Estudo do transporte de sedimentos em suspensão ao longo da bacia hidrográfica do rio Meia Ponte – Go

Abstract

The present work show with objetive understand of hydrosedimentological dynamics in rivers of the Meia Ponte River Basin, localized in the State of Goias, Brazil. For the development of the work, samples of suspended sediments were collected in six sections, as well as hydrological surveys through the ADCP equipment. The samples were made during the dry season at the end of July, and November during the rainy season, both referring to the year 2018. The results indicate that the suspended sediment soncentration in the BHRMP rivers ranged from 2,62 to 21,69 mg/l, transporting on average 6,31 tons/day of suspended sediments and 25,64 tons/day of total solid discharge during dry season. In the rainy season the suspended sediment concentration ragend from 39,02 to 127,58 tons/day, carrying a solid suspended solid discharge of 401.75 tons/day and a total solid discharge of 868.90 tons/day. The variation is related to the pluviometric seasonality that provides alteration of the critical speeds that remobilize and transport the sedimentary material.
