Which outcome typically results when loess deposits undergo compaction?

💡 Explanation

Slope instability occurs because compaction increases density and reduces cohesion, which decreases friction and shear strength through grain rearrangement; therefore slope failure risk rises with loess compaction rather than enhanced infiltration, due to a lower porosity structure.
