Which mechanical consequence occurs when terrace wall erosion exceeds hydraulic capacity during intensive, ancient hillside farming?

💡 Explanation

Increased downstream sediment deposition results from terrace wall failure by soil erosion; Slope instability causes downhill sediment transport into waterways, because the barrier failed. This sedimentation overwhelms natural fluvial filtering, rather than chemical- or bio- changes alone influencing soil conditions.
