    • Hydrogeomorphic data along transitioning Coastal Plain rivers (Mattaponi and Pamunkey Rivers): implications for a rising sea level

    Metadata Updated: January 21, 2026

    Data on changing hydrogeomorphic characteristics and suspended sediment availability along river gradients from nontidal through tidal freshwater to oligohaline reaches along the Mattaponi and Pamunkey Rivers, Virginia. Characteristics include suspended sediment concentrations and specific conductivity in river water, and elevation of geomorphic units along digital cross-sections (both from edges of valley wall and from edges of fluvial system) from lidar digital elevation models, satellite visible imagery, and geographic information system analysis. These characteristics were used to interpret fundamental changes in regime along rivers as they transition from watersheds into the coastal zone.
