length of hydraulic jump formula. Whereas there is not much investigation about the determining the roller length of a hydraulic jump we have done an experimental study to represent the formula to estimate the roller length. A qualitative comparison between some of these equations is shown in Figure 4 assuming the interval 2 Fr1 20 as valid for all equations.

A hydraulic jump is a phenomenon in the science of hydraulics which is frequently observed in open channel flow such as rivers and spillwaysWhen liquid at high velocity discharges into a zone of lower velocity a rather abrupt rise occurs in the liquid surface.
