Oil Spill Detection by NOAA/AVHRR on Persian Gulf
An area of oil spills on the Persian Gulf was detected by the thermal-infrared channels of Advanced Very High Resolution Radiometer (AVHRR) on NOAA-7. AVHRR gives the temperatures of the...

Hydraulic Fill Dam Made Earthquake Resistant
San Pablo Dam, near the San Andreas fault, constructed in 1919-21 by hydraulic fill methods, was found to be susceptible in places to liquefaction under seismic loading. The dam has been...

Project Mixes Oil and Water
The Prudhoe Bay Seawater Treatment Plant was nominated for an OCEA award, for its potential to coax from Alaska's north slope 1 billion barrels of oil which otherwise would...

Construction-Induced Dynamic Pressure and Corresponding Impact Factors for Pipelines
The Bureau of Reclamation, U. S. Department of the Interior, conducted a study which measured pressure exerted by construction scrapers on a rigid, buried, instrumented concrete slab....

Effects of Vehicles on Buried, High-Pressure Pipe
The mechanical effects of selected types of traffic on buried, high-pressure steel pipe are examined. Particularly considered is a section of the Colorado Interstate Gas (CIG) pipeline...

An Instrumented Soil-Pipe System: Automated Data Acquisition and Management
A 16-in. natural gas pipeline near Racine, Wisconsin, had been in service for some 30 years. In 1982 road widening operations on a line parallel with the pipe resulted in a heavily trafficked...

Failure of a Large Reinforced Concrete Pipeline
This paper describes the damage that occurred when a landslide overloaded an 11 ft diameter reinforced concrete pipeline. The 8 ft lengths of pipe, each of 11. 5-in. wall thickness, were...

Field Burial Tests of Corrugated Double Wall PVC Pipe
A new lightweight PVC pipe, consisting of a smooth inner wall and a corrugated outer wall, has been introduced in the U. S. sanitary sewer market in 4 through 10 in. diameters. Field burial...

Earth Pressure and Surface Load Effects on Buried Pipelines
Rational techniques for analyzing earth pressure and surface load effects, based on finite element analysis methods, have been developed and applied extensively to the design of buried...

Strains Induced by Combined Loading in Buried Pressurized Fiberglass Pipe
In 1983 Owens Corning Fiberglas and Utah State University collaborated on a study of combined strain behavior of fiberglass pipe to quantify the bending strain reduction as a function...

Long Term Testing of Centrifugally Cast Glass Fibre Reinforced Plastic Pipes (RIRP)
The paper discusses testing of pipe manufactured by centrifugal molding. The tests included external load tests, internal load, hydrostatic internal pressure, and cyclic internal pressure....

KEMCOR?A Chemical and Corrosion Resistant Piping System
KEMCOR is a new underground composite pipe system designed for chemical process use in such industries which require a high degree of corrosion resistance to varying concentrations and...

Field Testing of 84-Inch-Diameter Plastic Pipe
During the summer of 1981, a research project was initiated to monitor strains and deformation in 84-inch diameter RPM (reinforced plastic mortar) pressure pipe. Three 20-foot (6. 1-m)...

Successful Use of Centrifugally Cast Glassfiber Reinforced Plastic (GRP) Pressure Pipes for Public Works in Sweden
Centrifugally cast GRP pipes were introduced in Sweden 17 years ago for industrial applications mainly as a gravity pipe. The process of pipe manufacturing as well as the pipe itself and...

Design of Non-Pressure Very Flexible Plastic Pipe
There is considerable debate about the correct structural design procedure to be used for very flexible plastic pipe (VFP) - typically glass-fiber reinforced pipe (GRP), reinforced plastic...

Influence of Frost Action on the Load Exerted on Buried Pipe
When work was started on revising the Swedish code for concrete pipes at the end of the 70's, a research project was carried out to evaluate the risk of increased load due...

Integrated Hydrothermodynamic Study of Browns Ferry Nuclear Plant
The results of hydrothermodynamic analyses and computer models discussed in previous papers are combined to present an integrated study supporting a request for alternative thermal limits...

Boundary Shear Stress in a Meandering Channel
Longitudinal and transverse velocity, bed shear, and water surface elevation were studied in a fixed-bed, meandering, laboratory channel with naturally varying, non-prismatic cross sectional...

Computer Simulation of Coagulation
Coagulation, the process of collision and coalescence of particles, modifies the size distribution of the suspended mass, continuously creating larger particles which may settle out of...

Particle Sizes in Flocculation and Sedimentation: Models and Experiments
D. F. Lawler et al. developed a model for flocculation, sedimentation, and filtration and predicted the effects of particle size distribution and concentration of the influent in water...
