    ABSTRACTConsider the following scenario: A channel with horizontal longitudinal slope, without friction effects, where there is

    no structure in some section of the control volum. and Coriolis and Boussines coefficient eual to one. !nder these

    conditions can produce a hydraulic jump where the specific strength is maintained constant before and after this

    phenomenon is present in the flow. "ccurs when a supercritical flow changes by any condition imposed from a rapid

    change to a slow rate regime #subcritical$, generating a relatively abrupt jump in the water surface at the e%pense of

    the flow of their energy dissipates.
