The table to the right gives
the porosity fraction for various snow fences and the
resulting snow storage capacity (Q_{c}). Q_{c}
is calculated using the formula on the right.

For the case study
at Lamberton, the porosity for the twin-row planting
of honeysuckle was **0.70**. Assuming the honeysuckle
height to be 6.5 ft (1.98 m), the snow storage capacity
was **30.5 t/m.**
