(Sediment Transfer through the Fluvial System – Proceedings of a Symposium held in Moscow, August 2004 – IAHS Publication 288, 2004, pp. 332–355).
The results of a study on the sedimentation in Tucurui Reservoir, located in the lower reaches of the Tocantins River, Brazil, are presented. Morphological information on reservoir sediment deposits and sediment transport data collected since dam closure in 1984 were utilized. These data were used to construct an empirical model of reservoir sedimentation that allowed an assessment of the impact of land use change upstream Tucurui Dam. Results of the model show there is not any short or medium term problem regarding the development of sediment deposits at the water intake sill of the reservoir. Future work on topographic surveys in the river and sedimentological studies in the reservoir are recommended.
