← GeographyWhich geomorphological effect accelerates when a river breaches the neck of a meander bend?
A)Increased sediment deposition in levees
B)Rapid formation of an oxbow lake✓
C)Decreased floodplain soil fertility
D)Widespread salt water intrusion
💡 Explanation
When a river breaches a meander neck during high flow events, channel straightening occurs because the steeper gradient favors flow through the new channel, cutting off the meander loop. Therefore rapid formation of an oxbow lake results, rather than levee deposition, soil infertility or saltwater intrusion, all of which depend on different conditions.
