||BRANDNEW!!!||
When are outlet protectors used? Examples? - ANSWER-To
control runoff; wattles, check dams (energy dissipaters) or
thick/matted veg, riprap (ground cover)
What is the RUSLE equation? - ANSWER-A = R K L S C P
What are the units for A in RUSLE? - ANSWER-Ton/ha/year
What kind of erosion does RUSLE cover? - ANSWER-Sheet and
rill erosion only
Define soil erodibility - ANSWER-The ease with which soil is
detached by splash during rainfall
Why is sediment yield different from erosion rate? - ANSWER-
Sediment yield is the amount of eroded soil that is delivered to a

certain point whereas erosion rate is the rate of soil wearing away
from an area
What is the formula for MUSLE? - ANSWER-T=11.8(V.Qp)^0.56 K
LS C P
What is V and Qp in MUSLE? - ANSWER-V = volume of storm
runoff in mm3
Qp = Peak flow for storm in m3/s
How many;
mm in 1 m?
m in 1 km?
m2 in 1 ha?
kg in 1 tonne? - ANSWER-1,000 mm in 1m

What are the types of wind erosion? - ANSWER-Surface creep;
heavy particles rolling around surface
Saltation; particles lifted into air and quickly fall (most
common...think dust behind vehicle)
Suspension; particles lifted into air and transported away
What factors affect soil loss from wind erosion? - ANSWER-
Compaction, soil moisture, cover, wind speed
What are some ways to form a less erodible surface from wind? -
ANSWER-Increase soil moisture (water trucks), chemical binders,
and vegetation (best one)
How can you reduce surface wind speed? - ANSWER-Surface
cover (vegetation, plastic), orientation of surface (stockpiles
perpendicular to wind), windscreen (hedge rows)
Define hydrology - ANSWER-The study of the movement,
distribution and quality of surface water
