Which outcome occurs when a cutoff develops within meandering river bend?

A)Oxbow lake formation within floodplain
B)Increased streamflow channel sinuosity
C)Braided channel development region-wide
D)Decreased sediment deposition in delta

💡 Explanation

An oxbow lake results from channel avulsion. River avulsion occurs because continued erosion and deposition causes the river to bypass a meander loop via a cutoff; therefore an oxbow lake forms, rather than the unaltered river flow.
