Which risk increases significantly when intense rainfall saturates loess deposits?

💡 Explanation

Earthflows become dangerous because saturation reduces internal friction increasing shear stress, causing slope failure, a process labelled liquefaction; therefore, widespread and catastrophic earthflow events are likely rather than slower sediment deposition on river beds.
