A newly formed glacial lake breaches its moraine dam; which process controls flash flood development downstream?

💡 Explanation

Flood waves surge forward in a hydraulic jump because the rapid deceleration causes energy dissipation and rising water rather than wave propagation; therefore a hydraulic jump indicates dangerous water volume increase, rather than mere ablation processes.

• Which topographic outcome characterizes landscapes undergoing extensive solifluction?
• Which outcome occurs when repeated freeze-thaw cycles saturate high-latitude silty soils on a moderate slope?
• Which deposition outcome characterizes rapid flow deceleration below a mountain range?
• Following persistent dilute acid rain incidence, which outcome accelerates soil degradation?
• Which outcome occurs when ice exceeds cirque capacity?
• Which feedback results from ice sheet melting exposing land?
