Which outcome occurs because of excessive fluvial sediment offloading contributing to coastal regions?

💡 Explanation

Extensive river sediment deposition increases discharge of distributary channels via progradation because channel creation and branching is proportional to the magnitude of offloaded sediment, rather than building stable systems; therefore, increased channel branching forms rather than marsh growth.
