A "Rû" is an irrigation channel that allows water from melting snow/ice to reach meadows, fields and areas of land that are often left fallow. These channels lead the water to even the remotest and most impoverished places, allowing farmers to utilise every piece of land. Maintenance of these channels was governed by legal institute of the "corvées": pre-set days that beneficiaries of water from the channel had to work during the year. Therefore, along the "rûs" there are numerous pedestrian walkways, together with water control works, such as small enclosures.
