Which risk increases most within lagoon environments landward of a barrier island undergoing overwash?

💡 Explanation

Decreasing coastal marsh accretion occurs because overwash deposits sand into the lagoon environment, burying the marsh and hindering its vertical growth. This sediment influx overwhelms the plant's ability to accrete, therefore accretion decreases, rather than facilitating marshland growth.
