Which outcome occurs when a glacial lake outburst?

💡 Explanation

Increased sediment deposition results due to catastrophic flooding. Downstream valleys experience a surge of water and sediment via the **hydrodynamic jump** mechanism; therefore, deposition increases rather than decreases because increased flow energy facilitates greater sediment transport.

• Which mechanism increases flood extent past a levee during a prolonged river flood?
• Which landform develops when freeze-thaw cycles and permafrost cause creeping downslope movement of saturated soil?
• Which atmospheric effect causes deflection of prevailing winds forming distinct east-west bands?
• Which event strongly promotes accelerated karst topography development?
• Which feedback arises when increased rainfall rapidly saturates soluble bedrock, forming new sinkholes?
• Which feedback mechanism enhances cirque formation at high altitudes?
