Aquifer Storage and Recovery at the Centennial Water and Sanitation District
water in a suitable aquifer, the peak time capacity of CWSD could be increased while delaying the water treatment plant (WTP) expansion currently scheduled for 1996. To validate this assumption,...

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)...

A Gaming Analysis of Drought-Coping Policy Options
Eight persons, representing the seven Colorado River Basin state and the Secretary of the Interior, managed a severe, sustained drought in the basin. The drought was portrayed by a simulation...

Economic Impacts of Severe and Sustained Drought
A hydrologic-economic-legal impact model shows that a severe and sustained drought in the Colorado River Basin would cause acute economic damages to most instream water users, and to upper...

The Law of the Colorado River: Can It Cope With Severe Sustained Drought?
This paper analyzes the Law of the River from the perspective of its effect on allocation decisions in the event of a long term, severe drought. The analysis is organized in a manner familiar...

Denver's Direct Potable Water Reuse Demonstration Project
The Denver Potable Water Reuse Demonstration Project was created to provide definitive answers to the interrelated questions of product quality, public health, technical and economic feasibility,...

Potable Water Reclamation—A Practical Option to Traditional Sources
This paper describes the development of potable water reclamation alternatives to meet the future municipal water needs of the City of Colorado Springs, Colorado. By the year 2042, the...

Reusable Water Exhange Modeling
Wastewater return flows of raw water which is reusable, i.e., water which is entirely consumable, can be exchanged for a like amount of water upstream in the river basin. Exchanged water...

A New Approach to Water Education: Children's Water Festivals
A number of Colorado water agencies, school districts, and municipal utilities have combined efforts recently to coordinate a relatively new concept in water education - Children's Water...

Conservation Before and After: The Impacts of Increasing Block Rates on a Fully Metered System
Denver Water's inside residential consumption and revenues changed dramatically during a metering program and a conversion to inclining block rates. We analyze these two changes and make...

Hydraulic Analysis of the Water Distribution System, Vail Valley Consolidated Water District, Vail, Colorado

Compaction Grouting Stops Settlement of an Operating Water Treatment Plant
In early 1978, about a month into full-time operation, the new filter plant building for the water treatment plant for the City of Glenwood Springs, Colorado, experienced distress due...

Laboratory and Field Evaluation of Acoustic Velocity Meters
A project is currently underway to evaluate the performance of 27 acoustic flowmeters used at Hoover, Davis, and Parker Dams on the lower Colorado River. Field surveys and laboratory testing...

Effects of Particle Shape on Bedload Transport
The effects of particle shape on bedload transport in gravel-bed streams are examined using a similarity approach and fractional transport analysis for data from Piceance Creek, Colorado,...

Hydraulics and Sediment Transport Processes in a Pool-Riffle Rocky Mountain Stream
Sediment transport processes related to varying channel-bed morphology were investigated from April to November, 1993 along a 1 km pool-riffle and step-pool reach of North Saint Vrain...

Coarse Sediment Transport and the Maintenance of Fish Habitat in the Upper Colorado River
An analysis of the relation between discharge and boundary shear stress is presented for an alluvial reach of the Colorado River near Grand Junction, CO. The analysis indicates that the...

Historic-Flood Evaluation and Research Needs in Mountainous Areas
An evaluation of historic flood estimates in mountainous areas in Colorado was made to assess their accuracy. The purpose of this evaluation is to enhance awareness of the need to assess...

Bed Material and Numerical Modeling in a Gravel/Cobble Bed Stream
The characteristics of bed material in a cobble or gravel river and their use for numerical simulation of flushing flow needs are discussed. There are three types of bed material: 1) material...

Deicing Denver
Glycol-based deicing fluids are an essential part of winter operations at most airports. While these chemicals help ensure safe and timely aircraft operations, stormwater runoff contaminated...

Let's Go to the Videotape
Illustrating a design concept to educate and soften the resistance of community groups, environmentalists, government regulators and funding agencies is not a new idea. But the state of...
