Why is sediment control and erosion prevention important? ANSWER: Storm
water runoff is the main source of water impairment in South Carolina. It is
required by law to protect aquatic habitats and downstream surface water.
What is erosion? - ANSWER The process through which gravity, wind, water,
and ice wear away the land surface
Another name for natural erosion is ____________. ANSWER Erosion of the
geology
How quickly does geologic or natural erosion occur? - ANSWER Rather slow
Where is the quickest rate of natural erosion? - ANSWER Along coastlines and
the paths of streams
To what extent does natural erosion account for the degraded sediment?
ANSWER 30%
Describe increased erosion. - ANSWER higher levels of erosion brought on by
human activities
Which factors are the main causes of rapid erosion? - ANSWER Construction,
farming, and collecting timber
What proportion of eroded sediment results from faster erosion? 70%
ANSWER
What is the anticipated annual rate of erosion of forest land, expressed in tonnes
per acre? - A ANSWER of 1 or higher
How many tonnes per acre per year is the anticipated rate of erosion on
farmland? ANSWER 15 or above
