The distribution of sediment textures within the study area. The bottom-type classification is from Barnhardt and others (1998) and is based on 16 sediment classes. The classification is based on four sediment units that include gravel (G), mud (M), rock (R), and sand (S). If the texture is greater than 90 percent, it is labeled with a single letter.

This model shows what Dauphin Island, Alabama, may look like under moderate storms but with increasing rates of sea level rise (Passeri and others, 2018).

The Herring River in Wellfleet, MA is a tidally-restricted estuary system. Management options including potential restoration of unrestricted tidal flows require an understanding of pre-restoration sediment conditions.

Meagan Gonneea checks on instruments at a tidal creek in Great Pond, Falmouth, MA. Daily tides drive exchange between coastal wetlands and adjacent estuaries. Here we have instrumented a tidal channel to measure those fluxes over a tidal cycle. When the marsh floods, material is imported from the estuary.

Gamma well detectors are used to determine the ages of sediments based on activities of natural and anthropogenic radionuclides
