The archaeology of irrigation canals, with special reference to Peru

Abstract

Abstract A research methodology for the study of prehistoric irrigation canals is suggested which uses detailed excavation and survey techniques to generate data suitable for analysis by the principles of open channel hydraulics. The results indicate that these principles were empirically understood, even when the question of transporting water down steep slopes is considered, and that prehistoric canal discharge was a function of the farmer's perception of the hydrology of the agricultural system.
