Which outcome accelerates subsidence in heavily irrigated alluvial basins?

💡 Explanation

Enhanced oxidation of buried organic matter in alluvial sediments cause volume reduction leading to surface down-warping because it reduces the structural support of the soil, therefore land subsidence accelerates rather than stabilizing with compaction alone.
