Managing Beach Erosion in Fortaleza, Brazil
The littoral of the metropolitan region of Fortaleza City, State of Ceara in the Northeastern part of Brazil, has suffered significant morphological changes during this century. There...
The Source of Sediments in the Neuse River Estuary: Water Quality Management Implications
Pedological evidence in alluvial floodplains of the fluvial-estuarine transition zone of the Neuse River, North Carolina, shows that very little sediment from the Piedmont headwaters of...
Heavy Metal Accumulation in Subsurface, Estuarine Sediments and Inferences for Anthropogenic Enrichment: N.W. Florida Coast
In an attempt to quantify the degree of contamination and the thickness of the contaminated subsurface sedimentary wedge, approximately 100 samples were extracted from the cores and subjected...
Sedimentation Patterns of a Restored Tidal Wetland
Coyote Slough Lagoon was flooded as part of a local mitigation project in 1986. The design of the restored marsh included peninsulas to break up the local fetch and resulted in the development...
Geological Characterization of Selected Offshore Sand Resources on the OCS, Offshore Alabama, for Beach Nourishment
Most Alabama Gulf and estuarine shoreline is undergoing long-term erosion; threatened shorelines will need programs of replenishment and maintenance if they are to be even temporarily...
Subsidence Properties of Holocene Sediments: S. La.
As part of a comprehensive USGS-sponsored study of processes that drive subsidence and wetland loss in south Louisiana, two continuously cored deep borings (60 m and 72 m) were acquired...
A Guide for Controlling Agricultural Nonpoint Source Sediment Loads: Where to Treat?
The authors present a simplified guide to decide where to expend money and efforts to reduce sediment loads that cause water quality problems. This guide is intended for resource managers...
Measuring the Effect of Sediment Fences for Wetland Creation and Restoration in Louisiana
A sediment erosion table (SET) method has been developed to monitor changes over time in intertidal mudflat or pond elevations with an accuracy in the 1.5 mm range. The SET permitted rapid...
Environmental Impacts of Small Boat Navigation: Vessel/Sediment Interactions and Management Implications
It is the intent of this review and discussions to provide state-of-the-art information on one aspect of the issue of environmental impacts associated with small boat navigation, that...
Oil in the Intertidal and Subtidal Sediment of the Saudi Arabian Coast One Year After the Gulf War Oil Spill
One year after the Gulf War oil spill, studies were conducted on the distribution and fate of oil in intertidal and shallow, subtidal habitats along the Saudi Arabian cost. These studies...
The Development of Fishery Habitat Value in Created Salt Marshes
This Coastal Ocean Program project was designed to examine the functional developmental rate of ten created marshes ranging in age from 3 or 15 years in the Galveston Bay system of Texas....
The Napeague Dunes, Long Island, NY
The Napeague Dunes of eastern Long Island, N.Y., consist of a series of three migrating parabolic dunes. The area presently occupied by this system was formerly a 2.7 Km wide inlet following...
Shoreline Processes and Beach Changes on the Lagoon Shoreline at Fire Island National Seashore, NY, USA
Shoreline processes and beach changes on the lagoon shoreline at Fire Island national seashore, NY, USA are discussed in this paper....
Analysis of Marsh Sedimentation Changes, Cumberland Island, Georgia
The national park service has initiated a long-term monitoring project to determine whether dredging for the King's Bay Naval Base is affecting sedimentation and erosion rates in the backbarrier...
Assessment of Technological Approaches for Measuring Wetlands Changes
Efforts to establish causal relationships have led a number of researchers to develop techniques for assessing changes in marsh environments. Until recently these techniques for assessing...
Laboratory Testing of an Artificial Reef Erosion Control Device
A physical model study has been conducted to examine the effectiveness of a concrete artificial reef in limiting offshore, storm-induced sand loss from a nourished beach. The experiment...
Management and Engineering at Araruama Lagoon, Brazil
Contrary to generalized expectations, the shores of Araruama Lagoon turned out to be abundant of examples of morphological changes, primarily due to disregard of basic coastal engineering...
Upper Watershed Management and Sedimentation in Mugu Lagoon, Ventura County, California
Mugu Lagoon is one of the last remaining, natural salt marsh systems in southern California. In the last 90 years, sedimentation in the lagoon has increased from a geologic rate of 0.17...
Chlorinated Pesticide in a Fish Farming Station in the Lake Maracaibo Basin
The present evaluation of chlorinated pesticides is the result of the detection of tumors, hepatic and renal necrosis and skeletal anomalies in species of fish cultivated in artificial...
Potential for the Bioremediation of Contaminated Dredge Material
Sediment contamination frequently impacts the ability of ports to maintain and deepen shipping channels. One of the common contaminants in channel sediments is polycyclic aromatic hydrocarbons...
