3 DAY SEMINAR AGENDA, One day class and two days field instruction

 Introduction: Overview and Course objectives

 Regulatory requirements

• Forest Practices Code
• Water Act

 Video "Soil erosion and sediment control" - International Erosion Control Association.

 Types of Erosion and Solutions to Erosion Problems

• Raindrop erosion
• Sheet erosion
• Rilling and Gully erosion
• Streambank erosion
• Mass movement
• Dry ravelling slopes

 Mass Slope Movement

• Deep seated failures
• Near surface slope movement
• Surface slides
• Rotational Slumps
• Piping Failures

 Factors Influencing Erosion

• Soil Types
• Rain intensity and duration
• Ratio of slope length and steepness
• Effect of Vegetation
• Surface irregularities and roughness

 Use of temporary sediment control devices

• Silt fences
• Hay Bales
• Filter Cloth
• Settling ponds
• Check dams
• Other commercial products

 Bio-engineering techniques

• Seeding - Dry and Hydroseeding - Seed mixtures - Natural species
• Planting of whips (live staking)
• Seedlings (Hardwoods and Conifers)
• Wattling and Wattle Fences
• Brush Layering methods
• Live Pole Drains
• Live Gully Breaks
• Live Silt Fences
• Live Bank Protection

 Combining Hard (Structural) Engineering with Bio-engineering

• Engineered Walls - Lockblock, Steel bin, Log, Gabions, Geogrid, Rock, Rip-rap
• French Drains

 Cut bank and steep slope stability problems

• Oversteepened
• Loss of toe support
• Overhangs
• Unstable Stumps and Rocks
• Piping

 Mature trees and slope stability

 Fertilization

 Calculation of soil loss

 Tools and Equipment

 Maintenance and monitoring
