Which outcome occurs when decreased river competence deposits oversized alluvial components?

💡 Explanation

Braided streams form downstream because reduced flow competence can no longer carry larger sediments; therefore sediment sorting leads to multiple, unstable channels, rather than a single, meandering channel that grades finer materials.
