The canal is filled with blocky clay indicating reduced to non-existent flow. Canal 1 truncates active intermittent channels from nearby alluvial cones (see US 7, 11, 12, 13) d) Stratigraphic description of Canal 1 in trench 2, downstream of its intersection with intermittent streams. a) Location of the hydraulic structure studied (Canal 1) and trenches 1 and 2 dug perpendicular to its alignment b) View from the east of Trench 1 and description of the environmental dynamics encountered c) Stratigraphic description of Trench 1. As water systems are structural elements of the spatial and socio-political organization of societies, this approach will provide elements to discuss the relative impact of human and/or environmental factors on landscape change and cultural shifts, and measure the long-term vulnerability and resilience of agricultural communities to regional environmental changes.Įxample of the significance and origin of deposits in hydraulic structures (lower Salt River valley, Phoenix, Arizona e Phoenix Sky Train ® project U:9:28 e Fig. While they can be applied to different environmental contexts, they will be presented through the example of Hohokam irrigation systems in the semi-arid Phoenix basin, Arizona, where this approach has been applied as a whole. The principle and limits of the methods applied to this research object are presented and discussed in this paper. This socio-environmental signature recorded in the spatial organization, sedimentary fill and profile of hydraulic structures can be reconstructed by means of a systemic cross-disciplinary approach (geoarchaeology, chronology and paleoenvironment). Their temporalities (construction, maintenance, abandonment) represent an image of a social, cultural, economic and political context as well as changing environmental conditions.
