Water Quality Control: Integrating Beneficial Use and Environmental Protection (Summer Conference, June 1-3)
Conference organizers and/or faculty included University of Colorado School of Law professors David H. Getches, Lawrence J. MacDonnell and Charles F. Wilkinson.
Protecting water quality is essential to preserve the many beneficial uses of western water resources. This conference addresses the dominant federal requirements in the Clean Water Act, including the important major revisions enacted by Congress in 1987, with special attention to western problems regarding nonpoint source pollution. Developments in groundwater quality regulation are considered, as are selected issues concerning the implications of state and federal water quality regulation for the traditional exercise of water rights.

Long-Term Reconstruction And Analysis Of White River Streamflow, M. K. Cleaveland, D. W. Stahle, J. G. Hehr
Arkansas Water Resources Center Technical Reports
A 281-year reconstruction of White River annual runoff at Clarendon, Arkansas, was developed from a regional average of nine Oklahoma, Missouri, and Arkansas tree-ring chronologies (six post oak, Quercus stellata, and three baldcypress, Taxodium distichum). Inhomogeneity of the gaged series was detected with both double mass analysis (using state average total annual Arkansas precipitation) and regression (using the regional tree-ring average). Simple regression calibrated the homogeneous runoff data with the average ring width data from 1930 to 1980. Comparing the reconstruction with independent data verified the regression model. Variance of the reconstruction increases significantly during the 20th century, a change …

National List Of Plant Species That Occur In Wetlands: Intermountain (Region 8), Porter B. Reed, Jr., National Ecology Research Center
All U.S. Government Documents (Utah Regional Depository)
The National List of Plant Species That Occur in Wetlands represents the combined efforts of many biologists over the last decade to define the wetland flora of the United States. The U.S. Fish and Wildlife Service initially developed the list in order to provide an appendix to the Classification of Wetlands and Deepwater Habitats of the United States (FWS/OBS 79/31) to assist in the field identification of wetlands. Plant species that occur in wetlands, as used in the National List are defined as species that have demonstrated an ability to achieve maturity and reproduce in an environment where all or …

Dredging Management: A Comparative Analysis Of Mid-Sized U.S. North Atlantic Ports, Matthew H. Masters
Marine Affairs Theses and Major Papers
Dredging management within the states of Rhode Island, Maine and Connecticut is examined through an analysis of the ports of Providence, Portland, and New Haven. These ports were selected from a field of 30 Atlantic Coast ports through a multivariate statistical analysis, based on similarities in size, function and geography. Each port's dredging history was compiled to illustrate the frequency and magnitude of dredging activity among the three states. Pertinent state laws, regulations and policies regarding dredging and dredged material disposal were reviewed in an attempt to identify similarities and differences. It was believed that differences among each state's regulatory …

Wetland Characteristics Of Avian Cholera Outbreaks And Surface Water Transfer In The Nebraska Rainwater Basin Area, Brian J. Smith
Wetland Characteristics Of Avian Cholera Outbreaks And Surface Water Transfer In The Nebraska Rainwater Basin Area, Brian J. Smith
Electronic Theses and Dissertations
Avian Cholera (Pateurella multocida) has infected and killed thousands of migrating waterfowl each year since 1975 in Nebraska’s rainwater basin area. Disease outbreaks in migrating waterfowl populations just prior to the nesting season are of concern to biologists. Feedlots and itner-wetland basin surface water transfer mechanisms of the avian cholera causative agent, P. multocida, were investigated using remote sensing techniques. Wetland basin characteristics (classification type, adjacent landuse, basin landuse, and basin densities) were also investigated for relationships to 1981 avian cholera outbreaks. No surface drainage relationships were found that would permit the transfer of P. multocida from one wetland basin …
Carbon Dioxide Emissions And Fossil Fuel Consumption A Canadian Perspective, John Peter Doucet
Carbon Dioxide Emissions And Fossil Fuel Consumption A Canadian Perspective, John Peter Doucet
Theses and Dissertations (Comprehensive)
The potential climate change due to increased loading of carbon dioxide in the atmosphere has emerged as one of the most significant environmental threats of the late twentieth century. An analysis of a variety of feasible energy demand scenarios for Canada indicates that if we continue to consume the same types and proportions of fuels as we do today, the expected demand for energy in the year 2005 would yield carbon dioxide emissions up to 52.5 per cent greater than that of 1985. On the other hand, if Canada were to alter the types and quantities of fuels required to …

Maritime Boundaries Between Trinidad And Tobago/Venezuela/Barbados And Grenada - Its Impact On Offshore Oil, Patty Marajh
Maritime Boundaries Between Trinidad And Tobago/Venezuela/Barbados And Grenada - Its Impact On Offshore Oil, Patty Marajh
Marine Affairs Theses and Major Papers
The future of the economy of Trinidad and Tobago is heavily dependent upon the exploitation of the hydrocarbon resources in its continental shelf. Trinidad's geographical proximity to the Venezuelan mainland is relevant because both states share the same continental shelf in areas not delimited by the 1942 gulf of Paria Treaty. The continental shelves of Barbados and Grenada also intersect and these areas have not been delimited and defined by any agreement. The current expansion of the exploration and exploitation of crude oil and natural gas have raised several problems within recent years. This thesis will focus attention to the …

Seepage Interceptor Drains And Topsoil Salinity, T R. Negus
Journal of the Department of Agriculture, Western Australia, Series 4
The Department of Agriculture established 121 trials in its Narrogin advisory district starting in 1972 to measure the effect of bulldozer and grader built seepage interceptor banks and drains on the topsoil salinity of the land downslope of them.
After 14 years of moniterin, there was no evidence that seepage interceptor drains and banks reduced the top soil salinity on 10 of the 11 sites in the Pingelly, Brookton and Wickepin Shires.

Genesis Of Marine Terrace Soils, Barbados, West Indies: Evidence From Mineralogy And Geochemistry, Daniel R. Muhs, Russell C. Crittenden, John N. Rosholt, Charles A. Bush, Kathleen C. Stewart
United States Geological Survey: Staff Publications
Well-developed, clay-rich soils dominated by interstratified kaolinite-smectite are found on the uplifted coral reef terraces on the island of Barbados. The reef limestone is unlikely to have been the soil parent material however, because it is 98 per cent CaCO, and geomorphic evidence argues against the 20 m of reef solution required to produce the soils by this process. The mineralogy of the sand, silt, and clay fractions of the soils, and trace element geochemistry, suggest that aeolian materials carried on the trade winds from Africa, volcanic ash from the island of St. Vincent, and quartz from Tertiary bedrock on …
