Which risk is amplified when pre-Columbian terrace drainage fails?

💡 Explanation

Increased soil moisture from failed terrace drainage causes hydrostatic pressure, triggering slope instability via soil swelling, because the clay content expands. Therefore, landslides become imminent rather than just runoff, salinity, carbon loss.
