Soil slope
Soil slope is particularly important in terms of its effect on erosion. Slope can be measured in

Measuring soil slope
Use a protractor (figure at left) as a simple method for slope estimation (U Minnesota)
Convert slope to degrees
To covert percent slope to slope in degrees:
"Angle in degrees" = cotangent (percent slope/100) = cotangent (Rise / Run) Percent slope = tangent (percent slope/100)
