Remediation Site Prioritization by the Risk Ranking and Filtering Method
The risk ranking and filtering (RRF) method, developed for ranking critical components of the NASA Space Shuttle, is a possible framework for the prioritization of hazardous-waste sites...
The Role of Risk Analysis in Feasibility Studies of Water Resources Projects
Many parameters involved in feasibility studies of water resources projects are inherently uncertain. Projections of these parameters based upon extension of past trends can be quite inaccurate....
The Use of Influence Diagrams in Risk Management Involving Multiple Stakeholders
In this paper, a new methodology is proposed that employs influence diagrams to integrate the issues that arise in risk management and to demonstrate the relationship amoung the stakeholders...
Optimal Allocation of Resources in Repair and Maintenance of Bridge Structures
The structural design process, examined in its entirety (and taking into account the uncertainty and randomness that characterize the governing parameters) is a decisional process, involving...
A Probabilistic Regional Damage Estimation Model for Earthquake Occurrences
In this paper we present a model for estimating regional earthquake damage. The model utilizes the relational data base management system ORACLE and the geographic information system ARC/INFO...
Probabilistic Evaluation of Redundancy of Bridge Structures
Redundancy of bridge structures and methods to evaluate redundancy are reviewed in this paper. A method to measure redundancy based on the existing theories of probability as related to...
Estimates of Extreme Wind Distribution Tails
The assumption that extreme winds have a Gumbel distribution appears to yield unrealistically high failure probability estimates for wind-sensitive structures. For this reason we study...
Fabric Related Probabilistic Model for Granular Materials
A new anisotropic noncoaxial incremental constitutive model for granular materials (Jahedi et al., 1990) was developed, in which a Fabric reconstruction factor '?+',...
Construction Loads on Floors: Results of a Survey
A survey of post-shorting construction loads on floors of multi-storey buildings is described. The estimated parameters of a probabilistic model of the peak (transient) loads are reported....
Risk Based Optimal Fatigue Testing
Optimal fatigue life testing of materials is considered. Based on minimization of the total expected costs of a mechanical component a strategy is suggested to determine the optimal stress...
Risk Based Structural Optimization
Risk based structural optimization problems for structural systems are formulated on basis of a so-called risk index. The risk index is defined as a consequence modified reliability index...
ASCE Review and Publication Process for Technical Journals
For many, the review and publication process for ASCE technical journals is not clear. Though the basic steps are outlined in the Authors' Guide, there are unwritten practices that may...
What Makes a Quality Paper?
A good paper is one that is easy for members of the intended audience to read and understand. It must contain an informative abstract. The introduction should include information on why...
Engineering of Controlled-Drainage Systems
Soil-water management by water table control (via a dual purpose subdrainage-subirrigation system) is becoming popular in humid regions of the U.S. and Canada. Controlled-drainage is an...
Degradation of Ground Water by Tetrachloroethylene
Ground water from many municipal water wells in California has been degraded by tetrachloroethylene (PCE) at concentrations above the drinking water standard. Investigations conducted...
Oklahoma's Ground Water Protection Strategy
This report examines Oklahoma's developing ground water protection strategy in light of the national strategy. We look first at relevant federal legislation and what EPA expects of a state...
Groundwater Management in Southern Florida
A water supply plan was developed by the South Florida Water Management District (SFWMD) for Hendry County, Florida as part of the Lower West Coast Water Supply Plan. In the course of...
Ground Water Management in Arkansas
Arkansas has historically enjoyed plentiful water and has typically resolved water conflicts with case by case application of common law. As agricultural, industrial and domestic water...
Evapotranspiration Data Management in California
This paper will discuss components of the California Irrigation Management Information System (CIMIS). CIMIS is an automated agricultural weather network operated by the California Department...
Predicting Water Quality as Affected by ET Using the Root Zone Water Quality Model
The Root Zone Water Quality Model (RZWQM) is a physically based simulation model used to predict water and solute movement running from, moving through, and leaching out of the root zone....
