Sacramento and Trinity River Systems: A Demonstration of River Temperature Management for the 90's
Drought in Northern California resulted in the potential that summer and early fall, 1992, Sacramento and Trinity River temperatures would exceed critical levels for sustaining salmon...

Non Contact, Remote Sensing of Buried Water Pipeline Leaks Using Infrared Thermography
Subsurface water pipelines, sewer and buried utilities throughout America and the rest of the world range in age from hundreds of years old to brand new. They all have, however, one fact...

The Impact of Global Warming on Water Resources: Overview and Implications for Coastal California
In the past two years, impressive evidence has accumulated that global warming is occurring and is related to the increase in greenhouse gasses. The impact of the warming process on water...

Reservoir Management and Thermal Power Generation
Thermoelectric power stations on regulated rivers may cause violations in stream temperature standards if the dilution water from the upstream reservoir is not adequate. However, it is...

After the Blast
On February 26, 1993, a bomb exploded in an underground parking garage beneath the World Trade Center, killing six, causing hundreds of millions of dollars in damage and leaving a crater...

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....

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...

Formation of Kolkhida Shore During Sea Level Rise
A reconstruction of the Kolkhida coastline evolution during one of the thermal maximum in Holocene was made on the basis of geological data. These data are taken as a principle in calculation...

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...

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...

Development of Test Procedures for Unbalanced Head Operation of Slide Gates
This paper will discuss the steps taken by the Bureau of Reclamation to develop a standardized procedure for testing unbalanced head operation of high-pressure slide gates for outlet works...

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...
