Bartlett Dam Fuseplug Auxiliary Spillway
Bartlett Dam is located approximately 77 km northeast of Phoenix, Arizona on the Verde River. The Bureau of Reclamation (Reclamation) has determined that the structure is not capable of...

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...

Variations Encountered in Design Analysis of Local Scour at Drop Structures
Proper design of drop structures can prevent failure due to scour at upstream structures, like bridges. An important aspect of drop-structure design is the prediction of the local scour...

Riprap Design at Bridges–Factor of Safety Approach
The factor of safety method offers a physically based methodology for design of riprap that relates the applied shear stress on the channel boundary to the stability of the riprap layer....

Scour Retrofit Case Studies for Arizona
Scour retrofit involves a coordinated analysis and joint determination of action by several engineering disciplines: typically, geotechnical, hydraulic and structural engineering. The...

Field Testing of Advanced Maintenance Data Acquisition Technologies in Three State DOTs
Field testing and evaluation of advanced data acquisition technology in Maryland, Connecticut and Arizona showed the potential for state highway agencies to improve existing procedures...

Overland Flow Resistance Estimation from Small-Plot Data
The correct application of physical process models, such as the kinetic wave approximation to shallow overland flow, is dependent upon selection of appropriate values for parameters which...

Evaluation of Plants for Coastal Dune Stabilization
The dune stabilization system used in the Phoenix Condominiums project can be used to enhance dunes all along the Atlantic and Gulf Coast. The plants and technology are available, which...

Impact of Groundwater Management Act and CAP Water Supply on Agricultural Water Conservation Programs
Irrigation districts in central Arizona have increased the tax assessments for their farms to pay for distribution systems to deliver Central Arizona Project (CAP) water. Many farms must...

The Use of Post-Tensioned Anchorages on the Arch Portion of Stewart Mountain Dam, Arizona
Post-tensioned rock anchorages were selected by the Bureau of Reclamation (Reclamation) to stabilize Stewart Mountain Dam against potential seismic loadings. The use of such anchorages...

Modeling Adsorption of Mixtures of Radionuclides by Zeolitized Tuff
Multi-solute sorption isotherms were measured using 'nonscents', a zeolitized volcanic tuff material from Southeast Arizona. Isotherms for the three constituent binaries, Sr-Co, Cs-Sr...

Coolidge Dam Abutment Stability and Stabilization
This paper focuses on left abutment stability assessments and stabilization measures at Coolidge Dam, Arizona. Initial assessment of abutment stability was based on limited rock strength...

Siting Agricultural Weather Stations
Studies were conducted in Arizona and Washington to investigate how the surrounding fetch affects data collected by agricultural weather stations (AWS). AWS surrounded by extensive areas...

Alluvial Fan: Subset Definitions
The Flood Control District of Maricopa County, Arizona recently completed a study whose goal was to identify and describe four alluvial fans for instrumentation and long-term monitoring....

AZSCHED—Software for Real-time Irrigation Scheduling
A user-friendly computer based scheduling program was developed to minimize the amount of data which needs to be input by the user by utilizing a network of twenty automated weather stations...

Cost-Benefit Evaluation of Network Level Pavement Management
This paper presents a cost-benefit analysis prepared for senior management. It uses the Alberta pavement management system as the primary case, and the Arizona PMS system as the second...

Performance of Recycled Asphalt Concrete Materials in an Arid Climate
Recycling of asphalt concrete pavement is a common practice for highway agencies. In 1981, the Arizona Department of Transportation (ADOT) constructed eight test sections in on experimental...

Monitoring of Highway Pavements in Arizona Using Falling Weight Deflectometer

Mechanical Properties of Compacted Lunar Simulant Using New Vacuum Triaxial Equipment
Mechanical stress-strain-strength properties of Arizona Lunar Simulant (ALS) are investigated by using a newly developed vacuum triaxial device that allows compaction under different initial...

Arizona's Uniform Traffic Impact Procedures
This paper discusses the development of policies and detailed uniform guidelines for traffic impact analysis of proposed developments along Arizona State highways. The paper addresses:...
