Which outcome occurs when groundwater discharge exceeds infiltration capacities within an alluvial fan?

💡 Explanation

Landslides and debris flows are more likely because increased groundwater saturation elevates pore water pressure, therefore reducing shear strength through a mechanism called effective stress reduction, rather than enhancing stability or erosion which require drier conditions.
