Which outcome commonly arises when human infrastructure disrupts longshore sediment transport?

💡 Explanation

Intensified barrier island breaching occurs because, when groins or jetties interrupt longshore drift, sediment starvation downstream weakens the barrier island structure, therefore making it more susceptible to breaching, rather than altering tectonic or mantle processes.
