The Evolution of Breakwater Design
The purpose of this paper is to present a view of the evolution of both the rubble mound and vertical faced breakwaters from the earliest design through the Iribarren and Hudson era. Determining...

Airport Terminal Design Challenges
In February 1989, the Metropolitan Washington Airports Authority began the process of designing and constructing a new terminal at Washington National Airport to address the needs of its...

Dynamic Loading of Airfield Pavements Caused by Aircraft Operations on Rough Runways
This paper presents results for dynamic pavement loading of various aircraft under takeoff and taxing scenarios. The data were obtained from computer simulation and applied to the Corps...

Implementation of Elastic Layered Theory for Design of Unbonded Overlays
The U.S. Army and Air Force have implemented the elastic layered theory for design of unbonded overlays for rigid airfield pavements. The procedure allows for design of unbonded overlays...

Utilization of Phosphogypsum-Based Slag Aggregate in Portland Cement and Asphaltic Concrete Mixtures
This study centers around the potential utilization of phosphogypsum-based slag aggregate as a substitute for coarse aggregate in both portland cement and asphaltic concrete surfaces for...

Nighttime Cement Concrete Pavement Replacement Seattle-Tacoma International Airport
Several airfield improvement projects are currently underway at Seattle-Tacoma International Airport (Sea-Tac), many of which are being constructed using cement concrete pavement. Due...

Rail-Air: A Multi-Modal Opportunity in a Changing World
The purpose of this Paper is to examine the applicability of rail links to major airports and the benefits they can bring. It will seek to identify the key success factors and the extent...

Joint Probability Distribution of Rainfall Intensity and Duration
Intensity-duration-frequency (IDF) curves are widely used for peak discharge estimation in designing hydraulic structures. Accurate interpolated and extrapolated intensity values are difficult...

Integration of Reliability, Uncertainty and Optimization in Hydraulics Systems: Classification of Problem Types
Design and operation of hydraulic systems can be an extremely complex task. Although not widely accepted the application of deterministic optimization techniques can provide guidance to...

Integration of Reliability, Uncertainty and Optimization in Hydraulics Systems: Structural Reliability
The focus of this paper is to provide an overview of analysis and optimal design of systems in which the system reliability is dependent upon the structure of the system (such as the layout...

Designing Optimal Reliable Multiquality Water Supply Systems
A methodology which integrates optimal design and reliability of a multiquality water supply system is presented and demonstrated. The system constructed is able to sustain prescribed...

Integration of Water Quantity and Quality Planning
This paper describes the integration of water quantity and quality objectives within the framework of a computerized interface design to assist with the difficult process of long-range...

Considering Uncertainties in Water Resource Designs
Design of water resource systems often faces with various uncertainties. The nature of problems in essence are decision making under uncertainties. This paper offers an introduction to...

Tug Fork Flood Plain Modifications and Wetlands Mitigation
The West Virginia Department of Highways (WVDOH) is using a two stage channel excavation concept to mitigate the hydraulic impacts of relocating U.S. Route 119. The selected highway alignment...

Managing the Russian River Aggregate Resources
As a result of analyzing the Russian River and its capacity to provide gravel, and through a sound examination of the geomorphology, hydrology, and groundwater conditions, the Sonoma County...

Concrete Watertight Structures and Hazardous Liquid Containment
The purpose of Concrete Watertight Structures and Hazardous Liquid Containment is to provide a practical guide for practicing engineers who...

CAD for Small Hydro Projects
The quest to reduce design costs and improve design quality by raising productivity is familiar to every manager and designer. This article examines how CAD can play a role by examining...

Success Syndrome: The Collapse of the Dee Bridge
Scaling up existing successful designs can cause latent weaknesses to become dominant, leading to catastrophe. By studying past failures where this has happened--for example, the 1847...

MPOS Become VIPS
The 1991 Intermodal Surface Transportation Efficiency Act made metropolitan planning organizations very important players in transportation decisionmaking. MPOs have been around since...
