Evaluation of the Pagosa Springs Geothermal Reservoir and Implications of Potential Additional Reservoir Development
The Town of Pagosa Springs is located 280 miles from Denver on the north bank of the San Juan River in southwest Colorado as shown on the Index Map, Some time before 1920 the first well...
Description of the Application of Goal Programming for Selective Withdrawal Structure Operation
Thermal stratification in reservoirs results in variations of water quality with depth. Selective withdrawal structures with outlets at different vertical locations, can be used to provide...
Effectiveness of Retrofit in Multi-Family Apartments
This paper reports the results of an evaluation research study of the cost-effectiveness of water-conserving, residential retrofit plumbing devices. By means of a 'quasi-experimental,'...
Simulating Hourly Hydropower Operations for the Assessment of Environmental and Economic Impact
Generation of peaking power at Glen Canyon Dam causes river flow and stage to fluctuate on an hourly basis. This has been shown to impact the downstream physical and biological environment....
Predicting Hydrologic Impacts of a Severe and Sustained Drought on the Colorado River Basin
We investigated the impacts of a severe and sustained drought (SSD) on the hydrology of the Colorado River Basin. The simulation was carried out using the Colorado River Network (CORN)...
Activity Based Costing in Water Resources Management
This paper examines the relatively new accounting tool, Activity Based Costing (ABC), and describes its potential application in water resources planning, management, and operations. The...
Technical Understanding in Successful Environmental Negotiations
Scientists at the National Ecology Research Center conducted a series of case studies of consultations concerning the environmental conditions to be included in Federal Energy Regulatory...

CAD for Small Hydro Projects
The quest to reduce design costs and improve design quality by raising productivity is familiar to every manager and designer. This article examines how CAD can play a role by examining...
Solar Stretch
Extrapolating from structural work with textile or metal membrane roofs to cover silos, assembly halls and sports stadia, Schlaich, Bergermann and Partners, a structural engineering firm...
Case Storage of Planning Knowledge for Power Plant Construction
Schedulers consider a variety of constraints when they analyze a project to schedule the construction work for it. Often they will start from some schedule that they recall from a previous...
Microworlds for Learning Through Inquiry
We discuss several computer-based environments to support learning through inquiry, called microworlds, including two focused on steam power plant operation and electronic troubleshooting....
An Interactive Computer Code for Generations of Artificial Earthquake Records
A new interactive computer code is presented in this work for the calculation of artificial earthquake records that comply with any arbitrarily specified target response spectra or power...
Field Test of Thermal Precompression
A new concept for improvement of soft ground using moderate heating to control post-construction settlement is presented. The long-term creep behavior of a peat is presented based on laboratory...
Rate of Settlement of Silt Alluvium at Trojan
Settlements of 1.83 m have been observed at the switchyard of the Trojan Nuclear Power Plant over a 22-year period since 1970. Rockfill had been placed on the site, a flood plain of the...
Recovery of Chromium from Spent Plating Solutions by a Chromyl Chloride Process
A novel chromyl chloride process has been investigated for the recovery of hexavalent chromium from spent plating solutions. In this process chromium is converted to chromyl chloride by...
Process Selection for Treatment of SOC Contaminated Waters
The most inexpensive method for treating synthetic organic chemical (SOC) contaminated wastewaters was studied. Air stripping, liquid-phase adsorption, fixed-film biological oxidation,...
Strain Measurement on the Runner of a Hydroelectric Turbine
Twelve strain gages were installed on the 10-m-diameter runner of Unit G-23 (700 MW) at Grand Coulee Dam, Third Powerhouse. The gages were located on both the pressure and suction sides...
Testing Turbine Aeration for Dissolved Oxygen Enhancement
During August of 1993 the Bureau of Reclamation tested turbine aeration for dissolved oxygen (DO) enhancement at Deer Creek Powerplant near Provo, Utah. This test required a variety of...
Pressure-Time Flow Rate in Low Head Hydro Plants
Very few methods are accepted for measuring the flow in the large intakes typical of low head, run-of-the-river hydro plants. These intakes are characteristically short, non-uniform, non-prismatic,...
