← GeographyWhich mechanism promotes increased discharge in alluvial river systems?
A)Vegetation-driven evapotranspiration reduction✓
B)Decreased sediment supply from tributaries
C)Floodplain sediment infiltration increase
D)Decreasing river channel sinuosity
💡 Explanation
Reduced evapotranspiration resulting from deforestation causes increased channel discharge because less water gets transferred to the atmosphere, therefore the total river volume expands, rather than getting adsorbed or reduced by vegetation water consumption.
