Effects of topographic structure on salt marsh currents

The purpose of this study was to assess the spatial and temporal variability in overmarsh and in-channel currents, and to assess that variability in the context of salt marsh topographic structure. We created a high accuracy digital elevation model of a salt marsh island using a real time kinematic Global Positioning System. We measured currents with two velocimeters at the heads of adjacent Get price

Little River Salt Marsh Restoration Project

The Little River Salt Marsh is a back barrier marsh lying between Little Boar's Head in North Hampton and a rocky headland just south of North Shore Road in Hampton. The original marsh was approximately 193 acres in size, and had deteriorated over many years due to reduced tidal flow to the marsh. Get price

Herbivory Drives the Spread of Salt Marsh Die

Introduction. Salt marsh die-off is a growing phenomenon in the western Atlantic and a serious conservation problem as salt marshes provide valuable ecosystem services to coastal habitats .Landscape wide die-offs were first described over 35 years ago in Hudson Bay, Canada, where increasing geese populations, fueled by artificial nitrogen fertilizer use, led to runaway grazing and marsh Get price

How Healthy is Your Salt Marsh

The photo below shows aerial views of a salt marsh in New England with meandering tidal creeks that provide salt water to all parts of the marsh. It is the salt water that is the life blood of a salt marsh, as it limits the growth of species other than naturally adapted salt marsh vegetation. Get price

Salt Marsh

Aug 26, 2010Salt marshes are typically divided into a high, middle and low marsh zone based on elevation but responding to soil salinity established by tidal occurrence. Neap tides occur when the difference between high and low tide is the least, the lowest level of high tide occurring twice a month during the first and third quarters of the moon. Get price

Coastal Salt Marsh Management Along the Atlantic

Year Published: 2012 Responses of salt marsh ecosystems to mosquito control management practices along the Atlantic Coast (U.S.A.) Open marsh water management (OMWM) of salt marshes modifies grid-ditched marshes by creating permanent ponds and radial ditches in the high marsh that reduce mosquito production and enhance fish predation on mosquitoes.

Natural salt marshes with unaltered topography, as occur in Bahia de San Quintin, Baja California, Mexico, serve as reference systems for restoration of highly frag mented and degraded southern California marshes in the southwestern USA (West 2001).

Low Salt Marsh Guide

The number, aerial extent, and integrity of low salt marshes in New York are suspected to have declined substantially from their historical state. These declines are likely correlated with coastal development; dredging, ditching, and filling; and changes in hydrology, water quality, and natural processes. Get price

ESurf

These processes cause salt marshes to develop a distinctive, biologically mediated topographic structure consisting of several subhorizontal platforms, separated from tidal flats and from each other by a subvertical scarp and dissected by incising channels (Marani et al., 2007, 2013; Temmerman et al., 2007). The TIP method exploits this characteristic topography, which is clearly Get price

A Century of Oregon Salt Marsh Expansion and Contraction
