promulgated by the United States Natural Resources Conservation Service
Engineering Field Manual for Conservation Practices.

uniform loss across the exposed upper layer of the soil or shallow
irregular scouring of the soil surface.

percentage, which represents a relatively homogeneous surface incline
or decline over the area disturbed.
SOIL LOSS RATE
The rate, usually measured in tons per acre per year, at
which soil is transported beyond the perimeter of a given control
site and which occurs as a result of sheet and rill erosion. This
term does not apply to soil movement resulting from concentrated flow
such as gully or bank erosion.
STORM EVENTS
The precipitation amounts that occur over a twenty-four-hour
period that have a specified recurrence interval for Dane County,
Wisconsin. For example, one-, two-, ten- and one-hundred-year storm

permanently or temporarily attached to, placed upon, or set into the
ground, streambed or lake bed.
UNNECESSARY HARDSHIP
