Which ecosystem change occurs when extensive alluvial mining interrupts sediment transport?

💡 Explanation

Downstream delta lobe abandonment occurs because sediment starvation caused by interrupted transport results in reduced deposition, diminishing land build-up; therefore, the delta switches, rather than accretion occurring in the estuary, which is an alternative outcome.
