Jalón (Río)

"El río Jalón es un río del nordeste de España, uno de los principales afluentes del río Ebro. Tiene una longitud de 224 km y drena una amplia cuenca de 9338 km². Su caudal en Calatayud es de 20,8 m³/s, pero es muy irregular al ser un río de régimen pluvial mediterráneo."

"The river Jalón (Latin: Salo) is located in the northeast of Spain, and is one of the principal tributaries of the Ebro. It has a length of 224 kilometres (139 mi) and drains a watershed of 9,338 square kilometres (3,605 sq mi). The flow rate in Calatayud is 20.8 cubic metres per second (730 cu ft/s), but is highly irregular due to the great range of Mediterranean rainfall patterns. The course of the river forms the main communication route between the Castilian Plateau and the Ebro. Until the late twentieth century, roads and railways between Madrid and Zaragoza followed this path."
