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...

Recycling Portland Cement Concrete Pavement at the Contractor's Option
This paper summarizes three portland cement concrete airfield pavement recycling projects at the Outagamie County Airport in Appleton, Wisconsin. The specifications for the projects did...

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...

Development of Hydro-Scheduling Model for Optimal Joint Operation of Multi-Reservoir Systems
Multipurpose reservoirs in a reservoir system are not limited to supplying ample amounts of water and electricity, but also provide other water demands such as flood control, navigation,...

Optimization and Reservoir Operations for the Missouri River
As demands placed on the operation of the nation's reservoirs increase, the problem of finding the most desirable set of operation plans becomes more difficult and controversial. This...

Parameter Regionalization of a Daily Baseflow Runoff Model
Daily baseflow values are required to characterize the environmental measurements being carried out in several basins in the Province of Genova, northern Italy. The main purpose of these...

Wind Lake Improvement Plan Dredging Project Wind Lake, Wisconsin
Dredging has been used historically to improve navigation, however, it usefulness as a water quality improvement tool has not been widely proclaimed. Although costly to undertake, dredging...

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...

Geographically Distributed Decision Support; The Tennessee Valley Authority (TVA) TERRA System
The Tennessee Valley Authority (TVA) has a long history of managing the water provided by the Tennessee River and its tributaries. TVA is responsible for such diverse water interests as...

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...

Recreating a Process: The West Georgia Regional Water Supply Plan
This paper describes the planning process used to develop a long-range water supply plan for a five-county area northwest of Atlanta, Georgia. Demand for water in the study area is projected...

Missouri River Recreation Economic Analysis
The Missouri River main stem lakes and downstream river reaches encompass about 1900 river miles from the mouth at St. Louis, Missouri, to the headwaters of Fort Peck Lake in Montana....

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...
