The Importance of Density Driven Circulation in Well Mixed Estuaries: The Tampa Bay Experience
This paper addresses the importance of the effects of baroclinicity in subtidal dynamics of a well mixed estuary, Tampa Bay. The analysis is based upon numerical simulations using a three-dimensional,...
Application of a Boundary Fitted Coordinate Mass Transport Model
A three-dimensional, boundary fitted coordinate, finite difference, mass transport model was applied to the Providence River in Upper Narragansett Bay, Rhode Island. The governing advection-diffusion...
Assessing
The New York Bight had been receiving waste disposals, dredged spoils and acid dumps for the past 30-40 years causing accumulation of trace metals such as Cu(II) in water and sediment....
A Semi-Implicit Finite Difference Model for Three-Dimensional Tidal Circulation
A semi-implicit finite difference formulation for the numerical solution of three-dimensional tidal circulation is presented. The governing equations are the three-dimensional Reynolds...
Modelling of Coastal Circulation in Singapore Waters?A Hybrid Approach
A hybrid modelling technique which involves the integration of numerical and physical models has been used to study tide induced circulation in Singapore coastal waters. The modelling...
A Modified Adjoint Method for Inverse Eddy Viscosity Estimation for Use in Coastal Circulation Models
The adjoint method is used to develop an objective analysis technique for estimating the vertical eddy viscosity used in three dimensional oceanic models. A cost functional which consists...
Evaluating Spillway Adequacy
More than a third of all dam failures are caused by overtopping. Equipment malfunctions or operations errors are sometimes to blame, but the principal cause is inadequate spillway capacity....
New Hong Kong International Airport
The airport at Kai Tak has served as a viable commercial operation since the lat 1930s and has played a pivotal role in the territory's development. The fact that Kai Tak has a finite...
Customer Requirements in Industrialized Housing
Residential construction efforts in the U.S. are highly fragmented, and this has slowed the application of new technologies. While there has been an increase in the use of manufactured...
Evaluating the Effectiveness of Transportation Control Measures for San Luis Obispo County, California
The San Luis Obispo Air Pollution Control District has developed simple techniques to estimate emission reductions from various Transportation Control Measures. Accurate emission estimates...
Laboratory Tests of Modal Emissions and Off-Cycle Corrections to FTP-75
The modeling of emissions from on-road mobile sources is an on-going process. Two broad topics which are currently under study are the evaluation of driving cycles and the development...
Developing Protocols for Motor Vehicle Air Quality Modeling
This paper is directed to air quality analysts. It examines the issues surrounding a modeling protocol and how to work effectively with a traffic engineer on a project to model carbon...
The General Theory of Quantitative Risk Assessment
From the many individual applications of quantitative risk assessment (QRA) that have been made in various fields, this paper abstracts and lifts out the concise, simple, and elegant cluster...
Aversion to Epistemic Uncertainties in Rational Decision Making: Effects on Engineering Risk Management
When faced with epistemic uncertainties in a decision problem, subjective expected-utility theory (SEU) implies that the only relevant characteristic of these uncertainties is the mean...
On Deciding Between the Use of Engineering Standards and Risk Analysis
Risk analysis offers advantages for the optimal design and maintenance of infrastructure, but it is not always practical to apply due to the nature of certain types of infrastructure....
System Engineering and Risk
System engineering means many things to many people, but there is a large group of practicing engineers in the defense and energy sectors who define system engineering as a structured...
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....
Reliability Analysis of Lunar Structures Under Meteoroid Impact
The United States is slowly moving towards lunar base, and possibly Mars base, activities. Design of structures for these bases requires knowledge about loadings and conditions which in...
Response Variability and Reliability of Plates Using the Weighted Integral Method
A methodology is introduced to perform both the response variability and reliability analysis of two-dimensional stochastic systems (specifically plates subjected to plane stress or plane...
