Which outcome occurs following the moraine dam failure surrounding an alpine lake?

💡 Explanation

When a moraine dam fails, a glacial lake outburst flood (GLOF) occurs because rapid erosion happens unconstrained by base level controls, resulting in transport of large volumes of sediment downstream. Therefore, braided channels downstream result, rather than creating a lake, armoring slopes, or altering groundwater, which require different processes than that of glacial erosion and outburst flooding.
