The solution of this problem passes, invariably, for the development of mathematical models that, in their formulations, describe, in the closest way, the real scenery of the process. On the other hand, the mathematical manipulation of those models implies in the solution of nonlinear differential equations, as it is the case of Saint Venant's Equation, of great application in the studies of rivers, for gradually varied flow. This research uses a discretization, for the equations that governs the propagation of a flood wave, in natural rivers, with the objective of a better understanding of the propagation process. The results have shown that the hydraulic parameters play important game in the propagation of a flood wave.born digitalproceedings (reports)engCopyright and other restrictions may apply.
