Which outcome occurs when a glacial lake outburst flood (GLOF) erodes a moraine dam?

💡 Explanation

When a GLOF erodes a moraine dam, extreme discharge occurs because incision and sediment transport increases, leading to a wider, shallower channel morphology. Therefore braided stream networks form downstream, rather than isostatic rebound acceleration, increased methane release, or enhanced delta deposition rates, which require different triggers.

• Which risk increases when deep ocean upwelling stagnates?
• Which mechanism causes higher sediment deposition rates along the upper regions alluvial fans?
• Which process initiates oxbow lake formation when a river's channel migrates laterally?
• Which process causes increased stream meandering downstream in a humid, temperate region due to deforestation?
• Which effect accelerates when a permafrost active layer experiences increased thawing and saturation?
• Which process results from increasing sediment load on a river flowing across a coastal alluvial plain?
