Erosion Impact Area - 🧠ANSWER ✔✔area of land NOT ASSOCIATED with
a current land- disturbing activity but contributing to sedimentation
How much more soil loss occurs from construction sites versus natural soil
erosion rates? Agricultural land? - 🧠ANSWER ✔✔1000 times more than the
average natural soil erosion rate.
20 times more than agricultural land.
What are 4 erosive forces? - 🧠ANSWER ✔✔wind
water
ice
gravity
, Name and define 5 stages of soil erosion. - 🧠ANSWER ✔✔Raindrop- 90%
of total soil erosion
Sheet- the soils ability to infiltrate water is exceeded and it runs in sheet
flow (about 100 ft before concentrating), how sediment gets transported
Rill- when sheet flow begins to concentrate, velocity and turbulence
increase, but easily repaired
Gully-when rills converge, larger than rill and usually requires heavy
equipment to repair
Channel- large volume of water increases the gully, vertical sides are
observed or for an existing streambed when structural integrity is destroyed
What are the factors of rainfall impact? - 🧠ANSWER ✔✔Kinetic energy is
dependent on rainfall amount/intensity, raindrop diameter, and raindrop
velocity
What are two damaging effects of rainfall impact? - 🧠ANSWER ✔✔Causes
soil compression which reduces infiltration
Mainly occurs in May-Sept which is when disturbance is most active
4 factors influencing erosion - 🧠ANSWER ✔✔climate
