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...
Wave Transformation and Load Reduction Using a Small Tandem Reef Breakwater ? Physical Model Tests
The performance of several small reef breakwaters, and a tandem breakwater system (consisting of a reef breakwater positioned upwave from a surface-piercing main breakwater), are quantified...
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...
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...
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...
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...
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...
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...
Plate and Frame Membrane Air Stripping
This paper examines utilization of a plate and frame membrane air stripping system for the removal of volatile organic chemicals (VOCs) and radon from a water supply. Previous work explored...
An Interactive Regional Regression Approach to Estimating Flood Quantiles
In Texas, a computer program has been developed which will estimate flood quantiles for an ungaged site based on data from gaging stations with similar watershed characteristics. The user...
