The objective of the present study was to determine key planning curves that represented loads of suspended sediment in the River Piranhas. The study was carried out in the hydrographic sub-basin of Piranhas River. A total of 15 campaigns of hydrosedimentometric measurements was performed, in the period from November 2012 to May 2013, including the measurements of suspended sediment concentration and liquid and solid discharges. Key curves were plotted for sediment in suspension, for the dry and rainy periods, which presented good coefficients of determination.
