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 Gaylord, the porosity for the standing corn was **0.50**.
Assuming the corn height to be 6.5 ft (1.98 m), the
snow storage capacity was 38.2 t/m for each 8-row strip.
Therefore, for the two strips, the total Q_{c}
is approximately **76.4 t/m.**
