Which risk increases when sediment supply exceeds stream transport capacity near mountain fronts?

💡 Explanation

Increased flow-path roughness creates an alluvial fan; because a larger volume in the system experiences increased hydraulic resistance, flash floods become frequent as local infiltration is less efficient than overall surface flow and saturation. Therefore, magnitude increases, rather than other choices reflecting different scales or environments.
