Which effect results when an alluvial river's sediment load increases rapidly due to deforestation upstream?

💡 Explanation

When sediment load increases rapidly, aggradation occurs because the river's capacity to transport sediment is exceeded, raising the channel bed, and thus promoting new channels to form intertwined; a braided pattern. Therefore elevated base level and braided stream formation result, rather than increased meandering, less overbank flooding, or reduced division, which require stable discharge.
