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...

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
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...

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 Reassessing the Operation of the Chungju Reservoir System
The Chungju Reservoir is a component of the Han River System in Korea. Chungju Reservoir consists of a main reservoir and a downstream smaller reservoir that serves as an after bay. It...

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...

Building Groundwater Optimizers That Respond to the Needs of Decision-Makers
Optimization methods are being sought and employed to design systems that remediate contaminated groundwater regions (and, in fact, the subsurface in general) with increasing frequency....

Uncertainty in Reservoir Operation Optimisation
The water resources literature is rich with the application of optimisation techniques in the presence of uncertainty. This paper presents a brief overview of the various ways uncertainty...

Integration of Water Quantity and Quality Planning
This paper describes the integration of water quantity and quality objectives within the framework of a computerized interface design to assist with the difficult process of long-range...

Description of the Application of Goal Programming for Selective Withdrawal Structure Operation
Thermal stratification in reservoirs results in variations of water quality with depth. Selective withdrawal structures with outlets at different vertical locations, can be used to provide...
