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...

A Spectral Wave Model for the Coastal Zone
Spectral wave models that represent the evolution of the waves on a grid superior in several respects to conventional wave ray models. Spectral models on a grid have been developed for...

The Time Dependent Ray Method for Calculation of Wave Transformation on Water of Varying Depth and Current
This focuses on an aspect of the numerical calculation of wave refraction using the ray tracing or the semi-Lagrangian approach. the conventional ray method for steady state depth and...

Second Order Irregular?Wave Generation in Flumes - Computation of Transfer Functions by an Asymptotic Summation Method
Recently the theory for second order irregular-wave generation (including superharmonics as well as subharmonics) has been rederived for a variety of different types of wave board motion....

Evolution of Breaking Directional Spectral Waves in the Nearshore Zone
Methods used in parabolic refraction-diffraction models for computing the evolution of monochromatic waves in the nearshore zone are used to construct a model for spectral wave conditions....

Optical Remote Sensing of Wave Surface Kinematics
The measurement of the directional properties of surface slopes, velocities and accelerations is difficult, even in the laboratory, under conditions of steep, random and short-crested...

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...

Removal Of Chromium From Groundwater Using Permeable Barriers: An Aquifer Simulation Study
Previous efforts to remediate groundwater contaminated by chromium-bearing industrial wastes have involved post-extraction methods, whereby groundwater is pumped to the surface treated...

BPA Realtime Hydrologic Forecasting System for the Columbia River Basin
Bonneville Power Administration (BPA) markets and distributes the hydroelectric power produced at 30 federal projects in the Columbia River Basin. In order to plan the System's coordinated...

A Satellite Based River Forecast System for the Nile River
The initial version of the Nile Forecasting System developed by NOAA was used operational in July, 1993. Forecast System accuracy exceeded expectations. The Nile Forecast Center is now...

Optimization of Reservoir Releases to Control River Sedimentation Using Differential Dynamic Programming
A new methodology is developed to address sedimentation control in alluvial rivers downstream of reservoirs. An optimization model is posed as a discrete-time optimal control problem to...

Managing Reservoir Storage for Fish Production
Salmon populations in numerous Pacific Coast rivers are in decline and are in danger of becoming threatened or endangered. A reservoir system simulation model was developed for the Trinity...

Water Resources Education and Research at a Model HBCU Water Resources Center
Central State University has the nations only fullfledged degree program in water resources management at the undergraduate level. The program was founded on the assumption that water...

Elmhurst Quarry Flood Control Project
Conversion of a limestone quarry into an off-line reservoir provides flood protection for a rapidly developing County in the suburbs of Chicago....

Evaluating Multi-Purpose Reservoir Operations Using Fuzzy Dynamic Programming
The study described in this paper was designed to assess the feasibility of reservoir operators and water users defining membership functions for evaluating multiple objectives and to...

Using GIS to Develop 2-D Hydraulic Models
As communities along rivers and streams continue to develop, the demand for more accurate floodplain analysis and flood warning will also increase. Computer systems continue to develop...

Design and Implementation of an Optimal Real-Time Hydropower Generation Scheduling System for the Lower Colorado River in Texas
The Lower Colorado River Authority (LCRA) of Texas supplies water and electric power to over 800,000 persons in Central Texas. A real-time decision support system is being developed and...

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...

Aquifer Remediation Design: Nonlinear Programming and Genetic Algorithms
