Which soil failure risk is MOST increased when rainfall intensity exceeds terraced field drainage capacity?

💡 Explanation

When rainfall exceeds drainage capacity on terraced fields, overland flow concentrates downhill because terraces are overwhelmed, resulting in increased shear stress on the topsoil. Therefore, widespread sheet erosion becomes the primary risk, rather than wall fracturing, increased leaching, or soil compaction, which require different conditions.
