Which outcome results when coarse sediment deposition overwhelms a drainage network at a mountain range base?

💡 Explanation

When coarse sediment deposition overwhelms a drainage network, aggradation occurs because the river's transport capacity is exceeded, leading to channel instability and the splitting of flow around sediment bars. Therefore a braided stream results, rather than meanders, terraces, or karst, requiring different geological conditions.
