Virginia Erosion and Sediment Control Inspector Exam
NEWEST ALL QUESTIONS AND VERIFIED SOLUTIONS
2026-2027 LATEST UPDATE THIS YEAR
QUESTION: What are 4 erosive forces? - ANSWER-wind
water
ice
gravity
QUESTION: Name and define 5 stages of soil erosion. - ANSWER-Raindrop- 90% of total soil
erosion
Sheet- the soils ability to infiltrate water is exceeded and it runs in sheet flow (about 100 ft
before concentrating), how sediment gets transported
Rill- when sheet flow begins to concentrate, velocity and turbulence increase, but easily
repaired
Gully-when rills converge, larger than rill and usually requires heavy equipment to repair
Channel- large volume of water increases the gully, vertical sides are observed or for an existing
streambed when structural integrity is destroyed

QUESTION: What are the factors of rainfall impact? - ANSWER-Kinetic energy is dependent on
rainfall amount/intensity, raindrop diameter, and raindrop velocity
QUESTION: What are two damaging effects of rainfall impact? - ANSWER-Causes soil
compression which reduces infiltration
Mainly occurs in May-Sept which is when disturbance is most active
QUESTION: 4 factors influencing erosion - ANSWER-climate
groundcover (influenced by humans)
soil properties
topography (influenced by humans)
Q; Erosion Impact Area - ANSWER-area of land NOT ASSOCIATED with a current land- disturbing
activity but contributing to sedimentation
QUESTION: How much more soil loss occurs from construction sites versus natural soil erosion
rates? Agricultural land? - ANSWER-1000 times more than the average natural soil erosion rate.
20 times more than agricultural land.
