Trash Busters ? A Comparison of Screening Structures for Irrigation Systems
Several irrigation districts in the Pacific Northwest have recently installed screening structures for use in removal of trash from canals, rivers, or reservoirs. Some of the screens have...
Fate of Chemical Contaminants in Soil
Soil as a medium for storage, attenuation, immobilization, or degradation of chemicals has not provided the capability and protection of resources that was predicted in past fate studies...
Evolution of Water Organisations in England and Wales
Although by the early 1960's there was in existence a large body of legislation dealing with water matters, the Water Resources Act 1963 provided for the first time a significent...
Water Supply and Sewage Disposal: Shanghai, China
This paper describes a joint research effort which took place between the Shanghai Bureau of Environmental Protection, Tsinghua University (Beijing), and the University of Michigan. The...
Design Criteria for Mass Culturing Spirulina Algae
One extract of Spirulina, developed by Dr. Christopher Hills has been used as a nutrient for cell cultures and contains a growth factor called Spirulina Growth Factor. Another extract...
Top Projects of 1986
In the 1986 ASCE competition to select the Outstanding Civil Engineering Achievement of the Year, 14 projects were nominated. This article describes the 10 non-winners. Technically the...
Environmental Engineering
Over 80 of the papers presented at the 1986 National Convention on Environmental Engineering are included in this book. The major categories covered include air, noise, and radiation management,...
Infrastructure in a Hurry
The City of Austin, Texas has experienced tremendous growth since the early 1970s. Until recently, however, infrastructure development lagged. Now the city is engaged in a $1 billion infrastructure...
Behavior of Concrete Bulkheads in Salt Drifts
Parameters studies of the behavior of a plug made from expansive concrete have been performed. Such plugs are now being field tested for sealing boreholes, shafts and drifts at an underground...
Structural Design of the Defense Waste Processing Facility
The Defense Waste Processing Facility (DWPF) is designed to process radioactive defense waste sludge and the radioactive nuclides, cesium and stronium, from the salt solution. These radioactive...
A Generic Design for On-Site Low Level Radioactive Waste Storage
This paper describes a generic design for an on-site low level radioactive waste storage facility. The generic design encompases the development of design criteria including an envelope...
Building Arrangement and Site Layout Design Guides for On Site Low Level Radioactive Waste Storage Facilities
This paper will discuss a typical storage facility and address the design considerations and operational aspects that are generally overlooked when designing and siting a low level radioactive...
Nonlinear Analytical Models for Interfacial Plug Stresses in Creeping Salt Formation
Analytical and numerical simulation models are presented which predict the nonlinear time dependent behavior of an expanding plug in a creeping environment heavily dependent on the storage...
Passing the Public Works Buck
Users and beneficiaries of local and state public works projects are paying a larger share of their cost. State and federal grants and general local revenues are being relied on less....
Water Forum '86
World Water Issues in Evolution
These proceedings for Water Forum '86 include papers presented at the second conference in which the water-oriented divisions of the American Society of Civil Engineers have...
Conference Overview
An Engineering Foundation Conference organized by the ASCE Urban Water Resources Research Council was held at New England College in Henniker, New Hampshire, June 22-27, 1986. This paper...
Lognormality of Point and Non-Point Source Pollutant Concentrations
This paper presents a series of probability plots of water quality data from a variety of discharge sources. It is intended to provide a visual display of the appropriateness of characterizing...
Bridging the Joints in Bridges
Most bridges are designed with gaps in them. The cracks allow bridges to expand and contract as the temperature changes. But water can enter these gaps and foul bearings and structural...
Constructing a Better Environment
The civil engineer is traditionally designated the jobsite environmental engineer during construction, and is responsible for managing environmental protection and monitoring. Jobsite...
New Runways Take Off
The two mile long runway 9-27, now being constructed at Houston Intercontinental Airport, was built for about 30% ($7 million) less than if designed conventionally. Rather than concrete...
