Salt wedge dynamics lead to enhanced sediment trapping within side-embayments in high-energy estuaries

Editors’ Highlight—This study seeks to better understand the accumulation and deposition of sediments in estuarine environments. Looking specifically at an off-river cove in the Connecticut River, the authors combine a number of techniques not normally deployed together – including multiple databases, dating, provenance, and modeling studies – to characterize sediment trapping in side-embayments. They find that that sedimentation within protected coves is related to low flows and greater intrusion of the saltwater wedge, rather than high-stage events. This finding is important in view of potential future sea-level rise because sediment accumulation in off-river coves will likely extend upriver.
