HSGT?Competitive or Complimentary to Air Travel
The capacity of existing airports to meet increased travel demand is limited. Utilization of high speed ground transportation as a complimentary mode originating from major hub airports...

Cable-in-Conduit Superconductors for MAGLEV Magnet Systems
A major advantage of using a Nb₃Sn Cable-in-Conduit Conductor (CICC) for MAGLEV lies in its demonstrated capability to operate in supercritical helium....

High-Speed Rail's Prospects in Canada
This paper reviews the attractiveness of high-speed rail in Canada. It summarizes the findings of studies on the subject by VIA Rail, Canada's national passenger rail corporation. VIA...

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...

Modern Air Pollution Reduction Technology on Platforms in the Pacific OCS
The Pacific Outer Continental Shelf (OCS) along the California coast line has the most sophisticated air pollution reduction technologies implemented in the world. This paper describes...

Traffic and Lead Pollution on Lake Maracaibo's Western Coast
This project focused on Nerium Oleander (NO) (Berberia), an ornamental plant. Chemical analyses (acid digestion and atomic absorption spectrophotometry) of the plant's tissue and the soil...

Strategic Updating of Autonomous Route Guidance Systems for Air Quality Management
The work in this paper stems from applied research which is implemented as part of the QUARET project. QUARET is a major initiative by four European Community cities. Athens, Birmingham,...

Can Statistical Methods Help to Forecast Drought?
Relationships have been developed between rainfall in eastern Australia and both southern oscillation (SO) and sea surface temperatures (SSTs), and between rainfall in Ghana, West Africa...

Predicting Basin-Wide Tailwater Temperature Patterns by Combining Mechanistic and Statistical Water Quality Modeling
A simplified method for predicting water temperature patterns downstream of a peaking hydropower dam is described for the Fort Randall Dam tailwater of the mainstem Missouri River as part...

Modelling Studies of Gas Venting and Steam Injection for NAPL Site Remediation
A fully coupled, fully implicit method for simulating gas injection and steam injection for in situ remediation of sites contaminated with volatile NAPL is presented. Numerical results...

Modeling Water Table Response to Climate Change in a Norther Minnesota Peatland
Projections of global warming raise questions concerning the fate of wetlands in many parts of the world. In northern Minnesota, there is concern that the nearly 3 million hectares of...

Impacts of Potential Climate Change on Colorado-Big Thompson System Operations
The objective of this study is to examine the response of the Colorado-Big Thompson (CBT) system to specific local changes in climate, using the model CBTAOP to project the operating plan...

How is the Water Quality Affected by Droughts?
The moving average method was applied to daily time series of water quality and flow data obtained from a stream gaging station affected by the 1988 drought in the midwest of the United...

Estimating Runoff from Precipitation and Temperature
Increasing demands for water and the global climate change resulting from the CO₂ buildup in the atmosphere require an improved evaluation of surface-water...

Estimating ET Using Turbulent Coherent Structures
Two methods for estimating sensible heat flux to use in energy balance equations for computing crop evapotranspiration are discussed. The methods use high frequency temperature measurements...

Atmospheric Radiation Balance Over Alfalfa
An experiment was carried out in an alfalfa field in Logan, Utah, U.S.A., during 8-12 September 1992, to evaluate methods and expected accuracy of continuous radiation balance component...

Density Fluctuations and Use of the Krypton Hygrometer in Surface Flux Measurements
The magnitude of the of the Webb et al. (1980) density corrections on water vapor fluxes due to the flux of sensible heat is examined in terms of the Bowen ratio. The correction due to...

Evaluation of Electronic Temperature/Relative Humidity Sensors
Temperature and relative humidity measurements are routine parameters required for most agricultural meteorological applications. Reliable measurements of relative humidity, especially...

Updating Utah's Crop Water Use Estimates
Crop water use was estimated at National Weather Service stations throughout Utah for the 1961-1990 normal period. Daily weather data (air temperature, solar radiation, humidity, wind...
