During intense El Niño events, which outcome relating to river sediment occurs?

💡 Explanation

El Niños increase precipitation and therefore river discharge, leading to greater sediment transport; the Abrupt Climate Change theory links this process to Catastrophic Megafloods depositing extra river sediment as increased coastal loess because increased erosion supplies the material, rather than decreasing oxbows.

• Which mechanism causes fertile plains formation from loess?
• Which event strongly promotes accelerated karst topography development?
• Which risk increases when anoxic conditions spread to fjord sediments?
• Which risk escalates dramatically where loess deposits form thick, unconsolidated layers?
• Which horizon development occurs when regolith weathering increases?
• Which process increases when glacial meltwater stream volume increases?
