Which risk increases when excessive sediment load overwhelms a river's alluvial fan system in a tectonically active region?

💡 Explanation

Increased sediment overwhelms the channels, causing channel blockage which results in avulsion; therefore, the river will find new, less obstructed routes which leads to more avulsion events, rather than creating stable deposits because deposition shifts rapidly.
