Abstract The name of Jean-Baptiste Bélanger is often linked with the Bélanger equation and the application of the momentum principle to the hydraulic jump. A study of his 1828 treaty shows that the manuscript was focused on the study of gradually varied open channel flows, with the development of the backwater equation. Jean-Baptiste Bélanger’s development was remarkable by its lucidity and cleverness, which yielded some very accurate results. He further discussed the singularity of the backwater equation, and introduced the concept of critical flow conditions, many decades before contemporary scientists. On the other hand, and although he incorrectly applied the energy principle to the hydraulic jump, his equation for a hydraulic jump in a rectangular horizontal channel was improper. The Bélanger equation was derived ten years later.
