  Paraná River - Wikipedia, the free encyclopedia
The Paraná river is formed at the confluence of the Paranaiba and Grande (Rio Grande) rivers in southern Brazil.
Shortly upstream from this confluence, however, the river is dammed by the impressive Itaipu dam, the largest hydroelectric generating station in the world, and creating a massive, shallow reservoir behind it.
The river continues its general southward course for about 468 km (291 miles) before making a gradual turn to the west for another 820 km (510 miles) before encountering the Paraguay River (Rio Paraguay), the largest tributary along the course of the river.

 River - Wikipedia, the free encyclopedia
The lower end of a river is its base level, commonly called its mouth, a river typically widens at its end and forms what is known as a delta or estuary.
Rivers begin at their source in higher ground, either rising from a spring, forming from glacial meltwater, flowing from a body of water such as a lake, or simply from damp, boggy places where the soil is waterlogged.
River management is an ongoing activity as rivers tend to 'undo' the modifications made by man. Dredged channels silt up, sluice mechanisms deteriorate with age, levees and dams may suffer seepage or catastrophic failure.

The two rivers that form the Paraná River begin in the central plateau and run through sedimentary and volcanic rocks of the Paraná and Chaco sedimentary basins, which are bordered on the eastern side by the highlands of the Andes and on the north and east by the Precambrian rocks of the Brazilian Shield.
The rivers that form the Paraná River are similar to other plateau rivers, with an average slope of 0.8 m per km, decreasing in the middle portion to 0.3 m per km.
This trend was verified in all large rivers of this part of the Paraná Basin, providing evidence for the presence of spawning areas in the upper portion of the river and nursery areas in the lower portion.
