Unit Operations Approach in Exposure/Release Evaluation for New Chemicals
The unit operations approach may also be applied to the estimation of potential exposure and release of toxic materials from the manufacture and/or processing of new chemicals. By characterizing...
Health Effects,Risk Assessment and Guidance for Indoor Radon
Unlike many inorganic elements, radionuclides have no nutritional value. Radionuclides are carcinogenic and uranium is also known to be non-carcinogenic as well. This paper is primarily...
Responsibility/Liability Related to Mudflows/Debris Flows
The combined experiences of the authors during the past few decades indicate that many of the problems and losses related to damage from floods, landslides, mud/debris flows, and water-related...
Facilities Planning in the Caribbean a Case Study
Culebra has significant problems of water scarcity and poor wastewater treatment. In 1984-1985, a formal Environmental Impact Statement (EIS) was prepared for improved wastewater treatment...
Effect of Baghdad City Sewage Treatment Effluents on Dissolved Oxygen Profiles of an Iraqi River
The paper presents measured dissolved oxygen (DO) profiles in an Iraqi river in the vicinity of Baghdad City. The effect of the effluent discharges from Baghdad Sewage Treatment Plant...
Response of the Citanduy River to Developments
The sinuous alluvial reach of the Citanduy River in Java, Indonesia has been surprisingly stable in spite of man-made cutoffs which have reduced the channel length from 98. 7 km to 78....
Implications of Nitrogen Transport by the Okanagan River
The long-term mean of total nitrogen load estimated in the river channel above the inlet to Skaha Lake is 906 lb day** minus **1. The apportionment of ammonia and nitrate plus nitrite...
Ground Water Strategy in California
There is great debate over when and how much new water California needs. Yet of the backbone supply, wells that could serve over 1 million people have been either removed from use or blended...
Policy Issues in Managing Nonpoint Source Pollution
Attention is first given to the extent of the right of the landowner to generate contaminated runoff. The previously recognized privilege of landowners to make point source waste discharges...
Utopia Under Glass
We stand within sight of the day when our reserves of fossils fuel will be inadequate to maintain the type of energy inefficient cities we have grown used to. This exercise in urban planning...
Earthwork and Resource Estimation on Large Expedient Projects
A computer-aided technique is being developed for planning, design, estimating, and scheduling of horizontal construction for facilities required to support military operations. This technique...
Alterations to Old Wood Building
In order to accommodate a new use, a request was made to remove bearing walls supporting the roof of a 42 year-old building and substitute timber posts. The existing nine-foot ceiling...
Seismic Risk Analysis of a Multi-Site Portfolio of Buildings
A discussion of a methodology that permits the assessment of the seismic risk associated with a group of buildings and incorporates relevant aspects of seismic hazard assessment including...
Lessons Learned from Design, Construction, and Performance of Hydraulic Structures
The intent of this publication is to provide lessons learned, both positive and negative, from activities associated with design, construction, and performance of hydraulic structures....
Seismic Design of Braced Steel Frames
Seismic behavior of a six-story, K-braced structure without backup ductile moment-resisting frames designed according to the current Uniform Building Code is studied in this paper. The...
Study of the Collapse of a Reinforced Concrete Model Structure Under Simulated Earthquake Motion
The collapse, under simulated earthquake motion, of a multistory r/c frame structure with columns flexurally weaker than beams (SBWC) is studied. A small-scale model, comprising parallel...
Water Project Design and Safety: Prospects for Use of Risk Analysis in Public Sector Organizations
After offering some initial definitions, the authors will describe a highly structured model of risk analysis and water resources decision making in the public sector. The primary emphasis...
Approaches to Acceptable Risk
Acceptable risk has numerous meanings, that are derived from its having been defined in multiple arenas and by multiple groups. This paper describes several approaches to the question...
The Credibility of Probabilities: An Application to Water Resources Policy
This paper focuses on one particularly troublesome issue in decision analysis, the issue of the credibility of subjective probabilities. A water resources policy problem is used to illustrate...
