Resumo

The hydrossedimentological processes are complex and depend on several factors. The Knowledge of the behavior of bed sediments of the reservoirs, in addition to allowing calculation of retention efficiency and specific gravity of sediment, essential for estimating sediment deposition in a reservoir, assists in identifying the types of existing deposits and allows to define appropriate strategies to control the silting.In this context, this paper presents a study carried out in the reservoir of the Mogi-Guaçu Small Hydroelectric Power Plant (SP) in which the bed sediment was sampled employing the piston core to obtaining samples that were subjected to granulometry analysis. Analyzing the results it was possible to identify sediment deposits with different granulometric characteristics, indicating the need for a better monitoring of the reservoir, thus avoiding the increase of the silting processes, helping in the planning and management of water resources.
