Which risk during periods of high sediment load increases where a river flows into a natural lake?

💡 Explanation

Accelerated delta formation occurs because increased sediment supply enhances deposition at the river-lake interface through the progradation mechanism. This causes rapid sedimentation rather than maintaining lake volume. Oxygen levels decline, not increase, due to decomposition of organic matter.
