PREHISPANIC HYDRAULIC DAMMING ON THE WESTERN SIDE OF THE CORDILLERA NEGRA, ANCASH, PERÚ
LOS REPRESAMIENTOS HIDRÁULICOS PREHISPÁNICOS EN EL FLANCO OCCIDENTAL DE LA CORDILLERA NEGRA, ÁNCASH, PERÚ
Jesús Maza and Andy Combey
This article presents a study of the hydraulic structures -known as dams- in the Jimbe River sub-basin of the headwaters of the Nepeña Valley (Ancash), based on systematic surveys carried out in that sector. This study allowed for recording 14 pre-Hispanic dams in three different sub-valleys. The morphological and spatial analysis of these hydraulic systems suggests differentiated management of water on the western side of the Cordillera Negra and provides evidence for a reassessment of land use strategies set up by Sierra people during the late pre-Hispanic Period.
