtopography of this alluvial plain.
