: Covers steady gradually varied flow (GVF), its differential equations, and the hydraulics of hydraulic jumps.
Open-channel flow is the motion of a liquid with a free surface exposed to the atmosphere—common in rivers, canals, drainage channels, and spillways. This essay explains core concepts, governing equations, flow classifications, energy and momentum principles, analytical methods, and practical design considerations. Where relevant, I note how these apply to typical hydraulic engineering studies such as those by practitioners like Madan Mohan Das (assumed author/researcher in hydraulics). open channel flow madan mohan das pdf work
