Cs-137 and Pb-210 based sediment chronology methods, along with an HPGe gamma-ray spectrometry system, were applied to estimating of sediment accumulative rates (SAR), sedimentation rate (SR) and sedimentation chronology in the Anzali Lagoon. Sedimentation chronology was calculated according to the Pb-210(ex) based-models including; the constant rate of supply, constant initial concentration and Cs-137 peak-technique. The SAR value were ranged from 0.12 g cm(-2) year(-1) in core-2 to 0.21 g cm(-2) year(-1) in core-3. The results showed that the average of SR and SAR values after 1986; interval were 22% and 54% more than between 1963 and 1986 intervals.
