Which 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.
