Which risk increases when extensive coastal development prevents sediment supply in a delta?

💡 Explanation

Accelerated delta collapse occurs because diminished sediment deposition reduces the load, triggering sediment compaction. This elevates the risk of subsidence because isostatic rebound cannot compensate. Therefore, collapse increases, rather than any seismic change.
