CPESC Erosion Prediction (RUSLE and
MUSLE) Questions and Answers Graded A+
The "A" value obtained using RUSLE can be multiplied by an "M" value to determine
____________________? soil loss for a portion of a year.
In general wind erosion begins at speeds of approximately _________? 13 mph
What are the 3 types of soil erosion? Suspension
Saltation
Surface creep
Which method of wind erosion accounts for over half of soil movement? Saltation
What size particles move by suspension? <0.05mm
What size particles move by saltation? 0.05 - 0.5mm
, What size particles move by surface creep? >0.5mm
Practices used to minimize wind erosion? ridging
turning over the soil to increase cloddiness
irrigation to increase cohesiveness
growing vegetation
Methods to prevent wind erosion on storage piles? covering the pile
erecting a windscreen
changing pile orientation
spraying water on the pile
applying a chemical dust suppressant
What is sediment yield the amount of eroded soil that is delivered to a point in the
watershed that is remote from the origin of the detached soil particles
Sediment yield does not include _______________? the sediment that is deposited after it
is eroded but before it reaches the point of interest in the watershed.
