Erosion Mechanisms Quiz

Water Erosion: Rainfall, runoff, and flooding cause soil detachment and transport
- Sheet Erosion: Uniform removal of soil layer by sheet flow
- Rill Erosion: Concentrated flow creates small channels, eroding soil
- Gully Erosion: Large channels form, causing significant soil loss
Wind Erosion: Wind detaches and transports soil particles
- Deflation: Wind removes loose particles, creating depressions
- Saltation: Soil particles bounce and skip along the surface
Glacial Erosion: Glaciers scrape and transport rocks and soil

Sediment Sources: Eroded soil, rock, and organic matter
Transport Mechanisms:
- Suspension: Fine particles carried in water
- Bed Load: Coarse particles dragged along the bed
- Wash Load: Fine particles carried in surface runoff
Deposition: Sediment settles in new locations, forming deposits

Structural Controls:
- Check Dams: Reduce runoff velocity and sediment transport
- Sedimentation Ponds: Capture and settle sediment
- Gabions: Rock-filled cages to stabilize slopes
Vegetation Controls:
- Revegetation: Planting native species to stabilize soil
- Mulching: Covering soil with organic material to reduce erosion
Management Practices:
- Conservation Tillage: Reduces soil disturbance and promotes soil cover
- Cover Crops: Planting crops to protect soil between cash crops

Water Pollution: Sediment and pollutants in water bodies
Habitat Disruption: Altered ecosystems and loss of biodiversity
Infrastructure Damage: Sedimentation and erosion damage to infrastructure
Soil Degradation: Loss of fertile topsoil and reduced agricultural productivity

Site Assessment: Identify erosion and sedimentation risks
Erosion and Sediment Control Plans: Develop and implement site-specific plans
Regular Monitoring: Inspect and maintain control measures
Employee Training: Educate workers on erosion and sediment control
Continuous Improvement: Review and adapt BMPs based on performance

Water erosion occurs through rainfall, runoff, and flooding, causing soil detachment and transport
Sheet erosion involves uniform removal of a soil layer by sheet flow
Rill erosion occurs when concentrated flow creates small channels, eroding soil
Gully erosion forms large channels, causing significant soil loss
Wind erosion detaches and transports soil particles through deflation and saltation
Glacial erosion involves glaciers scraping and transporting rocks and soil

Water pollution occurs when sediment and pollutants enter water bodies
Habitat disruption alters ecosystems and leads to loss of biodiversity
Infrastructure damage occurs due to sedimentation and erosion
Soil degradation results in loss of fertile topsoil and reduced agricultural productivity

Site assessment identifies erosion and sedimentation risks
Erosion and sediment control plans are developed and implemented for specific sites
Regular monitoring involves inspecting and maintaining control measures
Employee training educates workers on erosion and sediment control
Continuous improvement involves reviewing and adapting BMPs based on performance
