Estimativa De Produção E Trasporte De Sedimentos Na Bacia Hidrográfica Do Rio Parnaíba, Nordeste Do Brasil

Abstract: O presente trabalho teve como objetivo avaliar a produção e transporte de sedimentos na bacia hidrográfica do rio Parnaíba. Para tanto, foram calculados os valores de descarga total sólida a partir das séries históricas de vazão e concentração de sedimentos em suspensão registrados pelas 12 estações fluviométricas instaladas nos principais rios da bacia do Parnaíba. Concluiu-se que: (i) o setor superior da bacia do Parnaíba constitui-se a principal fonte de sedimentos, com uma produção específica da ordem de 7… Show more

“…The analysis of data on the sediment yield and transport in the Parnaíba river watershed offers a valuable analytical perspective on erosion processes in the region. The data provided in the article by Morais (2015) [69], which highlights the upper sector of the Parnaíba River basin (downstream) as the main source of sediment with a specific production of 94.8 t/km 2 /year, are complementary and benefit the discussion of the results obtained by the RUSLE.…”
