RESUMO

The knowledge of the processes involving the transport, deposition and suspension of sediment in rivers is of vital importance in the conservation, development and utilization of water resources and the environment. Meanwhile, in Brazil, which has based the hydropower energy, has not given proper consideration with regard to sedimentation due to the difficulty in acquiring such data and costs involved. So this research aimed to define the needs on the accuracy, ease, cost and frequency of data acquisition for the supply of sediment in rivers, identifying current technologies and promising technologies that will be available on short notice to meet those needs.
