Sediment Intrusion into the Substrate of Gravel Bed Streams
A physically-based model was developed to simulate the intrusion of fine sediments into stream gravel substrates and its effects on intragravel flow. The model is capable of simulating...
Ecological Impacts of Sediment Transport to Tropical Reservoirs
Sediment transport and siltation influence both the longevity and ecology of tropical reservoirs. The sediment load to these systems is typically seasonal and affects ecological processes...
Sedimentation at Canal In-Line Structures
This paper describes the procedures used to compute the transport capabilities of existing canals and the process for predicting sediment deposition that will occur at or near the modified...
Modeling Erosion and Sedimentation in Irrigation
Sediment yield and erosion modeling approaches for sprinkler and surface irrigation are discussed. Empirical approaches, such as the ULSE, and other regression approaches and their applicability...
Reliability Constraint on Optimum Design
The purpose of the paper is to emphasize the importance of the probability concern on optimum design work. The probability of failure of the structure can be considered as one of the optimum...
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...
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...
Some Perspectives and Philosophies on Risk-Based Decision Making in Water Resources
The authors have selected four perspectives of the water resources decision problem that illustrate how formal risk-based approaches may be applied - an economic perspective, an environmental...
Environmental Considerations in Risk-Based Decision Making in Water Resources
In the hypothetical Royal River Project there are several factors pertaining to environmental issies; these factors have a bearing on selection among the several alternatives and lead,...
Transportation Infrastructure Information Systems
The current crisis in the nation's transportation infrastructure necessitates the development of innovative data management systems to facilitate and implement analysis algorithms...
The Metropolitan Boston Area Earthquake Loss Study
This study develops an inventory of critical facilities in the Metropolitan Boston area and analyzes the impact of a project earthquake (Cape Ann Event) on their structural integrity and...
Lifeline Risk Analyses: The Mokelumne Aqueduct Study
Probabilistic risk analysis methods are applied to the evaluation of seismic and non-seismic vulnerability of a 25-kilometer length of a major lifeline aqueduct system. In addition to...
Design of Impact Limiters for Waste Fuel Shipping Casks
Impact limiters are often used to control the decelerations experienced by a waste fuel shipping cask when it is subjected to the hypothetical accident condition loadings. Simplified design...
A Cost Effective Quality Control Program for Commercial Construction
The construction industry recognizes the important need for a formalized quality control program to assure the safety of our structures. The successful program is one in which the owner,...
Statistical Analysis of Tellico Dam Piezometer Data
The purpose of this paper is to demonstrate the use of statistical and computer processing methods as a tool for analyzing dam safety piezometric monitoring data. Statistical methods are...
Coordination of Interconnected Arterial Traffic Signals
Present analytical methods and computer programs offer capabilities of optimizing the traffic signal coordination for a series of signalized intersections. Recently, transportation research...
Endangerment Assessment in a Multilayered Aquifer Using a Microcomputer Based Transport Model
An endangerment assessment describes the types and degrees of potential hazards to public health, welfare, or the environment that may result from the release of hazardous substances into...
Expert System for Risk Assessment of Concrete Dams
An expert system is presented that will assist a field inspector, during the site investigation of an existing concrete dam, to perform a preliminary structural risk assessment of the...
Westway - The Little Word that Killed the Big Highway
The Westside Highway Project, better known as Westway, received a construction permit on February 25, 1985 from the Army Corps of Engineers. Signed by the author, the permit was invalidated...
