Step Rationales for Every Answer – Pass the
CPESC Certification on Your First Attempt
Erosion - correct answer,,,,process in which, by the actions
of wind and/or water, soil particles detached and
transported
Sediment - correct answer,,,,eroded material suspended in
wind or water
Sedimentation - correct answer,,,,deposition of eroded
material
Types of Erosion - correct answer,,,,splash
sheet
rill
,gully
channel
Splash erosion - correct answer,,,,raindrop impact energy is
enough to dislodge surface sediments
sheet erosion - correct 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
Rill Erosion - correct answer,,,,as flow concentrates, small
channels begin to form in the soil surface
Gully Erosion - correct answer,,,,Formed when runoff cuts
rills deeper and wider or when flows from several rills
come together and form a large channels
Channel Erosion - correct answer,,,,may become unstable
due to increased flows or changes in upstream sediment
load
,Natural erosion - correct answer,,,,generally considered
due to the influences of climate on the surface of the earth
Accelerated erosion - correct answer,,,,natural erosion plus
human activities
What problems can accelerated erosion cause? - correct
answer,,,,Unrestricted development
removal of surface cover
increased imperviousness
poor stewardship
Problems associated with construction related erosion -
correct answer,,,,problems for down slope property owners
nuisance problems on streets
clog streams and storm drains
increased turbidity downstream
cover sensitive habitat with sediment
, Identify instream damages of sediment - correct
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
Suspended material - correct answer,,,,sediment can affect
light penetration, channel stability, fisheries and habitat
Name Off stream damages - correct answer,,,,Increased
flood hazards
increased water treatment costs
decreased capacity in conveyance facilities
higher infrastructure maintenance costs
