Downstream water diversion from meandering rivers causes which effect?

A)Increased oxbow lake formation rate
B)Decreased point bar sediment thickness
C)Higher channel sinuosity downstream length
D)Increased floodplain erosion river level

💡 Explanation

Reduced flow causes increased Sediment Deposition and therefore increased meander cutoff rate, accelerating oxbow lake creation because decreased flow allows sediment accumulation rather than continued channel erosion.
