Summary

The calculated onset parameter rises sharply as the layer becomes shallower at fixed extraction and density. Based on Cooper (2002), p. 3-228.

Original illustration for Plugholing, level 3 Advanced.

Source basis: Cooper (2002), p. 3-228; Milke (2002), p. 4-306 for illustrative 20 m³/s rate. Calculations in calculations/plugholing.py. Create an original visual; redraw, do not copy source figures.
Alt text: Curve showing a much larger Froude number for a 1.5 metre layer than for a 3 metre layer.
Accuracy notes: The threshold belongs to Cooper’s circular-vent formulation. Do not label this as a complete reservoir time-history prediction.
