A Second-Generation Wave Model for Coastal Wave Prediction
A second-generation numerical wave model, WINDWAVE, has been developed for wave prediction in coastal regions. The modal is based on the numerical integration of the energy balance equation...
Numerical Modeling of Waves in Harbors
The numerical wave model HARBD has been used extensively for estimating waves in harbors. The model is used to simulate laboratory tests of long waves in a rectangular harbor with variable...
Evolutionary Fourier Analysis of Wave Data
A new method is presented for analyzing nonstationary water level height time series. The usual assumption of pseudo-stationary intervals is avoided and the wave spectra can be changing...
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...
Modeling Bottom Friction in Wind-Wave Models
Effects of bottom friction in wind-wave models are investigated, with an emphasis on wave-induced bottom roughnesses (moveable-bed effects). A state-of-the-art bottom friction model is...
Kinematics of Wave Overtopping on Marine Structure
Kinematics of transient wave overtopping on coastal breakwaters has been studied both experimentally and numerically. For the laboratory experiments, solitary waves with moderate wave...
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...
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...
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...
Operational Interactive Hydrologic Forecasting with the National Weather Service River Forecast System
The National Weather Service River Forecast System (NWSRFS) consists of several major hydrometeorologic subcomponents to model the physics of the flow of water through the hydrologic cycle....
Problems Faced by Faculty in Minority Institutions
The primary objective of this paper is to list some problems faced by faculty engaged in both research and instruction in Minority Institutions (MIs) and to suggest solutions to them....
Optimization of the Design and Operation of Soil Vapor Extraction Systems
Volatile organic compounds (VOC's) immobilized within the soil unsaturated zone constitute a significant source of groundwater contamination. Soil vapor extraction systems (SVES's), which...
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...
Probabilistic Characterization of Droughts
The Palmer Drought Severity Index (PDSI) uses a set of meteorologic and hydrologic variables to create a numerical value for drought severity. The index values are grouped into drought...
Application of the PCRSS Reservoir Simulation Model to the Salt River Project
PCRSS is a general purpose reservoir system model construction kit. It allows the user to specify the system configuration and parameters through the use of a windows based graphic user...
A Decision Support System for Multi-Purpose Reservoir Operations
A generalized decision support system (DSS) is presented for developing optimal operation policies for multi-purpose reservoirs. The model is designed for single reservoirs, although is...
Design Considerations for Night Storage in Irrigation Systems
Due to the farmer social and economical changes, irrigation during night became rare. Most of the night discharges flow to drains. A design procedure has been developed for storage in...
Modeling Flow in Variably-Saturated Porous Media
An expression for effective hydraulic conductivity to solve groundwater flow problems is developed. Also, a refined Monte Carlo (MC) simulation procedure is proposed. The developed methodologies...
Multiobjective Models for Determining Freshwater Inflows to Bays and Estuaries
