Resumo


The aim of this study was to analyze the sedimentation rates of suspended material and to estimate the lifetime of the Cachoeira de Cima reservoir, in Mogi Guaçu municipality, Sao Paulo State. Sedimentation chambers were used to collect samples of suspended material. Sedimentation rates for total suspended material (TSM) ranged between 0.27 and 40.70 mg cm-2 d, for inorganic suspended material (ISM), between 0.05 and 34.19 mg cm-2 d, and organic suspended material (OSM), between 0.18 and 6.52 mg cm-2 d. Sedimentation rates of TMS, IMS and OMS at the Cachoeira de Cima reservoir are higher in the rainy season. The lifetime of the reservoir is estimated at 75 years.
