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. In order to obtain the channel geometric parameters a profile cross section survey was performed at several points, adjusting equations of the power type to describe the top width and the flow area as a function of depth. To obtain the line flow, the numeric solution of Bernoulli equation was used through the finite differences technique. The line flow profile was similar to that observed in the field, suggesting the adequacy of the proposed methodology. KEY-WORDS: Open channel; gradually varied flow; backwater curve.

O presente trabalho teve como objetivo a obtenção do perfil da linha d’água do remanso provocado pela instalação de um vertedor em um canal natural. A vazão do canal foi medida por um vertedor sem contração lateral instalado no canal utilizado neste estudo. Para a obtenção dos parâmetros geométricos do canal, procedeu-se ao levantamento do perfil da sua seção transversal em vários pontos. Com os dados obtidos, ajustaram-se as equações do tipo potencial para descrever a largura do espelho d’água e a área molhada em função da profundidade. Para a obtenção do perfil da linha d’água, empregou-se a solução numérica da equação de Bernoulli pela técnica das diferenças finitas. O perfil da linha d’água simulado aproximou-se do observado no campo, o que confere adequação à metodologia proposta neste trabalho.
