Quebrada Debris Flows, Hydrology, and Agriculture at Tacahuay Tambo

Summary

This is an abstract from the "SAA 2021: General Sessions" session, at the 86th annual meeting of the Society for American Archaeology.

This poster presents a survey of the debris flow deposits, hydrology, and agriculture at Tacahuay Tambo, a Late Intermediate (1000-1476 AD) site located on south coast of Peru. Quebrada Tacahuay in combination with the Tambo, has 12,000 years of cultural history. Therefore, there are numerous flood deposits that add to the complexity of the stratigraphy. Debris flows are especially impactful in this area when paired with tectonic events that loosen up existing rocky material. The Miraflores Event (14th century AD), was one of these major disasters that impacted cultural activity in this region. Deposits from this flood can be found in the Tacahauy quebrada. Using GPR techniques, sediment analysis, and GIS mapping of the hydrology of this drainage, I studied sediment deposition, drainage, and disaster management at this site. In addition, a survey using drone footage was used to locate agricultural terracing around to show the potential impact of flood events on the people who inhabited this area. This initial survey provides the geologic context for future excavations at Tacahuay to fully understand the relationship between environmental change and the Chiribaya people during the LIP.
