Damage Accumulation Models for Bridges
In the study summarized in this paper the serviceability and ultimate limit states were reviewed for concrete and steel girder bridges. A model is proposed to evaluate strength and remaining...
Reliability Analysis of Single-Headed Anchor Bolts
Several design equations for predicting the capacity of single-headed anchor bolts embedded in plain concrete have been recommended in the United States. The capacities predicted by these...
Stochastic Risk Assessment for Structural Safety
Through the United States the structural safety of major and/or innovative structures has become a serious concern for engineers and to the general public. The objective of this paper...
Bayesian Updating of Seismic Fragilities of Nuclear Power Plant Components
Seismic fragility is represented by a curve of the conditiional probability of failure as a function of the peak ground acceleration. Since there are many uncertainties in the model and...
Reliability Analysis in the Presence of Random Functions and Categorical Variables
This paper describes a reliability procedure that can handle certain classes of random functions and qualitative categorical variables. The method is an extension of the R. Rackwitz-B....
Expert Systems for Drought Management: A Case Study
This paper describes the development and application of a computer model used by the Seattle Water Department (SWD) for operations during drought. This model provides guidance for initiating...
Irrigation-Induced Contamination Problems
At the Kesterson National Wildlife Refuge in the San Joaquin Valley of California, severe fish and wildlife problems (waterfowl mortality, embryonic deformities, and reproductive failures)...
Tidewater Virginia's Water Supply Problem: Implications for State Water Management
Attempts to expand water supply in response to continuing urban growth in Virginia's Tidewater region has produced prolonged conflict among the area's local governments...
An Operations Advisor for Regional Water Management
The application of artificial intelligence techniques was evaluated for implementation for water control structure operations at the South Florida Water Management District. After an analysis...
Design of the Oasis Advisory System
Once the decision was made to develop an advisory system for the operation of water control structures within the South Florida Water Management District, a schedule of activities leading...
Modeling Hydrologic Components of the Upper St. Johns River Project
Off-line stormwater management areas and riverine marsh conservation areas are the major components of the Upper St. Johns River Project, Florida. Dimensions and operations of these components...
Sanitary Sewer System Modeling for Operation and Planning
Development of a Steady State Sanitary Sewer Simulation (S5) computer model helped Newport News, Virginia, enact an efficient sanitary sewer management...
Computer-Aided Wastewater Master Planning
Computerized wastewater collection system modeling is a tool now used by city planners and engineers to efficiently and accurately analyze present and future conditions. Once a model has...
Mass Transport Modeling of Pearl Harbor
The U.S. Navy is planning to implement the use of organotin antifouling paints into the fleet. Such paints are already in use by commercial vessels and private pleasure crafts. As part...
Reservoir Safe Yield Evaluation Using Simulation
The safe yield available from surface water impoundments serving the City of Portsmouth, Virginia, was evaluated, and the sensitivity of the reservoir system to several factors was investigated....
Determining Impacts of Sediment Using Cesium-137
Tecumseh Lake, in east-central Oklahoma, completed about 1934, has been identified by the Oklahoma Water Resource Board as a water supply critical to future development of the state. Aerial...
Conjunctive Use Study of Groundwater and Surface Water in Chino Basin, California
The purpose of this paper is to study the effects of artificial recharge on an already contaminated unconfined aquifer and propose optimal recharging and pumping schemes to prevent the...
