← GeographyWhich change increases the sinuosity of meandering streams?
A)Increased variability of stream discharge✓
B)Stabilized base level of stream inflow
C)Decreased vegetation of watershed valley
D)Reduced gradient of longitudinal profile
💡 Explanation
Increased discharge variability enhances differential erosion/deposition. The increased *lateral migration* makes the stream more sinuous, because flow path changes are extreme, rather than just cutting downwards, while consistent flow smooths the path.
