Gradient

The slope,or change in elevation,of land or improvements such as a pipe or a road.It is expressed as the ratio of inches (or feet) of rise or fall over a specified distance. It is similar to the concept of pitch in roofing.Figure A (above) has a gradient of 1:12 because the grade increases by 1 foot over a distance of 12 feet. Figure B has a gradient of 1:6.
