1. Erosion - ANSWER ✓ process in which, by the actions of wind and/or water,
soil particles detached and transported
2. Sediment - ANSWER ✓ eroded material suspended in wind or water
3. Sedimentation - ANSWER ✓ deposition of eroded material
4. Types of Erosion - ANSWER ✓ splash
sheet
rill
gully
, channel
5. Splash erosion - ANSWER ✓ raindrop impact energy is enough to dislodge
surface sediments
6. sheet erosion - ANSWER ✓ caused by rain splash detaching soil particles
lifting them up and removing them by shallow "sheets" of water flowing down
the sloped soil surface
7. Rill Erosion - ANSWER ✓ as flow concentrates, small channels begin to form
in the soil surface
8. Gully Erosion - ANSWER ✓ Formed when runoff cuts rills deeper and wider
or when flows from several rills come together and form a large channels
9. Channel Erosion - ANSWER ✓ may become unstable due to increased flows or
changes in upstream sediment load
10. Natural erosion - ANSWER ✓ generally considered due to the influences of
climate on the surface of the earth
11. Accelerated erosion - ANSWER ✓ natural erosion plus human activities
,12. What problems can accelerated erosion cause? - ANSWER ✓ Unrestricted
development
removal of surface cover
increased imperviousness
poor stewardship
13. Problems associated with construction related erosion - ANSWER ✓ problems
for down slope property owners
nuisance problems on streets
clog streams and storm drains
increased turbidity downstream
cover sensitive habitat with sediment
14. Identify instream damages of sediment - ANSWER ✓ destruction of spawning
areas, food sources, habitat
direct toxicity to wildlife
lake degradation
filling of navigation channels
impacts to commercial fisheries
reduction of water storage capacities
, 15. Suspended material - ANSWER ✓ sediment can affect light penetration,
channel stability, fisheries and habitat
16. Name Off stream damages - ANSWER ✓ Increased flood hazards
increased water treatment costs
decreased capacity in conveyance facilities
higher infrastructure maintenance costs
17. What has increased the amount of impervious surface in our watersheds? -
ANSWER ✓ Urbanization and development
18. priority pollutants include - ANSWER ✓ nutrients
pathogens
heavy metals
toxics
sediment
salts
detergents
hydro carbons
