Your Erosion Prevention Plan
Imagine you are an engineer hired to prevent erosion on a bare hillside. You proved that plants help, but what else can you try?
Test these prevention methods on your bare soil hill:
- Grass/plants (already tested)
- Mulch (wood chips or shredded paper covering the soil)
- Small rocks/gravel on the surface
- Terraces (small flat steps cut into the hill)
- A small wall at the bottom (retaining wall)
Which method will prevent the most erosion? Predict, then test!
