Which outcome results when poorly designed terraces overload the supporting soil, due to prolonged saturation after periods of heavy rainfall?

💡 Explanation

Soil liquefaction risk increases during extreme water saturation events because pore water pressure increases dramatically via the mechanism of effective stress reduction. Therefore, the strength of supporting soil greatly decreases, rather than uniformly distributing enhanced nutrients under normal drainage conditions.
