Overview of Iguassu falls
The word Iguaçu means “big water” in Tupi-Guarani etymology. The falls are formed by the falls of the Iguaçu River. Eighteen kilometers before joining the Paraná River, the Iguaçu wins an unevenness of the ground and rushes when dropped up to 80 meters high, reaching a width of 2780 meters. Its geological formation dating from about 150 million years ago, but the formation of the landform of the falls began approximately 200,000 years ago. Iguassu falls
The Iguaçu River measures 1200 meters wide above the falls. Below is a close up to 65m channel. The total width of the Falls on the Brazilian territory is approximately 800m and 1900m on the Argentine side. The height of the falls varies between 40-80 metros. Depending on the river flow, the number of hops varies, reaching a higher number to 100 during periods of average flow.
The average flow of the river is around 1,500 m3 per second, ranging from 500 m3 / s in times of drought and 8.500 m3 / s when heavy. The larger volume of water occurs between the months from October to March, however the record of the highest flow has reached the volume of 46,000 m3 per second in June 2014, just before the world cup kick-off.
The main falls are 19, five on the Brazilian side (Floriano, Deodoro and Benjamin Constant, Santa Maria and Union) and the others on the Argentine side. The arrangement of heels, with most of them in Argentina and Brazil facing side, provides the best view for those who observe the scenery from Brazil. Both sides have to be discovered.
