Terms in this set (298)
Erosion process in which, by the actions of wind and/or water,
soil particles detached and transported
Sediment eroded material suspended in wind or water
Sedimentation deposition of eroded material
,Types of Erosion splash
sheet
rill
gully
channel
Splash erosion raindrop impact energy is enough to dislodge surface
sediments
sheet erosion caused by rain splash detaching soil particles lifting
them up and removing them by shallow "sheets" of
water flowing down the sloped soil surface
Rill Erosion as flow concentrates, small channels begin to form in
the soil surface
Gully Erosion Formed when runoff cuts rills deeper and wider or
when flows from several rills come together and form
a large channels
Channel Erosion may become unstable due to increased flows or
changes in upstream sediment load
Natural erosion generally considered due to the influences of climate
on the surface of the earth
Accelerated erosion natural erosion plus human activities
What problems can accelerated Unrestricted development
erosion cause? removal of surface cover
increased imperviousness
poor stewardship
, Problems associated with construction problems for down slope property owners
related erosion nuisance problems on streets
clog streams and storm drains
increased turbidity downstream
cover sensitive habitat with sediment
Identify instream damages of sediment 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
Suspended material sediment can affect light penetration, channel stability,
fisheries and habitat
Name Off stream damages Increased flood hazards
increased water treatment costs
decreased capacity in conveyance facilities
higher infrastructure maintenance costs
What has increased the amount of Urbanization and development
impervious surface in our watersheds?
