← GeographyWhich mechanism amplifies stream meandering when deforestation occurs on riparian slopes?
A)Decreased sediment deposition rates
B)Increased channel flow velocity
C)Reduced bank vegetation reinforcement✓
D)Elevated groundwater discharge volume
💡 Explanation
When deforestation occurs, reduced bank vegetation reinforcement results because the roots no longer bind the soil, increasing bank erosion caused, leading to greater sediment influx to the stream. Therefore increased meandering results rather than altered deposition, increased velocity, or discharge which depend on different environmental factors.
