← GeographyWhich outcome results when a meandering stream's outer bank experiences persistent erosion due to shifts in groundwater flow?
A)Increased suspended sediment concentration downstream✓
B)Decreased floodplain recharge occurrences nearby
C)Streambed armoring by larger cobbles
D)Downstream ecosystem stabilization via depositions
💡 Explanation
Increased suspended sediment occurs because enhanced bank erosion adds fine particles; higher groundwater table increases pore water pressure, promoting 'fluvial entrainment', thereby mobilizing sediment into the stream channel rather than floodplain filtration.
