Sediment and Other Particulate Retention in NH Wetlands (Derived from NWI Plus)

This dataset models the potential of wetlands in New Hampshire to perform the critical function of sediment and other particulate matter retention. Created using the National Wetlands Inventory Plus (NWI Plus) classification system, the layer identifies wetlands that are likely to capture and filter sediments transported by surface runoff. Wetlands that perform this function help reduce downstream sedimentation, protect aquatic habitats, and improve water quality. This dataset is a valuable tool for watershed planning, stormwater management, nonpoint source pollution control, and conservation prioritization. It should be used as a landscape-scale screening tool, with additional site-level assessments recommended for regulatory or engineering applications.
