A New Correction Procedure for Shipborne Wave Recorder Data
A new correction procedure for Shipborne Wave Recorder (SBWR) wave height and spectral data is described. The method is based on a reassessment of the available frequency response measurements...
Extensive Comparison of Directional Wave Analysis Methods From Gauge Array Data
In order to settle an efficient operational wave gauge array for estimating directional wave spectrum, several directional analysis methods are implemented and compared. These methods...
Case Studies of Extreme Wave Analysis: A Comparative Analysis
Several methods of extremal wave analysis have been applied to two sets of deep water extreme wave data. One set consisted of three-hourly sea-state records collected during a nine year...
Getting the Project Started
In 1987, the newly formed Washington Metropolitan Airports Authority began a long term Capital Development Program which will change how both Washington National and Dulles International...
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...
Airports and Air Quality Issues - the European Perspective
This paper presents a detailed review of air quality studies at European Airports since 1986. It also provides a brief analysis of the air quality section of a recent ACI (Europe) environmental...
Reservoir Operation Using Bayesian Inferencing and Balancing Rules
The water resources problem addressed in this paper is real-time, multi-purpose reservoir operation. Specifically, daily, or at the most, weekly operations are considered. A hybrid modeling...
Evaluating Sensitivity of Hydraulic Control Optimization Models
Sensitivity of hydraulic control optimization models to variation in gradient constraints is examined. Monte Carlo simulation is used in conjunction with repeated optimization runs to...
Water 2050-Supply for the Portland, Oregon Metropolitan Region Using the Integrated Resource Planning Process
This paper presents information about the long range regional water supply planning work that is being conducted in the Portland, Oregon metropolitan region. An integrated resources planning...
Thoughts of Reservoir Management Studies
Changing water use patterns and priorities, the high cost and uncertainty of developing new supply sources, increasingly stringent environmental regulation, and the desire and need to...
Aquifer Remediation Design: Nonlinear Programming and Genetic Algorithms
Nonlinear programming and genetic algorithm solutions of a pump-and-treat aquifer remediation design model are presented and discussed. These models find the minimum cost design of the...
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...
A Physically Based Conceptual Model for Simulating Contaminant Levels in Subsurface Water
A conceptual physical model is developed to simulate solute transport and mixing in the vadose (unsaturated) and groundwater zones. The conceptual model couples lumped-parameters models...
The Everett, Washington, Water Supply IRP
The City of Everett, Washington, supplies water to most of the population of Snohomish County, located just north of Seattle. The County is rapidly urbanizing, and preliminary review of...
Partnering in Environmental Restoration: The Coastal America Model
The Coastal America Partnership was initiated in 1993 with the underlying principal that collaborative efforts would be more successful than attempting individual agency solutions. To...
Climate Change Impacts on Boston's Water Supply
The analysis of the climate sensitivity of the water supply system of the Boston area indicates that the water supply has the potential to be dramatically altered by global warming. The...
Wetland Loss Rates and Agricultural Drainage
The current paper uses National Resources Inventory data to document the relation between private on-farm agricultural drainage investment activity and wetlands loss. The paper presents...
Peak Runoff Prediction for Small Rural Watersheds
A regression model for peak runoff prediction from small rural watersheds was developed using the rainfall/runoff data collected from 43 watersheds in the front range of the State of Colorado....
Multiobjective Models for Determining Freshwater Inflows to Bays and Estuaries
This paper presents four multiobjective models for the estuary management problem, including goal programming, the epsilon constraint method, the surrogate worth tradeoff method and the...
