Assessment of Safety Impacts of Highway Projects
In this paper the safety impact of highway improvement and maintenance activities is examined in terms of accident reduction potentials of these activities. There are three causes of accident:...

Innovations in the Design of Electrical Transmission Structures
New concepts are being advanced for the design of electrical transmission structures. The papers in this book cover the following: weather-element loading conditions, structural options,...

Landslide Investigations Using the Weight Penetrometer
The weight penetrometer is a light weight device and can be easily deployed on slopes not accessible to conventional exploratory tools such as drill rigs or cone penetrometers. The weight...

Parking Lot Gets White Top
The many-acre parking lot at the Valley Fair Mall shopping center in Salt Lake City, Utah is described. In 1985 the asphalt pavement was overlaid with concrete, making it one of the relatively...

Co-ordinated Microcomputer-Based Rain Data Network and Modeling Environment
A co-ordinated microcomputer controlled rainfall collection network has been designed which includes drop counting precipitation sensors, tipping bucket raingauges, Z80-A microprocessor...

Water Use by Saltcedar in an Arid Environment
Specialized instruments and measurement techniques developed at the University of Arizona facilitate precise estimation of evapotranspiration (ET) with the energy budget model. Use of...

North American Weather Modification Organizations
The objectives and purposes of most professional, technical and institutional organizations made up of people interested in weather modification as a tool in North American water resources...

Winter Highway Construction
The purpose of this paper is to describe a study of the feasibility of constructing highways in the wintertime in cold regions. The study, sponsored by the Alaska Department of Transportation...

Pavement Management Systems for Urban Areas
Pavements represent the largest public investment for most urban-area governmental jurisdictions. The magnitude of this investment requires that the expenditure of funds to maintain pavements...

Evaluation of Runoff Prediction Using Synthetic Rainfall and CREAMS
Of all the climatological data, rainfall is the variable to which a watershed responds most significantly. The amount and sequence of occurrence of rainfall are most important in the prediction...

Simulation of Airborne Snow Water Equivalent Measurement Errors Made over a Forest Environment
The Office of Hydrology of the National Weather Service has developed and maintains an operational Airborne Gamma Radiation Snow Survey Program in the upper Midwest (Peck, et al. , 1980)....

Computer-Assisted Grouting Evaluation Systems
Electronic monitoring of cement pressure grouting at Ridgway Dam provides a powerful tool for geologic assessment of drilling and grouting results. Graphic surveillance and analysis of...

Innovative Strategies to Improve Urban Transportation Performance
The field of urban transportation is facing some severe challenges. Roadways continue to deteriorate, the financial condition of public transit systems is abysmal, and general productivity...

Yakima Supervisory Real-Time Monitoring and Control System
The Yakima Remote Control System is a case study application of supervisory control and data acquisition (SCADA) concepts for the operation and monitoring of a large water resources project....

Characterization of Indoor Carbon Monoxide Levels Produced by the Automobile
Integrated air samples were obtained at seven small and six large service stations and two dealerships. These establishments were sampled during cold and warm weather operations for eight...

Modular Plastic Media for Shallow Bed Trickling Filter Applications
Little specific data is available for less sophisticated trickling filter systems which employ recent plastic media designs for shallow bed filters without the added cost of subsequent...

Rainfall Results of the Florida Area Cumulus Experiment and Their Implications for Drought Problems in the South
Evidence is presented for treatment effects during the Florida Area Cumulus Experiment (FACE). The sizes of the apparent effects are a function of scale, largest for the cell scale and...

Texas Hiplex?A Summary
Beginning in 1974, a new, concerted effort was undertaken by the Federal government, in cooperation with various High Plains states - including Texas - and local entities, to gain a better...

Texas Hiplex Experimental Design
Research into rainfall enhancement in Texas expanded rapidly during the 1970's with the Texas HIPLEX program. More recently, the states of Texas and Oklahoma and the United...

Evaluation of Cloud Seeding: Southern Great Plains
One of the important aspects of planned weather modification in the United States is that many operational, non-experimental cloud seeding projects have occurred since 1950. Further, several...
