Capitol Reef Wilderness Study, United States Deparment Of The Interior, National Park Service Dec 1973

Capitol Reef Wilderness Study, United States Deparment Of The Interior, National Park Service

Elusive Documents

Capitol Reef National Park is located in south-central Utah within

portions of Wayne, Garfield, Sevier, and Emery Counties. Situated on

the western edge of the Colorado Plateau, this scenic land is adjacent to

Dixie and Fishlake National Forests and Goblin Valley State Park.

Other Park Service areas nearby include Zion and Bryce Canyon

National Parks, and Cedar Breaks National Monument to the west;

Canyonlands National Park and Arches National Park to the east; and

Glen Canyon National Recreation Area to the south and east.


Mathematical Simulation Of Temperatures In Deep Impoundments: Verification Tests Of The Water Resources Engineers, Inc. Model - Horsetooth And Flaming Gorge Reservoirs, Engineering And Research Center, Bureau Of Reclamation Nov 1973

Mathematical Simulation Of Temperatures In Deep Impoundments: Verification Tests Of The Water Resources Engineers, Inc. Model - Horsetooth And Flaming Gorge Reservoirs, Engineering And Research Center, Bureau Of Reclamation

All U.S. Government Documents (Utah Regional Depository)

Successful use of predictive mathematical models requires verification of the accuracy of the models by applying them to existing situations where the prediction can be compared with reality. A Corps of Engineers' modification of a deep reservoir thermal stratification model developed by Water Resources Engineers, Inc., was applied to two existing Bureau of Reclamation reservoirs for verification. Diffusion coefficients used for the Corps' Detroit Reservoir were found to apply to Horsetooth Reservoir in Colorado, for which very good computer input data were available. The Detroit diffusion coefficients gave a reasonable simulation of Flaming Gorge Reservoir in Wyoming and Utah, which …

Protection Of Our Fragile Upper Atmosphere, Clayton Clark Jan 1973

Protection Of Our Fragile Upper Atmosphere, Clayton Clark

Faculty Honor Lectures

Termination of U.S. government support for the Supersonic Transport, SST, may eventually cost the United States its leadership in aviation and billions of dollars in international trade losses, yet if the world wide SST program is allowed to continue, the costs to mankind as a result of damage to environmental resources could be much higher. The decision to terminate the project was heavily based upon concern for possible changes in the properties of the upper atmosphere as a result of SST operations in that realm, with consequent danger to plant and animal life on the Earth below. Briefly, the concern …
