Which consequence results when increased sediment accretion closes a barrier island inlet?

💡 Explanation

Inlet closure reduces tidal exchange because decreased water volume in the tidal prism limits the flow. This inlet sedimentation changes morphological forcing, which results in channel infilling; therefore a smaller tidal prism results, rather than increased salinity which would occur with increased evaporation.
