Río Otún vs Rosario

Informations

The Otún River (Río Otún) is a river in the Risaralda department of Colombia. Its source is Lake Otún, fed by meltwater from Nevado Santa Isabel, and its outlet is the Cauca River. The Otún River passes between the cities of Pereira and Dosquebradas, and is crossed at that point by the César Gaviria Trujillo Viaduct, one of the largest cable-stayed bridges in South America. The Otún River is the only source of drinking water for Pereira and Dosquebradas.

The local water company takes about 1.8 cubic metres per second (64 cu ft/s) from the river at a site known as Nuevo Libaré. Agricultural development in that region has affected the quality of the water from the river, with pig and chicken farms as well as human waste water being major sources of bacteriological contamination.[1]The river passes through several protected zones including the Otún Quimbaya Flora and Fauna Sanctuary.

Rosario (Spanish pronunciation: [roˈsaɾjo]) is the largest city in the central Argentina province of Santa Fe. The city is located 300 km (186 mi) northwest of Buenos Aires, on the west bank of the Paraná River. Rosario is the third-most populous city in the country, and is also the most populous city in Argentina that is not a capital (provincial or national). With a growing and important metropolitan area, Greater Rosario has an estimated population of 1,700,000 [1]as of 2020. One of its main attractions includes the neoclassical, Art Nouveau, and Art Deco architecture that has been retained over the centuries in hundreds of residences, houses and public buildings. Rosario is the head city of the Rosario Department and is located at the heart of the major industrial corridor in Argentina. The city is a major railroad terminal and the shipping center for north-eastern Argentina. Ships reach the city via the Paraná River, which allows the existence of a 10-metre-deep (34 ft) port.

The Port of Rosario is subject to silting and must be dredged periodically. Exports include wheat, flour, hay, linseed and other vegetable oils, corn, sugar, lumber, meat, hides, and wool. Manufactured goods include flour, sugar, meat products, and other foodstuffs. The Rosario-Victoria Bridge, opened in 2004, spans the Paraná River, connecting Rosario with the city of Victoria, across the Paraná Delta. The city plays a critical role in agricultural commerce, and thus finds itself at the center of a continuing debate over taxes levied on big-ticket agricultural goods such as soy. Along with Paraná, Rosario is one of the few Argentine cities that cannot point to a particular individual as its founder. The city's patron is the "Virgin of the Rosary", whose feast day is October 7.
