Resumo: The Constant Flux: Constant Sedimentation (CF:CS) and Constant Rate of Supply (CRS) of unsupported/excess 210Pb models have been applied to a 210Pb data set providing of two sediments profiles (GUA-T1 and GUA-T2) sampled at Guarapiranga reservoir, in the Metropolitan Region of São Paulo city, São Paulo State, Brazil. Sedimentation rates obtained by the CF:CS model corresponded to 9.3–12.3 and 30 mg.cm− 2yr− 1, respectively, for profiles GUA-T1 and GUA-T2, indicating a better chronological performance relatively to that of the CRS model in the study area, also allowing successful estimates of the P fluxes in the reservoir.
