Erosion Control: The Complete Walkthrough
This guide covers erosion control, rated a moderate task, typically taking days–weeks.
Erosion Control is a genuinely useful skill for most homesteads. Here's the complete picture behind our one-page printable guide.
Slow the water, hold the soil
Most erosion control comes down to two principles: slowing water down before it gains erosive speed, and keeping soil covered and rooted so it isn't exposed to direct rain and runoff impact in the first place.
Getting Set Up
Keep these points in mind:
- Ground cover plants or mulch for exposed soil
- Contour banks, swales, or check dams for concentrated water flow paths
- Deep-rooted vegetation for slope and waterway stabilisation
- An understanding of water flow patterns across your specific site
Step by Step
Worth paying attention to:
- 1. Observe and map where water concentrates and gains speed across your property, particularly after heavy rain.
- 2. Keep vulnerable soil covered — bare, exposed soil is dramatically more erosion-prone than vegetated or mulched ground.
- 3. Slow concentrated flow with contour banks, swales, or small check dams in gully lines.
- 4. Establish deep-rooted vegetation on slopes and along waterway banks specifically for stabilisation.
- 5. Monitor after significant rain events and address new erosion promptly, before it worsens.
Troubleshooting
Keep these points in mind:
- Erosion continuing despite planting — vegetation alone may be insufficient for actively concentrated, fast-moving water; may need structural intervention (banks, check dams) as well.
- New gullies forming — indicates a concentrated flow path that needs addressing at the source, not just downstream.
- Bank erosion along a waterway — often needs specific bank-stabilising vegetation and possibly structural work; may also require approval if the waterway is regulated.
- Uncertain about the right approach for a specific site — erosion control is quite site-specific; local landcare groups or agricultural extension services often provide valuable, locally-informed guidance.
Keeping It Going
Best time — establish erosion control measures before the wet season, when problems are most likely to develop or worsen. Duration — vegetation-based measures take a season or more to establish; structural measures are effective immediately but need vegetation to become fully stable long-term. Maintenance — regular monitoring after rain events, with prompt attention to any new erosion. Signs of success — stable, vegetated soil that isn't visibly moving or forming new channels after rain events.
