The use of personal computers has become an indivisible part of the University of California at Berkeley (UCB) geotechnical testing laboratories. The University has been on the forefront...
Use of Computers for Soil and Rock Testing
The Bureau of Reclamation's central geotechnical laboratory in Denver, Colorado, routinely uses computers and associated electronic measurement devices for data acquisition,...
Use of Bar Code Technology to Simplify Sieve Analysis Data Acquisition
A system has been developed at the U.S. Army Corps of Engineers Ohio River Division Geotechnical Engineering Laboratory using bar codes and a computer coupled balance to aid in data collection...
Data Acquisition and Test Control in the Laboratory
With the progressive development of microcomputer technology, microcomputer based data acquisition systems have become an indispensable tool in the soil mechanics laboratory. This paper...
An Inexpensive Automatic Control System for Soil Testing
This paper describes an inexpensive automatic control system for soils testing. The system comprises a microcomputer, an analog to digital converter, a relay board, and solenoid valves....
Automation in Soils Testing Facility USAE Waterways Experiment Station
Automation is a powerful tool that when used intelligently can increase production, minimize cost, and improve production in any testing laboratory. The Soils Testing Facility (STF) at...
Spatial Variation in Liquefaction Risk Assessment
Basic concepts and methods of random field theory, needed to characterize 'distributed disordered systems', are reviewed and applied to a soil liquefaction case...
Foundation Evaluation of Barkley Dam for Seismic Analysis
An in-situ site investigation was performed at Barkley Dam, KY to gather essential information on the stratigraphy and nature of the foundation soils. From this information the site was...
Finite Element Analysis and Field Instrumentation of a Soil/Cement Arch
A two dimensional plane strain finite element analysis is used to predict the increase in stress on an existing tunnel caused by the addition of twelve feet of fill. The fill, soil/cement,...
Data Base of Seismic Body Wave Velocities and Geotechnical Properties
A data base of seismic velocities measured in soils and standard geotechnical engineering material properties has been established at the U.S. Army Engineer Waterways Experiment Station...
Effects of Hurricane Hugo On Water and Wastewater Systems of the Charleston Commissioners of Public Works
Hurricane Hugo had a major impact on the operations of the Charleston Commissioners of Public Works in their effort to provide safe water and wastewater service to their customers. Through...
Citizen Participation in Regional Planning Efforts
During the past 4 decades the formal role of citizens has become increasingly more apparent under changing legislative mandates. This paper examines citizen participation in developing...
The Dispersion of Ocean Outfall Plumes: Physical and Biological Dynamics
The discharge of municipal wastewater into the coastal ocean through large ocean outfalls is an important component in managing sewage wastes generated by heavily populated urban areas...
Moored Systems for Time Series Observations of Bio-optical and Physical Variability in the Coastal Ocean
Recently, multivariable moored systems (MVMS) have been developed to study the ecology and physics of the upper ocean. Concurrent MVMS measurements provide time series of beam attenuation...
Measurements of Nutrient and Metal Fluxes from the Sea Floor in the Area Around the Whites Point Sewage Outfall, Los Angeles, California
Studies are underway to determine the influence of sewage outfall-impacted sediment on the exchange of nutrients and trace metals in the coastal marine environment. Utilizing a benthic...
Regional Monitoring in Southern California
