Changes in groundwater tables brought about by sea level increases in the Delaware River Basin (near Philadelphia) about 2,500 years B.P., initiated wetland development at the Princeton-Jefferson Branch of the Woodbury Creek marshes. Continual increases in sea level pushed groundwater tables further upward, and by approximately 800 years B.P., groundwater tables had risen to the upper limits for woody vegetation at the site. By the time European settlers arrived in the late 1600s nontidal sedge… 
Prehistoric habitat stability and post-settlement habitat change in a Chesapeake Bay freshwater tidal wetland, USA
Analyses of fossil seeds and pollen grains preserved in seven sediment cores and borings were combined with historical land-use records to reconstruct an 1800-yr history of Otter Point Creek (OPC), a
PALEOECOLOGY OF SUBMERGED MACROPHYTES IN THE UPPER CHESAPEAKE BAY
Fossil seed distributions of submerged aquatic vegetation (SAV) from dated sediment cores in tributaries of the upper Chesapeake Bay show prehistoric changes in species composition and abundance and
Some applications of paleoecology to the management of tidal marshes
TLDR
Paleoecology has the potential to provide much insight into the development of the system, particularly when the impacts of accelerated sea-level rise on vegetation and sedimentation dynamics in tidal marshes is being considered.
Sustainability of a Tidal Freshwater Marsh Exposed to a Long-term Hydrologic Barrier and Sea Level Rise
A 115-year-old railroad levee bisecting a tidal freshwater marsh perpendicular to the Patuxent River (Maryland) channel has created a northern, upstream marsh and a southern, downstream marsh. The
Holocene environmental change in the inner Severn estuary, UK: an example of the response of estuarine sedimentation to relative sea-level change
Holocene sediments of the wetlands around the inner Severn estuary, UK, demonstrate a consistent stratigraphy of a single woody peat layer, up to at least 4.5 m thick, capped with a grey, silty clay.
Sedimentation cycles in a river-mouth tidal freshwater marsh
Tidal freshwater marshes are critical buffers that exist at the interface between watersheds and estuaries. Little is known about the physical dynamics of tidal freshwater marsh evolution. Over a

Research on sedimentation processes in tidal freshwater marshes is lagging far behind that for salt marshes despite the importance of tidal freshwater systems for understanding impacts of watershed
Catastrophes, Near-Catastrophes and the Bounds of Expectation: Success Criteria for Macroscale Marsh Restoration
Most tidal marsh on Delaware Bay has a history of diking for purposes of salt hay (Spartina patens) production and wildlife management. Extensive ditching for drainage and mosquito control has also

The Development of a Tidal Marsh: Upland and Oceanic Influences
TLDR
Results showed that tidal marsh sections can provide sensitive records of both upland and marsh vegetation histories, pollen and macrofossil records can be closely linked to tide—gauge records and are responsive to short—term changes in sea level with a high degree of temporal resolution, and upland influences can play an important role in determining the course of plant succession in the intertidal environment.

TLDR
The measurements to be reported of the radiocarbon age of peat recovered from various depths in salt marshes on Cape Cod, at Barnstable, Massachusetts, were made to determine the rate of vertical accretion of the high marsh peat and thus provide a chronology of the development of these marshes.
Development of a New England Salt Marsh
The salt marsh at Barnstable, Massachusetts, occupies an embayment into which it has spread during the past 4,000 years. It exhibits all stages of development from the seeding of bare sand flats

A salt marsh responds in many diverse ways to a rising sea level. A major factor is its ability to maintain surface elevations with respect to the mean high water level. Other influences include

TLDR
This discussion of the structure, function, and value of freshwater tidal wetlands is based on studies of three Delaware River wetlands: the Hamilton Marsh near Trenton, NJ, Woodbury Creek Marsh south of Camden,NJ, and Tinicum Marsh near Philadelphia, PA.
