Abstract: This research aims to evaluate the hydraulic properties and processes of erosion and sedimentation that would arise in the evaluation section of the Napo River and the confluence with Mazan River. As the first of Amazonian rivers, it has an unstable regime state that sharpens its geodynamics, located on the other side of Mazán port, apparently has no influence and can be indifferent today. However, with the analysis changes during this work will be denoted in the bed and concentration of non-uniform sediments erosive velocities and discharges very near the“Señor de los Milagros”Island. At different discharges, flow patterns of Mazan River and main branch of the Rio Napo determine a result that allows the flow to act normally, arriving at the port with velocities that allows calm setting near the port. On the other hand, island Lord of Miracles suffers erosion process due to the presence of erosive left channel and the loss of its extension to flow routed to Puerto Mazán, forming and accelerating erosion on its banks.
