Which consequence develops within a fjord when a glacial ice dam suddenly collapses?

💡 Explanation

When a glacial ice dam collapses, a massive pulse of water with high sediment load is released into the fjord, increasing hydrodynamics and sediment deposition because the rapid flow scours surrounding landscapes. Therefore, increased coastal erosion results rather than salinity changes, methane release, or oxygen depletion which require sustained changes, not pulse events.
