Processes Affecting Coastal Wetland Loss in the Louisiana Deltaic Plain
Nowhere are the problems of coastal wetland loss more serious and dramatic than in the Mississippi River deltaic plain region of south-central Louisiana. In that area, rates of shoreline...

Short-Term Water and Suspended-Sediment Fluctuations in a Louisiana Marsh
To determine the timing of and driving forces for sediment suspension and deposition and the effect of impoundment, three self-recording instrument packages were deployed in a section...

Meteorological Forcing on Louisiana Wetlands
The open wetland areas of southern Louisiana are vulnerable to meteorological forcing. On the basis of over one year U.S.G.S. funded measurements of atmospheric pressure, air-sea temperature...

Marsh Submergence vs. Marsh Accretion: Interpreting Accretion Deficit Data in Coastal Louisiana
The apparent imbalance between relative sea-level rise and vertical marsh accretion is frequently cited as a major factor in the problem of wetland loss in Louisiana. Rates of relative...

Natural Resource Problem Solving: an Interdisciplinary Approach in Coastal Louisiana
Ecological issues such as coastal wetland loss cannot be adequately addressed by experts in any one particular discipline. After extensive consultation with wetland users and regulators,...

Coastal Wetlands of Ghana
The Ghanaian coast is overlain with over 50 lagoons and wetlands, which among others, are important wintering sites for European birds. Types, location and size of the wetlands are inventorised....

Are Landscape Patterns Related to Marsh Loss Processes?
Marsh loss that occurs in Louisiana is seldom associated with shoreline erosion of lakes and bayous; instead, marshes break up internally. Marsh loss is attributed to processes that stress...

Production and Decomposition of Spartina patens in a Degrading Coastal Marsh
Production and decomposition rates were calculated for Spartina patens in a mesohaline coastal marsh in Louisiana. Production was estimated to be 800 g m-2 ur-1 during 1991 and 1,696 g...

Crevasses on the Lower Course of the Mississippi River
Before construction of artificial levees, crevasses were a common event along the Mississippi River. They directed sediment out of the main channel and reduced flood stage down river....

A Global Vulnerability Assessment: Vulnerability of Coastal Areas to Sea-Level Rise
Assessment of the global vulnerability (GVA) of the various resources of the world's coastal zone to an acceleration of sea-level rise (ASLR) and related climate change effects requires...

Holocene Sedimentation and Coastal Wetlands Response to Rising Sea Level at the Aucilla River Mouth, a Low Energy Coast in the Big Bend Area of Florida
The shallow dip of the Florida carbonate platform results in low wave energy on Florida Big Bend coasts. Therefore sedimentation is dominated by river-and tidal-hydrodynamics near the...

Plant Establishment Enhancement Technique for Shoreline Stabilization and Protection
Once established, vegetation is capable of significantly reducing erosion along streams, rivers, bays, sounds and other tidal shorelines. In the last 15 years, many attempts to establish...

Washington State Coastal Erosion Management Strategy
The shores of Washington's inland coast - Puget Sound - undergo chronic and episodic erosion and landsliding. The problem is not nearly so great here as elsewhere in the U.S.A., but what...

A Workstation for the Extraction of Coastline from Digital Imagery
The delineation of coastline has primarily been a manual tracing exercise from various forms of imagery. In this paper, a process to extract shoreline automatically from digital imagery...

Remote Sensed Information System in Marine Management
Today computer and GIS are being used to join marine resources and environmental management, and remote sensed data is becoming more and more important data sources of GIS. Along with...

GIS and Laboratory Study Contaminants in Wetlands
Geographical Information Systems (GIS) provide excellent visualization and analyses of where pollution sources are located relative to existing wetland resources and areas of significant...

State Implementation and Enforcement of the Alaska Coastal Management Program
Section 306 the Coastal Zone Management Act of 1992 required participating states to develop a means to implement and enforce their coastal programs. The Alaska Coastal Management Act,...

Industry and Agencies Join Forces to Improve Water Quality
Southeastern Egg and Poultry Association (SOUTHEASTERN), Soil Conservation Service (SCS), Environmental Protection Agency (EPA) and Tennessee Valley AUthority (TVA), Extension Service...

The Permitting Process for Oil Exploration and Development Projects on the North Slope of Alaska?An Oil Company Perspective
The five oil fields of Alaska's North Slope, including the giant Prudhoe Bay field the largest oil field in North America, contribute approximately 25% of United State domestic oil production...

Predicting Impacts of Management Measures on Fragile Coastal Wetlands Using a Predictive Landscape Model
We present a marsh development model that incorporates the hydrodynamics of erosion and sedimentation and meets all conventions proposed for spatial landscape modeling. Wave parameters...
