← GeographyWhich outcome results as rivers discharge into coastal delta systems with significant sediment load and reduced flow rate during the dry season?
A)Accelerated longshore drift dominates✓
B)Oxbow lake formation increases
C)Glacial isostatic rebound slows
D)Subduction zone volcanism reduces
💡 Explanation
Accelerated longshore drift occurs, because increased sediment deposition at river mouths, combined with reduced river flow to dislodge it, strengthens wave-driven transport. Therefore, longshore drift dominates, rather than other geomorphic fluvial or tectonic processes under these conditions.
