Modelagem Hidrodinâmica Como Ferramenta De Apoio À Gestão Hídrica Do Rio Tapajós

Abstract: As crescentes demandas pelo uso da água têm agravado a quantidade e qualidade desse recurso vital à vida e, aliadas a eventos naturais extremos, podem intensificar a degradação dela. Diante disso, este estudo tem como objetivo analisar os eventos extremos máximos de vazões de um trecho do rio Tapajós, por meio da modelagem hidrodinâmica. Avaliou-se o potencial de utilização desta ferramenta inovadora dentro do processo de gestão e planejamento dos recursos hídricos. Para tal, lançou-se mão do modelo HEC-RAS, o… Show more

“…There is an increase in the river's average sediment content, from further upstream to the mouth, where the highest concentration of sediment is observed. According to Silva et al (2021), in their hydrodynamic modeling study of the Tapajós River, it was found that in the stretch between points 4 and 3 there was an abrupt reduction in the levels of the water depths, which is justified by the slope of the bottom of the channel averaging 0.00021 m/m. The other stretches (points 5 and 6) had an average slope of 0.00013 m/m, i.e.…”
