    Horizontal open channel flow. Hydraulic jump calculation

    Bimr, Thank you for that info. I am already aware of the different type of approximation GVF and RVF. But do you think it is possible to calculate a estimation of the end of the GVF zone. The pink curve in my original post was calculated using GVF assumptions and intigrating the backwater...

    Horizontal open channel flow. Hydraulic jump calculation

    Hello bimr, Thank you for the very usefull links u provided. I know that there is a way to calculate the length of the jump itself. But what i need is an estimation of the location of the start of the jump. I have taken a look into the VBA Excell sheet (second link you provided). It depicts...

    Horizontal open channel flow. Hydraulic jump calculation

    Dear Fellow Engineers I'm having an issues with my calculations. This case concerns a open channel flow that start off being supercritical on the left and turns into subcritical flow after a hydraulic jump. Given: Volume flow rate Q = 0.16m^3/s Width of the channel b = 1m Resulting...
