Which consequence results when fluvial levees fail under lateral stress?

💡 Explanation

When a levee fails during lateral erosion, the river can suddenly jump its banks; this process is called avulsion pushing flow rapidly to a new adjacent course, because this involves abrupt channel migration rather than plume spreading, or base level effects.

• Which consequence results when increased sediment load exceeds capacity?
• Which outcome occurs when infiltrating acidic groundwater reaches caves?
• Which characteristic determines the settling rate of alluvial sediments as river flow decreases?
• Which outcome diminishes dune migration rate when vegetation emerges?
• Which outcome occurs when high sediment input overwhelms fluvial transport capacity on a low-gradient plain?
• Which outcome occurs when increased glacial melt impacts gyre formation?
