Shoving is measured by determining the area in square feet (square meters) of the swell caused by shoving.
|
Severity |
Height Differential |
|
L |

|
H |
>1 ½ in. (>40 mm) |
As a guide, the above table may be used to determine the severity levels of shoving. At the present time, no significant research has been conducted to quantify levels of severity of shoving.
