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...

Optimal Supply of Parking at Airports
The design capacity of parking facilities at airports is generally estimated in relation to one or more standard decision variable such as enplaning passengers, number of employees, and...

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...

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....

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...

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...

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...

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...

Sustainable Management of Existing Reservoirs
Instead of a design and planning of new reservoirs in the future, more emphasis will be placed on the management of existing reservoirs. Reservoir storage reallocation and reassessment...

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: 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...
