Resumo: 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. Keywords: Hydrosedimentology. Solids in suspension. Fluvial Dynamics.

Pour le développement du levé, des échantillons de sédiments en suspension ont été prélevés le long de six sections fluviales du bassin hydrographique, ainsi que des levés hydrologiques à l'aide de l'équipement ADCP. Les collectes ont été effectuées pendant la saison sèche, fin juillet et pendant la période des pluies, au mois de novembre, toutes deux se référant à l'année 2018. Les résultats montrent que la concentration de sédiments en suspension dans les rivières BHRMP variait de 2,62 à 21,69 mg / l, transportant en moyenne 6,31 tonnes / jour de sédiments en suspension et 25,64 tonnes / jour de rejets solides totaux, en saison sèche. Pendant la saison des pluies, la concentration de sédiments en suspension varie entre 39,92 et 127,58 mg / l, entraînant un rejet solide en suspension moyen de 401,75 tonnes / jour et un rejet solide total de 868,90 / jour. La variation est liée à la saisonnalité pluviométrique qui fournit la variation des vitesses critiques qui remobilisent et transportent le matériau. Mots clés: Hydrosédimentologie. Solides en suspension. Dynamique fluvialeO presente trabalho apresenta como objetivo compreender a dinâmica hidrossedimentológica da Bacia Hidrográfica do Rio Meia Ponte (BHRM), localizada no Estado de Goiás, Brasil. Para o desenvolvimento da pesquisa foram coletadas amostras de sedimentos em suspensão ao longo de seis seções de rio, bem como levantamentos hidrológicos por intermédio do equipamento ADCP. As coletas foram feitas no período de estiagem, no final do mês de julho e no período chuvoso, em novembro, ambos referentes ao ano de 2018. Os resultados apontam que a concentração de sedimentos suspensos nos rios da BHRMP variaram de 2,62 a 21,69 mg/l, transportando em média 6,31 ton/dia de sedimentos suspensos e 25,64 ton/dia de descarga sólida total, no período de seca. Na estação chuvosa a concentração de sedimentos suspensos varia entre 39,92 a 127,58 mg/l, transportando uma descarga sólida suspensa média de 401,75 ton/dia e uma descarga sólida total de 868,90 ton/dia. A variação dos resultados adquiridos, mostra-se relacionada com a sazonalidade pluviométrica, que propicia alteração das velocidades críticas que remobilizam e transportam o material sedimentar.
