Webb30 juli 2003 · The theory of viscous hydraulic jumps (Watson 1964) is extended through inclusion of the curvature force, and yields a new prediction for the radius of circular hydraulic jumps. WebbHunter Rouse’s primary contribution was the application of ﬂ uid-mechanics theory, illuminated and validated by laboratory experimentation, to hydraulics. His hydraulics work put hydraulic engineering on a more rational plane than it had previously occupied. Rouse championed the application of ﬂ uid mechanics to hydraulic engineering in many ways.
