After three days of heavy rain, the Turia overflowed and flooded the city of Valencia, Spain, causing at least 81 deaths.

The Turia or Túria is a river in Spain, which has its source in the Montes Universales in the mountain ranges of the northwesternmost end of the Sistema Ibérico, Teruel province. From its source to roughly the city of Teruel, it is called Guadalaviar river. It runs through the provinces of Teruel, Cuenca and Valencia, and discharges into the Mediterranean Sea near the city of Valencia. The river formerly ran through the center of the city but was diverted south of the city to prevent flooding.

A flood on 14 October 1957 in Valencia, Spain, resulted in significant damage to property and caused the deaths of at least 81 people. In response to the tragedy, the Spanish government devised and enacted the Plan Sur, which rerouted the city's main river, the Turia.

Valencia, formally València, is the capital of the province and autonomous community of the same name in Spain. It is located on the banks of the Turia, on the east coast of the Iberian Peninsula on the Mediterranean Sea. It is the third-most populated municipality in the country, with 825,948 inhabitants. The urban area of Valencia has 1.5 million people while the metropolitan region has 2.5 million.
