Cataratas do Iguaçu

20

A palavra Iguaçu significa “água grande“, na etimologia tupi-guarani. As Cataratas são formadas pelas quedas do rio Iguaçu. Dezoito quilômetros antes de juntar-se ao rio Paraná, o Iguaçu vence um desnível do terreno e se precipita em quedas de até 80 metros de altura, alcançando uma largura de 2780 metros. Sua formação geológica data de aproximadamente 150 milhões de anos, porém a formação do acidente geográfico das cataratas se iniciou a aproximadamente 200 mil anos.

O rio Iguaçu mede 1200 metros de largura acima das cataratas. Abaixo, estreita-se num canal de até 65m. A largura total das Cataratas no território brasileiro é de aproximadamente 800m e no lado argentino de 1900m. A altura das quedas varia de 40 a 80 metros. Dependendo da vazão do rio, o número de saltos varia, atingindo um número superior a 100 nos períodos de média vazão.

A vazão média do rio fica em torno de 1.500 m³ por segundo, variando de 500 m³/s nas ocasiões de seca a 8.500 m³/s nas cheias. O volume maior de água ocorre entre os meses de outubro a março.

Os principais saltos são 19, cinco deles do lado brasileiro (Floriano, Deodoro e Benjamin Constant, Santa Maria e União) e os demais no lado argentino. A disposição dos saltos, com a maior parte deles no lado argentino e voltados para o Brasil, proporciona a melhor vista para quem observa o cenário a partir do Brasil.
