In the mesquite-studded desert valley southeast of Phoenix, excavations have revealed a surprisingly developed ancient farming culture that lasted from several centuries before the birth of Christ to A. An ancient system of hand-dug canals -- the earliest dating from as far back as 300 B. -- extends for miles throughout Arizona's Salt River and Gila River valleys. The Hohokam people, named after a modern Pima Indian word meaning "that which has vanished," are believed to have been the first irrigationists in what is now the United States.In particular, the recent preliminary results lead to two hypotheses, which, if supported, would indicate a transformation of irrigation management at a time of fundamental change in other aspects of Hohokam society: A lack of support for these hypotheses would single out the Hohokam case as one following a developmental trajectory not recognized elsewhere in the world.The two hypotheses will be tested by dating the canals and monitoring the canal system’s configuration on the landscape as it changed over time.

In contrast, some preliminary excavation results from approximately 100 main canals in Canal System 1, the largest of the ancient irrigation complexes, hint that the Hohokam case may be more in line with theoretical expectations than previously thought.The history of Canal System 1 will be reconstructed using some recent and particularly fortuitous excavations in the Riverview project area, through which passed virtually all of the main lines in the system.The Riverview data will be matched with decades of excavation results from various other parts of Canal System 1 to trace the canal routes from head to terminus.We find that politically centralized, acephalous, and private forms are implausible in the Hohokam context. We find no ethnographic basis for positing a valley-wide management system.Este trabajo presenta los resultados de una yuxtaposición entre hallazgos arqueológicos sobre la irrigación Hohokam e investigación etnográfica sobre la organización social en sociedades agrícolas que emplean sistemas de irrigación.
