Modelagem computacional de ressalto hidráulico em canal urbano

Abstract

Com o objetivo de avaliar o processo de transição de regime, apresentam-se discussões sobre a geração de ressalto hidráulico em um canal urbano, avaliando os efeitos da variação de rugosidade das paredes e da declividade longitudinal do canal, por meio de modelagem computacional, utilizando o software HEC-RAS. De forma específica, analisam-se simulações na porção artificial de canal do rio Granjeiro, localizado no município do Crato, no Estado do Ceará, Brasil. Considerando que o canal se caracteriza, longitudinalmente, por dois trechos com declividades diferentes, foram avaliados cenários com diferentes rugosidades da parede do canal. A análise evidenciou que a modificação na rugosidade por meio de uma completa reforma nas paredes do canal desloca a formação do ressalto hidráulico para uma posição 340 m a jusante, mas ainda localizando-se na parte urbana do canal.
