摘要：

In this paper, the outflow process of a triangular broad-crested device is examined using the dimensional analysis and the incomplete self-similarity theory. A new theoretical stage-discharge relationship is proposed, and its applicability is verified using measurements available in literature.The proposed power equation is characterized by a coefficient depending on device apex angle and a constant value of the exponent.
