Abstract: The suka kollus, considered among the most important hydraulic structures of ancestral Andean technology, are used as a technique for crop production in flood-prone soils, enabling subsurface irrigation of crops by means of drainage channels. They also generate a thermoregulatory effect depending on the channel/ridge ratio and the total size of the infrastructure. They could be a valuable way of making use of marginal soils if some of the drainage channels are replaced by underground drains to increase the area of cultivation. This work was therefore undertaken to study the flow of water under a “mixed” drainage system (surface and subsurface drainage) adapted to the suka kollus system.
