Mainar is a municipality located in the province of Zaragoza, Aragon, Spain. According to the 2004 census (INE), the municipality has a population of 162 inhabitants.
This town is located near the Sierra de Algairén in the comarca of Campo de Daroca.
Located in a small mound at the end of the plain of the same name, it is circumcised by the foothills of the Algairén mountain range, Bodegones mountain range, Pilones mountain range (also known as the Modorra Mountain Range) and Peco Mountain range.
Huerva river crosses the municipality of Mainar, which forms the border with the town of Villarreal de Huerva.
There is also the Villarroya stream (known Valsáuco on many maps) and Villarpardo stream. two streams, although geographically known as they are not geologically because they are the result of human activity. They were created the twelfth and thirteenth centuries in drainage channels (grooves) excessively wet, and therefore are not suitable for cultivation. This can be checked by looking at the long straight sections prospective currents and perfect angles and even the cobblestones of the current in many sections, it is instead of "El Alcocer" where the artificial production is the most obvious.
The Villarpardo stream is excavated in part by differential erosion and partly by human labor between conglomerates (known as "guijo" "gravel" or "pebble") of the limestone left and right bank. Receives by the left the Rambla (the river), which in turn receives the ravine Valdelacebo left; and gets right to the gorges and Carralanga Carramanchones.
The creek receives the right Sisones the throat; and left the Cañada (throat) Alegría del Tío, the Cañada del Moro (which in turn receives the Cañada de la Vina) and the Cañada del Gordo.
In addition, there are also several irrigation canals (the acequias [irrigation ditchs] "Los Ojos" and "El Reajo"); in fact, two small drainage channels, which prevents the water is used for irrigation.
An example of irrigation created exclusively for irrigation canal is the Agua Somera Somera or Vega ( "shallow" and "superficial plain"), probably from medieval times.
Special mention are the ravines ( "Barrancos") running in the town, the most important are those that flow into the Huerva river on its left bank: Barranco de la Fuente del Piojo, Barranco del Ontazo Barranco del Pozo Ropera ( formed by the union of the Barranco de los Bodegones with Dehesilla Barranco) Barranco del Despeñadero (formed by the union of the Barranco del Molinillo and Barranco Oscuro) and Barranco de Valdefrasno.
