The Area of Most Recent Volcanism Near Yucca Mountain, Nevada: Implications for Volcanic Risk Assessment
The proposed area of most recent volcanism (AMRV) includes all known post-6 Ma volcanic complexes in the Yucca Mountain area and encompasses the four volcanic centers in Crater Flat, the...

Tucson, Arizona's 110-Year Water Resources Plan
The desert community of Tucson, Arizona, has just completed a state-mandated 110-year water supply plan. The plan includes conjunctive use of local groundwater and surface water imported...

The Use of the IWR-Main System as a Planning Tool in Phoenix, Arizona
The IWR-MAIN water demand forecasting model is used extensively as a long-range planning tool by the Phoenix Water and Wastewater Department. Its specific applications include: conservation...

A Computerized Hazardous Material Incidents Database
This paper reports on the development of a microcomputer database management system for hazardous material incidents that occurred on highways and at fixed sites in Arizona. The objective...

Interfacing Pavement Management and Design Process
Pavement management systems coordinate all the activities required to provide pavements for the traveling public in a cost efficient manner. Information for the pavement management system...

Simulating Runoff and Sediment Yield on Semiarid Watersheds
This paper describes a computer program called WESP (Watershed Erosion Simulation Program), a physically-based, distributed parameter, event-oriented, one-dimensional numerical model for...

A Comparison of Runoff and Sediment Yields from Bare and Vegetated Plots Using Rainfall Simulation
Data from 108 small plot rainfall simulator experiments on pinyon-juniper woodlands in Arizona and New Mexico were analyzed to determine quantifiable effects of cover on hydrologic and...

Management of Groundwater Overdraft in the Phoenix, Arizona, Area
By law, the overdrafting of groundwater in the Phoenix, Arizona, area must cease by the year 2025. Safe yield can be achieved by means of conservation, water supply augmentation, and condemnation...

Optimizing Wet-Dry Precipitation Probabilities for Improving Plant Establishment
Studies have shown that the chances of achieving successful seedling establishment in arid and semiarid regions is dependent upon the pattern of favorable wet-dry precipitation sequences....

Maricopa County Hydrology Procedure
The Flood Control District of Maricopa County has developed a procedure to be used for flood hydrology in Maricopa County, Arizona, and the Flood Control District has prepared a Hydrologic...

Rainfall Simulation Studies of Nutrient Export from Watersheds in Arizona and New Mexico
Data from rainfall simulation experiments conducted in Arizona and New Mexico were used to identify relationships between total suspended sediment (TSS) concentrations (kg/ha/mm of runoff)...

ROTO—A Continuous Water and Sediment Routing Model
A model called ROTO was developed to estimate water and sediment yields on large basins (several thousand square miles). ROTO is a continuous model operating on a daily time step that...

Near Real Time Irrigation Scheduling Using Heat Unit Based Crop Coefficients
An interactive computer program (SCHEDPEN) which utilizes growing-degree-day based crop coefficients for irrigation scheduling was developed and tested on cotton during 1988 and 1989 at...
