Abstract
Kolata and Ortloff examine the distribution, morphology, and function of raised fields through survey, aerial photography, and excavation of raised fields and their associated canals. Both the Catari and Tiwanaku river valleys were examined. The results of the excavations and some stratigraphic profiles are presented. The authors explore the reasons why raised fields work so well and some of the problems they overcome (salinization, drainage of saturated soils, increasing agricultural land area, heat storage, and soil fertility). They develop a mathematical model to explore the physical phenomena involved in heat storage in raised fields along with a hydraulic analysis of some of the canals and aqueducts.
