CORRECT ANSWER-2008
Total Maximum Daily Load (TMDL) - CORRECT ANSWER-The maximum
amount of a pollutant allowed to enter a waterbody so that the waterbody will
meet and continue to meet water quality standards.
Factors that influence erosion (6) - CORRECT ANSWER-Rainfall Characteristics
Soil Erodibility
Topography
Climate
Vegetative Cover
Season
Components of a SWPPP (4) - CORRECT ANSWER-Site Evaluation
Practice and Plan Design
Certification/ Notification
Implementation
List the soil types in order of most erodible to least erodible. - CORRECT
ANSWER-Silt
Sand
Clay
Gravel
Erosion Rate - CORRECT ANSWER-The rate of wearing away of natural
surfaces by external forces.
, Sediment Yield - CORRECT ANSWER-The amount of sediment reaching or
passing a point of interest in a given period of time.
Gross erosion = - CORRECT ANSWER-Sheet erosion + rill erosion + other
erosion
What does RUSLE Stand for? - CORRECT ANSWER-Revised Universal Soil
Loss Equation
What is the RUSLE Equation? - CORRECT ANSWER-A = R x K x (LS) x C x P
Units for the RUSLE Equation - CORRECT ANSWER-ton/acre/year
A (From RUSLE) - CORRECT ANSWER-Soil loss in ton/acre/year
R (From RUSLE) - CORRECT ANSWER-Rainfall runoff erosivity factor
K (From RUSLE) - CORRECT ANSWER-Soil erodibility factor
L (From RUSLE) - CORRECT ANSWER-Slope length factor
S (From RUSLE) - CORRECT ANSWER-Slope steepness factor
C (From RUSLE) - CORRECT ANSWER-Cover management factor
P (From RUSLE) - CORRECT ANSWER-Support practice factor
If P and C are not given for RUSLE, what numerical factor is to be used? -
CORRECT ANSWER-1
What does MUSLE Stand for? - CORRECT ANSWER-Modified universal soil
loss equation
When would you use the MUSLE Equation compared the the RUSLE equation? -
CORRECT ANSWER-The RUSLE equation is based off more general storm
events, where MUSLE is meant for a specific storm event.
