Which outcome reduces coastal wetland health when sand accumulates?

💡 Explanation

Inlet migration occurs via longshore transport and dune migration blocking connections because sediment deposition overwhelms tidal flushing capacity initiating new pathways; therefore, less tidal exchange causes stagnation rather than biodiversity or fresh-water infiltration through sediment.
