How to use the Hydraulic Jump Calculator
- Fill in the values you know. Fields already contain typical example values that you can overwrite.
- Pick the unit for each measurement with the selector beside the field; changing a unit converts the number for you.
- Leave blank the value you want to find, or simply read the results panel, which updates as soon as there is enough information.
- A value the calculator worked out is shaded in its field. Type over it to switch which quantity is calculated.
If a value is missing or does not make sense, the field shows a short message explaining what to fix.
Formulas used
This calculator is built on the following relationships between its quantities. Each one can be solved for any of the values it contains, which is why you can leave any single field empty and have it calculated from the others:
discharge = v1 × y1 × B
discharge = v2 × y2 × B
F1 = v1 / (g×y1)^0.5
F2 = v2 / (g×y2)^0.5
depth_ratio = y2/y1
depth_ratio = 0.5× ((1+8×F1^2 )^0.5 - 1)
The calculator uses 4 further relationships to link its other values.

Frequently asked questions
What is a Hydraulic Jump?
A hydraulic jump occurs when there is a sudden change in flow depth and velocity in an open channel, typically transitioning from supercritical to subcritical flow. This phenomenon is crucial for energy dissipation in hydraulic structures.
How does a Hydraulic Jump Calculator work?
A Hydraulic Jump Calculator uses fluid mechanics principles to calculate various parameters such as flow rate, jump height, and energy loss. By inputting the flow depth before the jump and the velocity, the tool can output the downstream depth, energy dissipated, and other relevant metrics.
What parameters do I need to use the calculator?
To effectively use a Hydraulic Jump Calculator, you typically need the following parameters: the upstream flow depth (h1), the upstream velocity of the flow (v1), and the gravitational acceleration (g). Some calculators may also allow for additional parameters such as channel width.
Why is it important to calculate a hydraulic jump?
Calculating a hydraulic jump is vital for the design of hydraulic structures, helping engineers ensure sufficient energy dissipation and preventing erosion downstream. Accurate calculations help optimize the efficiency of systems like spillways, weirs, and other irrigation or drainage structures.
Are there different types of hydraulic jumps?
Yes, there are generally two types of hydraulic jumps: oscillating jumps and steady jumps. The oscillating jump has fluctuating depths, while the steady jump maintains a consistent height and flow rate once established. Understanding these types can influence design decisions.
