Along an alluvial river, which outcome results due to bank undercutting?

💡 Explanation

Meander bends form and migrate because lateral erosion causes a positive feedback known as “bankfull discharge”, therefore the river shifts course rather than becoming stabilized. Delta formation relates to deposition, and groundwater relates to grain-sizes.
