Resumo
The aim of this research was to obtain the line flow profile as affected by a weir installed on a natural channel. The channel flow was measured through a suppressed weir. ln orderto obtain the channel geometric parameters a profile cross section survey was performed at severa! points, adjusting equations of the power type to descnbe the top width and the flow area as a function of depth. To obtain the line flow, the numeric solution ofBemoulli equation was used through the finite differences technique. The line flow profile was similar to that obSCIVed in the field, suggesting the adequacy of the proposed methodology.
