Walls to store rainwater

Albarradas are artificial lentic wetlands. They have been known since ancient times in South America as jagüeyes, swamps, dams or simply lagoons. In the coastal region of Ecuador, they are currently known as Albarradas. They are hydraulic constructions that have well-defined earth walls, their shapes are varied: circular, semicircular (horseshoe or circular shape), elongated (with a tail). They are filled through a process of slow accumulation of rainwater, coming from runoff produced by the topography of the land. They can also be filled with water from small channels that are generated in the rainy seasons that may belong to an initial fluvial order.
