Seismic Engineering
Research and Practice
This volume of Seismic Engineering: Research and Practice contains papers from twenty-two sessions of the 1989 ASCE Structures Congress. These papers represent a wide-ranging interest...
Steel Structures
The seventy-eight papers included in this volume cover the fifteen sessions generally associated with steel structures presented at the Seventh Annual Structures Congress held on May 1-5,...
Adaptation of ANSI Standards for Communications Testing in the Connectionless Environment
American National Standards (X 3.102 and X 3.141) establish a uniform means for specifying, assessing and comparing performance of data communications systems and services from the point...
Incremental Risk Analysis in Teaching Institutions
Institutions engaged in research and teaching in the natural sciences, constitute a diffuse source of chemical emissions. As many institutions embark on ambitious building programs, communities...
Selective Calcium Removal for Water Softening
The paper reports on a 'Water Quality Control Study' for the City of Lafayette, Louisiana. This paper focuses on the laboratory phase of the project. The City...
A Practical Approach for Evaluating Environmental Risk
Risk management and assessment techniques are increasingly being used to project public health risks at hazardous wastes sites. Few studies have quantitatively evaluated the environmental...
Ft. Huachuca, AZ Fire Site Hazardous Waste Remedial Action
The paper discusses an investigation of the site of a major fire at Ft. Huachuca, Arizona. All of the fire debris contained asbestos. The sampling results confirmed that PCB levels of...
Technical Evaluation of a Copper:Silver Ion Swimming Pool Disinfection Unit
The paper reports on an investigation of a mock swimming pool setup on a laboratory scale. The study used indoor and outdoor simulated swimming pools to compare the efficacy of electrolytically...
Experimental Study of Windrow Composting of Sludge
An experimental field study of the windrow composition of sludge at the City of Dallas, Texas, Southside Waste Water Treatment Plant was conducted to provide data for possible design of...
Design of Solidified/Stabilized Sludge Landfills
Rehabilitation of highly moist, compressible, and heavy metal-containing wastewater treatment sludges for final disposal in a landfill setting requires consideration of several factors....
Sediment Processes and the Houston Ship Channel
A year-long field and laboratory study of sediment oxygen demand was conducted on the Houston Ship Channel. The primary objective of the work was to better understand the processes controlling...
In Situ Measurement of Preferential Flow
An experiment was performed that quantifies the variability of flow paths in the vadoze zone. Bromide tracer and an organic dye, which has many of the same transport characteristics as...
The Water Erosion Prediction Project: Erosion Parameter Estimation
The USDA Water Erosion Prediction Project (WEPP) includes a large field program for collection of experimental data to evaluate soil erodibility. Rainfall simulation techniques are used...
Input Processor Package for Water System Studies
An input processor package for a water distribution simulation model has been developed and field tested. This preprocessor enables users with little or no computer use experience to directly...
Storms and the Occurrence of a Turbidity Interface/Maxima in a Fresh Water Estuary
A combination of Landsat, field data and modeling analyses reveals a turbidity interface/maxima in the lower reaches of a freshwater tributary or 'estuary.' Mode...
Modelling Changes in Coastal Morphology
A description is given of a newly-developed coastal sediment transport model. Features of the model are the inclusion of cross-shore transport and non-potential suspended load, the latter...
Mid-Scale Laboratory Tests on a Two-Dimensional Movable-Bed Sand Model
A two-dimensional physical model was used to simulate wave-induced scour in front of a concrete dike sloped at 1:4. The tests were conducted at the U.S. Army Engineers Waterways Experiment...
Highly Concentrated Sediment Loads of the Yellow River
A set of high concentration data for the Yellow River in China is examined and compared with low concentration data and laboratory experimental results....
Alluvial Stream Bank Erosion?A 10-Year Study
Results of investigations of bank erosion along alluvial streams between 1977 and 1989 are given. Natural processes were found to dominate, with piping an important but hitherto unrecognized...
ASCE Task Committee on Analysis of Laboratory and Field Sediment Data Accuracy and availability
Alluvial channel observations for laboratory and field conditions have been collected throughout the twentieth century. These data have not been adequately evaluated as to accuracy or...
