Sedimentation cycles in a river-mouth tidal freshwater marsh

  author={Gregory B. Pasternack and Grace S. Brush},
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 21-mo period, July 1995 to March 1997, measurements were made of biweekly sediment deposition at 23 locations in a 3.8-ha tidal freshwater marsh in the Bush River subestuary of the upper Chesapeake Bay. Biweekly accumulation showed high spatial and temporal variability, ranging from −0.28 g cm−2 to 1…

Biogeomorphology of an upper Chesapeake Bay river-mouth tidal freshwater marsh

Field mapping and monitoring of vegetation, sedimentation patterns, substrate characteristics, and geomorphology in the Bush River tributary to upper Chesapeake Bay has been conducted since 1991 to

Seasonal Variations in Sedimentation and Organic Content in Five Plant Associations on a Chesapeake Bay Tidal Freshwater Delta

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

Influence of Inundation and Suspended-Sediment Concentrations on Spatiotemporal Sedimentation Patterns in a Tidal Freshwater Marsh

Long-term marsh sustainability is threatened by environmental changes, especially accelerated rates of sea-level rise (SLR) and changing fluvial sediment supplies. Although direct observations of

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

Sediment Deposition and Accretion Rates in Tidal Marshes Are Highly Variable Along Estuarine Salinity and Flooding Gradients

Vertical accretion in estuarine marshes depends on rates of sediment deposition and is a complex function of different interacting variables. In times of climate change and associated sea-level rise,

Sediment nutrient accumulation and nutrient availability in two tidal freshwater marshes along the Mattaponi River, Virginia, USA

Sediment deposition is the main mechanism of nutrient delivery to tidal freshwater marshes (TFMs). We quantified sediment nutrient accumulation in TFMs upstream and downstream of a proposed water

The Role of Sedimentation in Estuarine Marsh Development within the San Francisco Estuary, California, USA

Abstract Friedrichs and Perry (2001) have hypothesized that exogenous sedimentation is a vital part of a feedback system (with tidal height, marsh elevation and local vegetation) that keeps the marsh


Hydrology can be difficult to interpret in tidal freshwater forested wetlands because of several influencing factors including river discharge, tidal stage, local precipitation, evapotranspiration,



Nutrient and metal accumulation in a freshwater tidal marsh

Stratigraphic records from sediment cores collected in a freshwater tidal marsh and in the estuary upstream and downstream from the marsh were used to determine the accumulation of nutrients and

Patterns of sediment deposition in subsiding coastal salt marshes, Terrebonne Bay, Louisiana: The role of winter storms

High rates of wetland loss in the Mississippi deltaic plain have been attributed to a combination of insufficient marsh sedimentation and relative sea-level rise rates of over 1.2 cm yr−1. This study

Rates of sediment accumulation in a tidal freshwater marsh

ABSTRACT Rates of sediment accumulation were determined for a Delaware River tidal freshwater marsh utilizing radiometric, palynological and sediment flux estimating techniques plus historical

The Ecology of Freshwater Tidal Wetlands

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.

Flux of particulate matter in the tidal marshes and subtidal shallows of the Rhode River estuary

There was a net influx of suspended particulate matter to the uppermost part of the Rhode River estuary during the several years of this study. Most of the influx was due to episodic discharges of

Comparison of detritus dynamics in two tidal freshwater wetlands

We have examined the generation and persistence of detritus in two con- trasting tidal freshwater wetlands on the Hudson River. These wetlands offer a difference in vegetation, with Tivoli South Bay

Upland and Coastal Sediment Sources in a Chesapeake Bay Estuary

Abstract Rapid sedimentation in the upper and central portions of tributary estuaries of the Chesapeake Bay typically has been attributed to clearing of land and subsequent upland erosion since

Cap-Tourmente tidal flat is located on the north shore of the St. Lawrence middle estuary, 50 km downstream from Quebec city, Canada. Seasonal variations in sedient accretion were studied during the


Historically, tidal freshwater environments have been ignored by limnologists because of the presence of oceanic tidal influence, and neglected by marine ecologists because they are bathed by freshwater and inhabited primarily by freshwater organisms.
