Streamflow Depletions Considered in Water Transfers
In the State of Colorado, streamflow depletions are defined as that amount of water diverted to beneficial use minus return flows to the stream system. This paper summarizes the engineering...

Water Transfer: Applicants and Objectors Analyses
Two different analyses of the historical on-farm consumptive use and return flows of agricultural water rights in Northern Colorado are discussed. The City of Thornton plans the transfer...

Evapotranspiration of Dry Beans with Drip Irrigation
Information about the effect of irrigation on dry bean production in the Southwestern Colorado is very limited. The primary objective of this study is to establish a crop water use (ET)...

Pioneer Highway
The 1993 Outstanding Civil Engineering Achievement Award goes to the $490 million I-70 Glenwood Canyon in Colorado. The final link in Interstate 70 from Baltimore, Md. to Cove Fort, Utah,...

Debris Flows in Grand Canyon National Park, Arizona: Magnitude, Frequency and Effects on the Colorado River
Debris flows are recurrent sediment-transport processes in 525 tributaries of the Colorado River in Grand Canyon. Arizona. Initiated by slope failures in bedrock and (or) colluvium during...

Variation of Froude Number with Discharge for Large-Gradient Streams
Under chemical-control conditions, the Froude number (f) for a cross-section can be approximated as a function of the ratio R2/ 3/d...

Prediction of Gravel Transport Using Parker's Algorithm
This paper demonstrates that sediment discharge in gravel streams can be reasonably estimated by calibrating the Parker and Klingeman procedure. This paper also identifies the need for...

Differentiation of Debris-Flow and Flash-Flood Deposits: Implications for Paleoflood Investigations
Debris flows and flash floods are common geomorphic processes in the Colorado Rocky Mountain Front Range and foothills. Usually, debris flows and flash floods are associated with excess...

Denver International Airport AGTS—A Progress Report
Denver International Airport (DIA), the first major airport to be built in the United States in nearly 20 years, is under construction approximately 25 miles (40 km) northeast of downtown...

Initial Planning and Implementation of the Telluride Gondola Transit System
Construction on the first phase of a gondola transit system began in the summer of 1992, with the goal of connecting the town of Telluride, Colorado with the Telluride Mountain Village,...

Traversing the Terminals
When it opens this December, the Denver International airport will rely on an $89 million automated-people-mover, (APM) system as the primary means of transporting passengers between the...

Side Resistance of Drilled Shafts in the Denver and Pierre Formations
Results of load tests on drilled shaft foundations in Upper Cretaceous shales are described and evaluated. Three load tests were conducted on shafts in the Denver Formation, in Denver,...

Keller Canyon Fills a Need
Opening a new landfill site in California can be an onerous task. Any owner willing to try must work with the state's stringent environmental legislation, profusion of solid...

Designing Reinforced Rock
The reinforced rock arch design method has been used to stabilize coal mine excavations for 40 years, but so far has been applied to only a few tunnels. The use of rock reinforcement develops...

Simulation of Reservoir Operation Using Smart Reservoirs

Extraction of Potable Water from Urine for Space Applications
A regenerative technology capable of managing water and wastewater on-board long-term manned space platforms is essential if the Bush Administration's Space Exploration Initiative (SEI)...

A Pilot Sounding Rocket Project Utilizing Student Labor
Space science experiments have been accomplished by suborbital, sounding rockets for over forty years. This inexpensive, reliable, and unique launch platform provides the basis of a state-wide...

Fine Tuning the Airfield: The New Denver International Airport
This paper discusses airfield layout considerations that have been incorporated into the design of the new Denver International Airport (DIA). These concepts include some unique provisions...

Aircraft Noise Monitoring at Denver International Airport
This paper describes design of the noise monitoring system for Denver International Airport. When the airport opens in 1993, the system must monitor compliance with two standards established...

City and County of Denver Approach to Management Requirements
Construction of large infrastructure projects has become increasingly rare since the 1960's. In fact, America has not built a new airport since 1974. While sparse funding is certainly...
