In October 1957, the Turia River overflowed its banks in Valencia, Spain, causing at least 81 deaths and extensive material damage. Some sources suggest the death toll may have been higher. The flood brought about 300 liters of water per square meter in 24 hours, with a flow estimated at 3,700 cubic meters per second. Entire neighborhoods, including Campanar and the maritime poblados, were affected. This was not the first flood in the region, as there had been about 75 recorded floods over the previous 700 years. After the disaster, three possible solutions were considered: the North Plan, which would divert the river north; the Central Plan, involving a dam at Vilamarxant; and the South Plan. The South Plan was approved by the Council of Ministers on July 22, 1958. The river was diverted west of the city, near Quart de Poblet, to reach the sea through a mouth placed approximately 3 km further south. The new channel, 11,868 kilometers long and 175 to 200 meters wide, was designed to handle 5,000 cubic meters per second of water, well above the 3,700 cubic meters per second recorded in 1957. Construction began in February 1965 and was officially completed on December 22, 1969. However, the project faced opposition, with Quart de Poblet and Mislata protesting the route. Environmental consultant Antonio Estevan later questioned the need to divert the entire river. The old riverbed, now dry, crosses the entire city. As early as 1966, while the South Plan construction was still underway, discussions about the future of the old riverbed began. The City Council and the government considered building a major communication axis linking the port to the airport, which would have involved an urban highway within the riverbed. However, residents responded with the slogan, "El llit del Túria és nostre i el volem verd" ("The Turia riverbed is ours and we want it green"). The road project was eventually abandoned, as the bypass made the idea obsolete. In 1986, a park opened along the riverbed, covering 136 hectares and nearly 8.5 km, equivalent to about 190 football fields. Ricardo Bofill designed one of its central sections. The park is estimated to welcome 3 to 7 million visitors per year, with the highest figure exceeding the population of Norway (about 5.5 million inhabitants). Historical bridges, including the Mar Bridge, which dates back to 1591, now span walkways lined with palm trees, orange trees, and pines. The park connects the Ciudad de las Artes y las Ciencias to the Bioparc. By moving the river away from the city, Valencia gained a park that runs through the city from end to end. In October 2024, ten days before the anniversary of the 1957 flood, the new channel carried floodwaters as planned. The Poyo ravine, another basin, flooded the southern communes. Experts consulted by Maldita.es differ on the exact role of the new channel during the DANA (a meteorological phenomenon involving heavy rain). However, they agree on one point: a large part of the damage is due to construction in flood-prone areas.
