RESUMO

The unsteady flow in open channels is described by the Saint Venant partial differential equations, wich can be solved by mathematical models provided that the river bed geometric parameters and boundary conditions are known. In engeneering, the application of these models is restricted due to the high cost of the field work required to obtain the geometric parameters . In this dissertation, it is emonstrated that the rivers in the region between the Mar mountain range and Atlantic Ocean can be substituted by a very wide channel. This assumption simplifies the mathematical models, reduces the field work and may enable the practical application of these models
