Structure of Coastal Upwelling on a Sloping Bottom
A large eddy simulation of coastal upwelling on a sloping bottom is carried out. The structure of the upwelling consists of a persistent primary front, a temporary secondary front which...
The Courant Number and Unsteady Flow Computation
The Courant number C, the key to unsteady flow computation, is a ratio of physical wave velocity, ?, to computational signal-transmission velocity, ?, i.e., C = ?/?. In this way, it uniquely...
Evaluation of Historical Scour at Selected Stream Crossings in Indiana
Geophysical data were collected by means of ground-penetrating radar and tuned transducer systems to estimate the historical scour at ten bridges in Indiana. These geophysical data were...
Variability in Solutions of Constrained Optimization Problems: Ocean Outfall Design Case
Uncertainty in optimization model resulting from parameter uncertainty has not been well studied in the hydraulics and water resources areas. To make valid decisions, knowledge of the...
Three-Dimensional Modeling of the Coastal Region Offshore from Sydney, Australia
Care must be taken in model formulation to ensure that unwanted internal circulation cannot be induced. Extensive model testing must be carried out on possible distorted element shapes...
Storm Water Regulations?Aircraft Deicer/Anti-icers Operations
In 1991, FAA has initiated a storm water program to assist airport operators in complying the EPA Storm Water NPDES regulations. The first FAA project, a survey, addresses present operational...
Sacramento River Environmental Requirements
Environmental requirements have altered bank protection engineering and construction on the Sacramento River, California. Conflicts between public safety and environmental protection remain...
Composite Construction?Recent Past, Present and Near Future
The present paper covers a shorter time span. It is divided into three parts: recent past, present and near future. The remarks regarding the recent past are limited to my personal experiences....
New Developments in Eurocode 4
The European Community has initiated the preparation of a set of harmonized structural codes. Eurocode 4 is the code for the design of composite steel and concrete structures. The first...
New Canadian Provisions Related to the Design of Composite Beams
In this paper, the new provisions in CAN/CSA-S16.1-M89 for the design of composite beams, together with reasons for changes, are discussed. Some of the new provisions reflect results of...
New Road Safety Initiatives in New Zealand
A considerable number of initiatives have been taken in New Zealand recently to keep pressure on the downward trend in road crashes and casualties. These have included government legislation...
Road Safety Audit: Prevention is Better Than Cure
Over the past two decades, the emphasis in road safety engineering has been on crash reduction through the development of remedial measures at high frequency sites. Road and traffic authorities...
Potential of Vegetable Oil as a Transportation Fuel
The esters of vegetable oils (Biodiesel) have potential as direct replacements for diesel fuel in compression ignition engines. This paper discusses fuel properties, short and long term...
Seeing the Future: Changing Highway Engineering Practice Over the Next 10 Years
The computer age is here, and the more a highway engineer knows about computers, the better. This really symbolizes the direction highway engineers are headed - into a high-tech world...
Influence of Lateral Wind on Driving on Offshore Bridge
The Honshu-Shikoku Bridges are a system of highways crossing over the sea, where cross-winds variously affect vehicle behaviour. This is the intermediate report on the surveys aimed at...
The Pontis Bridge Management System
A committee of the Federal Highway Administration and six of the United States has completed a network-level bridge management system, called Pontis, to optimize budgets and programs for...
Issues in GIS-Based Subsurface Data Management
Obstacles and barriers preclude an interagency GIS application for managing spatially-related subsurface data. Such a system would enable geotechnical and earthquake engineers from state...
National Geotechnical Experimentation Sites?Central Data Repository
A central data repository is in the process of development for the recently-established system of U.S. geotechnical experimentation sites. Data which will be available for most of these...
The Application of 3 Dimensional Geographic Information Systems in Geotechnical Earthquake Engineering
The requirements and needs of Geographical Information Systems (GIS) in geotechnical earthquake engineering are described, and the use of such system in New Zealand is discussed. We have...
Some Considerations for the Use of Geographic Information Systems
GIS have become widely used. Geotechnical earthquake engineers need both to understand what distinguishes a GIS form other data base systems and to make clear the purpose, use, and maintenance...
