Which outcome increases because water accumulates beyond designed capacity in Inca agricultural terracing?

💡 Explanation

Increased water saturation amplifies downslope hydraulic pressure via the mechanism of pore water pressure. This creates instability because the added weight reduces soil shear strength, therefore slope failure increases as saturation rises, rather than minimizing soil erosion.
