Restricting Rockfalls
Predicting and controlling rockfalls has always been a high priority in Colorado, where many mountainous roads pass through hazardous rockfall areas with extensive and highly variable...

Tensile Terminal
Few can miss a fabric roof that covers a 1.45 million sq ft area. The one covering the Denver International Airport's Landside Terminal complex (reportedly the nation's...

Mechanical Excavator Performance in Yucca Mountain Tuffs
A research effort of four phases is in progress at the Colorado School of Mines. The overall program will evaluate the cutability of welded tuff and other lithologies likely to be excavated...

A First Look at Roadheader Construction and Estimating Techniques for Site Characterization at Yucca Mountain, Nevada
The Yucca Mountain site characterization program will be based on mechanical excavation techniques for the mined repository construction and development. Tunnel Boring Machines (TBM's),...

The Long Climb to Remediation
During World War II, the Rocky Mountain Arsenal in Colorado served as an Army manufacturing center for the production, then destruction, of mustard gas, napalm, cluster bomb mixtures,...

Estimating Power Plant Cooling Water Demand
The Fayette Power Project (FPP) includes three generation units, with more than 1,500 megawatts of generating capacity, supplying electricity to more than a million Central Texans. The...

Optimal Irrigation Planning for Drought Management in Lower Colorado River Basin
The Lower Colorado River Authority (LCRA) of Texas recently completed a Drought Management Plan (DMP) for the water supplies under its control. In developing that plan, the LCRA evaluated...

Integrating Water Conservation Into Water Supply Planning
Consideration of water demand reduction strategies is increasingly important in water resources planning. Although more research is needed to improve the reliability of water savings data,...

Use of Models in Water Resource Systems: CRSS Experience
The Colorado River Simulation System (CRSS) is an in-house governmental computer-based model designed to be used as a decision support tool in performing long and mid range planning and...

Managing Water Supply and Demand with Integrated Computer Models
Water resource planning and management has greatly benefited from the use of computer modeling. Numerous computer models have been developed to predict expected outcomes given a set of...

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....

Pumped Storage, the Environment and Mitigation
The privately financed 1,000 MW Rocky Point Pumped Storage Project located in central Colorado, USA, will be one of the world's highest head, 2,350 feet (716 m), reversible...

Glen Canyon Hydropower vs. The Grand Canyon (The Conflict of Basic Values)
Competing for the scarce resources of our future is the byword of the 1990's. For the last century and more, the United States has been in the position of always having more...

Cooperation and the Endangered Species Act
Passage of the Endangered Species Act (ESA) in 1973 set the stage for some of the nations most polemic environmental battles. One of these is in the Colorado River Basin which is home...

Varying Generator Excitation to Control Draft Tube Surge
The Bureau of Reclamation recently experimented with varying the excitation applied to a hydroelectric generator to control power swings caused by draft tube surging in a Francis turbine....

Validation Studies on Indexed Sequential Modeling for the Colorado River Basin
A method called indexed sequential modeling (ISM) has been developed by the Western Area Power Administration to estimate reliable levels of project dependable power capacity (PDC) and...

Implications of the 1987-1990 Droughts for Hydropower Generation at Reclamation Powerplants
Droughts in the western United States beginning in 1987 have caused water supply shortages and required rationing of water in some areas. The reductions in water supply have also impacted...

Assessment of Changes at Glen Canyon Dam
This paper describes the complexity associated with the assessment of financial impacts of proposed and actual short-term restrictions at Glen Canyon Dam. The reasons for these restrictions...

An Artificial Intelligence Approach to Multiple Reservoir Operation
The modeling of complex river basins using symbolic computer languages, object-oriented programming and knowledge-based reasoning facilitates, the application of optimization techniques...

An Improved Incremental Economic Dispatch Method for Hydroelectric Generators with Nonconvex Energy Production Cost Curves
The Bureau of Reclamation (Reclamation) has undertaken a program to improve water resource management at its hydroelectric powerplants. One feature of the resource optimization program...
