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...
Dynamic Maps for Seismic Risk Reduction and Effects of Soil Conditions
In order to perform useful vulnerability and risk evaluations, it is essential to have at one's disposal an automatic procedure of elaboration which provides answers in real time as soon...
Practical Implementation of Seismic Probabilistic Risk Assessment
Many techniques for seismic probabilistic risk assessment have been developed by university researchers over the last decade. This paper reports on a study being conducted to determine...
Bridge Repairs?Unexpected Effects on Reliability
There is a significant probability that a bridge will require repairs at some time during its service life. Repairs correcting one deficiency can cause other, unanticipated problems. Awareness...
Rehabilitation of Highway Bridges: Design and Operational Considerations
The design of a rehabilitation of a bridge which must maintain some lanes of traffic requires special consideration of construction procedures and traffic control, which are discussed...
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...
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...
A Simple Nonpoint Source Groundwater Quality Management Model
A model is examined which efficiently produces information required by decision makers to assess water quality tradeoffs associated with alternative groundwater protection strategies,...
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...
Regional Water Cooperation: An Alternative to Interbasin Transfer
Due to political and environmental impacts interbasin transfer is often regarded as an undesirable alternative for water supply development. However, water authorities will pursue interbasin...
Conflict Over Urban Water: An Economic Perspective
Water conflicts in the East are associated primarily with infrequent proposals by public water systems to move water across political boundaries. Also, most conflicts arise among political...
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...
Assessing WQ Impacts Using a Hydraulic Model
Engineering projects may cause water quality impacts in estuarine systems. It is important to assess those impacts during the planning phase of the project so that mitigation measures...
Sea Level Rise and Water Resources Management
Sea level rise due to greenhouse effect will create significant impacts on coastal water resources management. Possible future management strategies to offset salinity intrusion and to...
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 Model with Database Management
While numerous water supply and stormwater system models existed, the few sanitary sewer models that were readily available were too simplistic for engineering design and master planning...
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...
