← GeographyWhich consequence results when increased sediment load exceeds capacity?
A)Braided stream channel formation occurs✓
B)Base level stabilizes instantaneously downstream
C)Laminar flow regime becomes universally dominant
D)Dissolved load increases proportionally, linearly
💡 Explanation
Braided stream channels result from increased sediment because decreased channel efficiency causes a widening and splitting of the flow via aggradation, rather than a stable channel arising from laminar flow or a constant base level; sediment transport processes dictate fluvial morphology.
