Which outcome results when flood control measures disrupt alluvial deposition?

💡 Explanation

Delta subsidence and coastal erosion occurs because sediment starvation from reduced alluvial deposition prevents natural land-building that *compensates for compaction*, *glacio-isostatic rebound* and sea level rise. Therefore, the delta subsides rather than accretes, exacerbating coastal erosion.
