    • How do you calculate watershed runoff?

      Measure the length and width of the site for which you want to calculate surface runoff. Note the length and width in feet. Calculate the area of the site in square feet by multiplying the length times the width. Look up the average rainfall per year for your proposed site. Convert this data from inches to feet by dividing it by 12.
