F = 3.247 \cdot W \cdot H^{1.48} - \frac{0.566 \cdot W^{1.9}}{1 + 2 \cdot W^{1.8}} \cdot H^{1.9} + 0.609 \cdot H^{2.5}

$F = 3.247*W*H^1.48-(0.566*W^1.9)/(1+2*W^1.8)*H^1.9+0.609*H^2.5$

The Cipolletti Weir Flow Rate Calculator computes the rate at which water flows from a Cipolletti Weir given the width of the base of the weir and the height of the water level.

INSTRUCTIONS: Enter the following

(W) Width of the base of the weir
(H) Height of the water level above the base

Flow Rate (F): The flow rate of the water is returned in cubic feet per second

Type of snow or ice	(kg/m³)
Fresh New snow	50-70
Damp new snow	100-200
Settled snow	200-300
Depth hoar	100-300
Wind packed snow	350-400
Firn (granular)	400-830
Very wet	700-800
Glacier ice	830-917
Rain/Melt	997
