← GeographyWhich outcome occurs when rapid alluvial deposition obstructs established waterways?
A)Braided stream channel formation✓
B)Regional climate stabilization
C)Increased groundwater infiltration rates
D)Enhanced coastal erosion control
💡 Explanation
Braided streams form due to sediment load overwhelming a river; the decreased channel capacity, because of alluvial aggradation, results in the water splitting into multiple channels. This occurs rather than climate stabilization, increased infiltration, or erosion enhancement; therefore, a braided stream occurs.
