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 problems for down slope property owners
construction related erosion nuisance problems on streets
clog streams and storm drains
increased turbidity downstream
cover sensitive habitat with sediment
Identify instream damages of destruction of spawning areas, food sources,
sediment 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?
priority pollutants include nutrients
pathogens
heavy metals
toxics
sediment
salts
detergents
hydro carbons
Clean Water Act (CWA) 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
Section 401 water quality certification
requires applicant, including any construction or
operation of a facility, to obtain certification to
discharge ANY pollutant.
