Río Otún vs Adelaide

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.

Adelaide (listen) (AD-ə-layd) is the capital city of the state of South Australia, and the fifth-most populous city of Australia. The demonym Adelaidean is used to denote the city and the residents of Adelaide. Adelaide is situated on the Adelaide Plains north of the Fleurieu Peninsula, between the Gulf St Vincent in the west and the Mount Lofty Ranges in the east. Its metropolitan area extends 20 km (12 mi) from the coast to the foothills of the Mount Lofty Ranges, and stretches 96 km (60 mi) from Gawler in the north to Sellicks Beach in the south. Named in honour of Queen Adelaide, consort to King William IV, the city was founded in 1836 as the planned capital for the only freely-settled British province in Australia. Colonel William Light, one of Adelaide's founding fathers, designed the city centre and chose its location close to the River Torrens, in the area originally inhabited by the Kaurna people and known as Tarndanyangga ("place of the red kangaroo"). Light's design, now listed as national heritage, set out the city centre in a grid layout known as "Light's Vision", interspaced by wide boulevards and large public squares, and entirely surrounded by parklands.

Early colonial Adelaide was shaped by the diversity and wealth of its free settlers, in contrast to the convict history of other Australian cities. Until the post-war era, it was Australia's third-largest city. It has been noted for its leading examples of religious freedom and progressive political reforms, and became known as the "City of Churches" due to its diversity of faiths. Today, Adelaide is noted for its many festivals and sporting events, its food and wine, its coastline and hills, and its large defence and manufacturing sectors. Adelaide's quality of life has ranked consistently highly in various measures through the 21st century. As South Australia's government and commercial centre, Adelaide is the site of many governmental and financial institutions. Most of these are concentrated in the city centre along the cultural boulevards of North Terrace and King William Street.
