Description
The goal of this project is to investigate the hydraulic efficiencies of Type 13 (bar inlets), Type 16 (vane inlets), and Type R (curb-opening inlets) for street and roadway drainage. Although these inlets have been widely used in many metropolitan areas, the design empirical formulas and coefficients have not been verified.

Description
Questa Engineering Corporation has prepared a basin-wide coalbed methane reservoir model of the Colorado portion of the San Juan Basin. The model simulates the effects of production from all existing and proposed Fruitland coal wells in Colorado. The effects of dewatering, gas adsorption and desorption, and historical production are included in the model. It also provides a technology to evaluate coalbed methane infill drilling and gas seepage at...

Description
HDPE pipes used in CDOT drainage systems are expected to have a 50-year design life. During the T-Rex project in 2003 a number of HDPE pipes were installed with shallow cover. Later, the majority of these pipes had to be removed and replaced after they were damaged by construction equipment driving over installed pipes, and excavations occurring near installed pipes. In this study, performance of HDPE pipes under CDOT highways was evaluated by: an...

Description
A new service life chart for steel pipes was developed based on the information collected from the field observations and data analysis. Pipe failure criteria were established in accordance with the ongoing culvert evaluation procedure along I-70 and I-25. For the steel pipe failure cases along I-70 and I-25, the previously published service life predictors for steel pipes deviated from observations by as much as 10 times.

Description
A basin-wide coalbed methane reservoir model of the Colorado portion of the San Juan Basin. This model, which is referred to as the 3M CBM MODEL, simulates the effects of production from all existing and proposed Fruitland coal wells in Colorado. The effects of dewatering, gas adsorption and desorption, and historical production are included in the model. The 3M CBM MODEL provides a tool to evaluate the effects of coalbed methane infill drilling and...
37) Greenhouse gas neutrality assessment of coal mine methane and waste-to-energy pyrolysis projects
Pub. Date

Description
Colorado's Renewable Energy Standard (RES) has been in effect since 2004, but in 2013, coal mine methane (CMM) and synthetic gas produced by pyrolysis of municipal solid waste (MSW) were added as eligible energy resources as long as the renewable energy projects are greenhouse (GHG) neutral. The purpose of this study was to develop a framework for project developers and the Colorado Public Utilities Commission (PUC) to assess the GHG-neutrality of...

Description
"Inter- and transdisciplinary examination into the 2015 Gold King Mine spill in Silverton, Colorado, when three million gallons of subterranean mine water, carrying 880,000 pounds of heavy metals, spilled into a tributary of the Animas River. Illuminates the ongoing ecological, economic, political, social, and cultural significance of a regional event." --
