Early water management systems on the southern Transjordan plateau

Abstract

[eng] The efficient management of water resources to supply the needs of societies in territories where water is a scarce and limited resource has been essential throughout time. The site of Sela on the southern Transjordan plateau is unique for understanding water management in this semi-arid area. The analysis of hydraulic installations has allowed us to characterise its hydro technology and spatial distribution in the settlement. To this end, the hydraulic facilities have been identified, documented, and analysed in detail through two archaeological surveys (2015 and 2016). Spatial analysis has been carried out by preparing extensive 2D planimetry and 3D reconstructions. The results obtained have made it possible to reconstruct the water supply system necessary for the subsistence of the societies that inhabited Sela over time. The system consists of canals, cisterns, and sedimentation basins for the collection, conduction, storage, and preservation of water, mainly from rain. Some of Sela’s hydraulic structures may have originated in the Bronze Age (mid-late 2nd mill. BCE), but more secure dating is needed to substantiate this possibility.
