The present work show an analysis of hydrosedimentological dynamics in rivers of the River Basin Meia Ponte (BHRMP), localized in the State of Goias. The work was objective to analyze the sedimentological behavior as a way of understanding the river processes in the studied rivers. For the development of the work, were collected sediment in suspension in six rivers of the basin were collected in at least three points in each river. Hydrological surveys were carried out with ADCP equipment. For the granulometric distribution was used MASTERSIZER 2000 and the LISST – SL equipment. The samples were made during the dry season, at the end of July and November during the rainy season. The samples were submitted to laboratory analysis, which allowed the interpretation and discussion of the results afterwards. The granulometry of suspended sediments had their greatest representativity in the silt class. From the collected data, the Suspended Sediment Concentration in the BHRMP rivers ranged from 2,62 to 21,69 mg / l, transporting on average 6,31 tons/day of suspended sediments during dry season. In the rainy season the suspended sediment concentration ragend from 39,02 to 127,58 tons/day. From the calculations of specific sediment production, it was found that the basin produced 1,72 and 58,18 ton/km2/year form the dry to the rainy season respectively.
