Global Climate Change: USFWS Coastal Research
Scenarios of global climate change are still ambiguous; however, increasing sea level and atmospheric carbon dioxide (CO2) concentrations seem certain,...
Shell Island Evolution
In 1979, Shell Island was overtopped by Hurricane Bob breaching the barrier island with an opening that now has increased to a width of approximately 2.7 kilometers. Saltwater intrusion...
NDBC's Observations in the Coastal Zone
The National Data Buoy Center (NDBC) has been collecting data from coastal buoys since 1979. Measurements, taken each hour, include wind direction, wind speed, significant wave height,...
Shear Velocity and Eolian Sand Transport on a Barrier Island
Nearly 18 months of simultaneous measurements of atmospheric shear velocity, sand transport quantity, and beach erosion survey were made to investigate the rate of eolian sand transport...
Geologic Controls on the Formation and Evolution of Quaternary Coastal Deposits of the Northern Gulf of Mexico
A study of the barrier islands and wetlands in the deltaic plain of Louisiana is presented. Its purpose was to document rapid changes and to learn more about the processes responsible...
Late Quaternary Geologic Framework, North-Central Gulf of Mexico
The geologic framework of the north-central Gulf of Mexico shelf is composed of multiple, stacked, delta systems. Shelf and nearshore sedimentary facies were deposited by deltaic progradation,...
Processes Controlling the Retreat of the Isles Dernieres, A Louisiana Barrier-Island Chain
The Isles Dernieres is a low-lying, transgressive barrier-island chain situated about 150 km west of the modern Mississippi delta. Much of the Isles Dernieres consists of highly dissected...
Cyclonic Events and Sedimentation in the Gulf of Mexico
An ample literature exists documenting the destructive effects hurricanes have upon offshore barrier islands and coastlines. The Gulf of Mexico region has been especially heavily impacted...
Implications of Accelerated Sea-Level Rise on Louisiana Coastal Environments
Natural and human-induced processes have combined to produce high rates of relative sea-level rise and coastal land loss in Louisiana. This paper presents historical trends in sea-level...
Historical Morphologic Evolution and Sedimentation at Barataria Pass, Louisiana
Barataria Pass, Louisiana, one of the most commercially important tidal inlets in the Gulf of Mexico, has undergone several stages of development since 1840. The shore-parallel growth...
Evaluation of the City of Venice Urban Reuse Program
The City of Venice is located on the Gulf of Mexico in west central Florida. With a mild sub-tropical climate and coastal location, the small community is a prime target for rapid development....
Modeling Analysis of CSO Impacts in a Tidal Basin
Short duration intensive inflows of combined sewer overflows (CSO) to marine tidal basins create stratified water quality for limited periods of time. Accurate assessment of water quality...
A Case for Modernizing the Funding and Repayment of Regional Water/Power Projects
Several regional water/power projects authorized by Congress remain unfunded and therefore uncompleted year after year. In this paper examples of such uncompleted projects are examined....
The Mt. Hope Waterpower Project
The Mt. Hope Waterpower Project is a 2000 megawatt, underground pumped-storage hydroelectric power project located on the site of an inactive iron mine in the township of Rockaway, New...
Outlet Works Modifications at Abiquiu Dam
For the installation of a hydroelectric project at the Corps of Engineer's Abiquiu Dam in New Mexico, outlet works modifications that would not affect the structural integrity,...
Alfalfa ET Measurements with Drainage Lysimeters
Drainage lysimeters were used to measure alfalfa evapotranspiration (ET) under a line-gradient sprinkler system in the high-elevation desert conditions of northwest New Mexico. The lysimeters...
Efficient Water Use in Irrigated Wheat
Border irrigated wheat is the main crop in arid, semiarid and winter-dry areas in Mexico. In general water use efficiency is low, since border irrigation systems are not well designed...
Effects of Uranium Mining, Puerco River, New Mexico
Effluent from uranium-mine dewatering and acidic water released by a tailings-pond dike failure increased radionuclide activities in streamflow in the Puerco River in New Mexico and Arizona....
Uncertainty in Climate Change and Drought
A series of projections of climate change were applied to a watershed model of the Delaware River basin to identify sources of uncertainty in predicting effects of climate change on drought...
Design of Groins on the Middle Rio Grande
The Albuquerque Projects Office of the Bureau of Reclamation wanted to use groins in place of revetments at two sites on the Rio Grande. The Bureau of Reclamation has limited experience...
