- •
Experiments on size evolution of soil aggregates within a turbulent flow are analyzed
- •
Soil aggregates are subject to abrasion within the controlled turbulent flow
- •
Increasing suspended concentration enhances abrasion resulting in smaller particles
- •
Badland aggregates reduce to smaller particles than those resulting from a brown soil
