Which hazard is magnified when managed river sediment transport discontinues?

💡 Explanation

Coastal pinch points increase primarily due to disrupted sediment deposition; longshore drift reduction initiates this, because sediment starvation amplifies erosion. Therefore, the 'coastal squeeze' due to flooding risk increases exponentially, rather than ozone or volcanic eruption rates increasing.
