2026 | 100% Pass Guarantee
1. In a construction project on a site with both convex and concave slopes, what
erosion control measures should be prioritized to minimize soil loss?
Implement measures on convex slopes to slow down water flow and
reduce erosion.
Use the same measures on both types of slopes without
differentiation.
Focus solely on concave slopes since they naturally reduce erosion.
Increase vegetation cover only on flat areas to prevent erosion.
2. Describe the significance of temporarily seeding dormant stockpiles in the
context of erosion control at construction sites.
Temporarily seeding dormant stockpiles has no impact on erosion
control.
Temporarily seeding dormant stockpiles is only necessary during
heavy rainfall.
Temporarily seeding dormant stockpiles increases soil compaction.
Temporarily seeding dormant stockpiles helps prevent soil erosion
and sediment runoff.
3. In the Universal Soil-Loss equation (USLE), the K factor describes the soils __
Cover and management at the site
Potassium concentration
Erodibility
Slope length
, Rainfall intensity at the site
4. What does soil erodibility measure?
The moisture retention capacity of soil
Susceptibility of soil to erosion
The pH level of the soil
The amount of organic matter in soil
5. Which soil property identifies how erodible the soil (inherent susceptibility to
water erosion) is?
SAR
K factor
ET factor
T value
6. Who administers the Erosion and Sediment Control and Stormwater
Management programs in Virginia?
Virginia Department of Environmental Quality
Department of Transportation
Local municipalities
Environmental Protection Agency
7. Describe the significance of the gully stage in the context of soil erosion and
its impact on construction sites.
The gully stage is the initial phase of erosion with minimal impact.
, The gully stage indicates severe erosion that can lead to significant
land degradation and may necessitate heavy machinery for
remediation.
The gully stage is primarily caused by wind rather than water.
The gully stage is easily managed with simple landscaping techniques.
8. What is the percentage of total erosion that is caused by accelerated erosion
due to land disturbance activities?
30%
70%
50%
90%
9. Describe the role of geologic erosion in the overall erosion process as
outlined by the Virginia Department of Environmental Quality.
Geologic erosion accounts for 30% of total erosion, indicating its
significant role in the erosion process.
Geologic erosion has no impact on total erosion.
Geologic erosion only occurs in specific regions.
Geologic erosion is the primary cause of all erosion types.
10. Describe the role of NPDES in relation to water quality management.
NPDES regulates discharges of pollutants into U.S. waters to
protect water quality.
NPDES monitors air quality in urban areas.
NPDES is a certification program for environmental engineers.
, NPDES provides funding for water treatment facilities across the U.S.
11. If a construction site fails to seed dormant stockpiles within the required 14
days, what potential consequences could arise regarding erosion and
sediment control?
Enhanced growth of vegetation in the area.
No significant impact on erosion control measures.
Increased soil erosion and sediment runoff into nearby water
bodies.
Improved soil stability and reduced erosion.
12. In a construction site located in a windy area, which erosive force should be
prioritized in the erosion control plan?
Ice erosion
Gravity erosion
Wind erosion
Water erosion
13. What is the effect of a steeper slope in a watershed?
decreased water speed, increased erosion
increased water speed, decreased erosion
increased water speed, increased erosion
decreased water speed, decreased erosion
14. What type of pollution is stormwater runoff classified as when it is not
concentrated?
Chemical runoff
