Alyeska Reroutes Trans-Alaska Pipeline at MP 200
This paper discusses the 1985 wintertime repair/reroute to the Trans Alaska Pipeline System (TAPS). The rerouted pipe was approximately 4000 feet long and cost approximately 27 million....

Wastewater Plant Cold Weather Operational Problems
A questionnaire survey was conducted at biological wastewater treatment facilities in northern New England. Problems associated with various unit processes, due to cold weather operations,...

Legal Concerns in Cold Regions Engineering and Construction
For a variety of reasons the potential for the imposition of liability and the potential for comparatively large damage claims is greater in cold regions. It is the purpose of this paper...

An Expert System for Flood Estimation
This study was made to investigate the feasibility of expert systems for solving certain engineering problems. A prototype system was developed to demonstrate the applicability of these...

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,...

Superminis for Super CAD
Many second time users of computer-aided design software and hardware, in their efforts to have more power and flexibility, are switching to superminicomputers and building their own systems....

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...

Studies of Long-Term Water Losses
The water-loss time series are formulated for the studied watersheds in the Ohio River Basin through the use of the law of water balance to the system inputs and corresponding outputs....

An Expert System for Snowmelt Runoff Modeling and Forecasting
An expert system has been designed and is being built for predicting snowmelt runoff. The expert system mimics an experienced hydrologist by assisting the user in preparing data input,...

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...

Real-Time Monitoring and Flood Forecasting
An automated flood warning system is now serving the 2,700,000 residents of Houston, Harris County, Texas. Real-time rainfall and river level data from more than 150 sensors are automatically...

Computer Aided River Basin Management in the Alps
The present paper outlines progress in developing river basin management potential through joint research on several Alpine River Systems including the Avisio, Brenta, and Cordevole. Applications...

Simulation Models of Sequences of Dry and Wet Days
A new statistical model has been developed for the simulation of sequences of dry and wet days. The model is based on the discrete autoregressive-moving average (DARMA) family of stochastic...

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...

Instant Hydro Forecasting
Two new software programs developed by a San Francisco-based engineering firm determine hydropower potential, best site configuration, and best economics for hydroelectric projects. One...

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...

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...

Predicting Forest Snow Water Equivalent
In California, the snowpack of the Sierra Nevada provides more than one-third of the state's water needs. Regression models used to forecast this supply do not include measurement...

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)....
