Question:
Erosion.
Answer:
process in which, by the actions of wind and/or water, soil particles detached and transported
Question:
Sediment.
Answer:
eroded material suspended in wind or water
Question:
Sedimentation.
Answer:
deposition of eroded material
Question:
Types of Erosion.
Answer:
splash sheet rill gully channel
Question:
Splash erosion.
Answer:
,raindrop impact energy is enough to dislodge surface sediments
Question:
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
Question:
Rill Erosion.
Answer:
as flow concentrates, small channels begin to form in the soil surface
Question:
Gully Erosion.
Answer:
Formed when runoff cuts rills deeper and wider or when flows from several rills come together and
form a large channels
Question:
Channel Erosion.
Answer:
may become unstable due to increased flows or changes in upstream sediment load
Question:
Natural erosion.
Answer:
,generally considered due to the influences of climate on the surface of the earth
Question:
Accelerated erosion.
Answer:
natural erosion plus human activities
Question:
What problems can accelerated erosion cause?
Answer:
Unrestricted development removal of surface cover increased imperviousness poor stewardship
Question:
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
Question:
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
Question:
Suspended material.
Answer:
, sediment can affect light penetration, channel stability, fisheries and habitat
Question:
Name Off stream damages.
Answer:
Increased flood hazards increased water treatment costs decreased capacity in conveyance facilities
higher infrastructure maintenance costs
Question:
What has increased the amount of impervious surface in our watersheds?
Answer:
Urbanization and development
Question:
priority pollutants include.
Answer:
nutrients pathogens heavy metals toxics sediment salts detergents hydro carbons
Question:
Clean Water Act (CWA).
Answer:
Federal Water Pollution Control Act enacted to restore and maintain the chemical, physical and
biological integrity of the waters of the US administered by USEPA
