Júcar
river in Spain
The Júcar (Spanish: [ˈxukaɾ] ) or Xúquer (Valencian: [ˈʃukeɾ]) is a river in Spain, on the Iberian Peninsula. The river runs for approximately 509 kilometres (316 mi).
Its source is located at Ojuelos de Valdeminguete, in the municipality of Tragacete, province of Cuenca, on the eastern flank of the Montes Universales in the Sistema Ibérico. Its tributaries include the Cabriel, the Magro, and the Albaida.
The Júcar River flows first southward and then eastward through the towns of Cuenca, Alcalá del Júcar, Cofrentes, Alzira, Sueca, Alarcón and Cullera, a town located near its mouth into the Gulf of Valencia in the Mediterranean Sea. It crosses the provinces of Cuenca, Albacete and Valencia. On the mid-course of the river, it is impounded by the Cortes-La Muela Reservoir near Cortes de Pallás.
In 1982, the river Júcar broke the Tous Dam, causing the biggest flood in Spanish history, with a flow speed of 16,000 cubic metres per second (570,000 cu ft/s), killing more than 30 people. This flood was the most important one in the whole history of Spain because, at that time, the people had thought that the Tous Dam was indestructible. The flood was called La pantanada de Tous (which, in English, would translate something like: The Swamp of Tous).

Why this record matters
A short description can identify a subject without explaining its stakes. For “Júcar”, the useful work is to connect “river in Spain” to the records capable of establishing context and consequence.
Place names and jurisdictional language are key evidence: both can reveal earlier catalogue descriptions and overlooked record series. The source revision retrieved here is dated Aug 3, 2026. The linked authority identifier is Q14311. VIAF identifies the subject as 244117170. The Library of Congress control number is sh85070832. Authority coordinates are 39.173, -0.295. 4 of 5 selected statements include explicit references; 2 carry qualifiers and 0 use preferred rank. The first chronological checks are 1982.
A single description cannot reconcile every naming convention, rebuilding phase or administrative transfer associated with a place. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
