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...

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...

Explicit Stochastic Modelling of a Reservoir for Hydropower Production
A new reliability model for planning the operation of a multipurpose reservoir for hydropower generation and flood control, which considers the stochastic nature of inflows and power demand...

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...

Optimal Operation of Soil Aquifer Treatment System
Mathematical models based on nonlinear programming are developed for operating soil aquifer treatment(SAT) systems. The objective of these optimization models is to determine the operation...

Water Resource Modeling and Consensus Building
The steps undertaken to develop consensus with respect to analyzing a complex and competitive water resources/water rights situation through the development of a simulation model are described....

Addressing Central Valley Project Policy Issues Using a General-Purpose Model
The U.S. Bureau of Reclamation's Central Valley Project (CVP) in California is constantly undergoing changes in legal mandates and policy objectives. Due to the complex nature of existing...

Joint Optimization of Groundwater Remediation and Monitoring
We describe the challenge of devising optimization methods which optimize jointly the remediation and monitoring at a contaminated site. We refer to the dual control method as a promising...

Simulating Hourly Hydropower Operations for the Assessment of Environmental and Economic Impact
Generation of peaking power at Glen Canyon Dam causes river flow and stage to fluctuate on an hourly basis. This has been shown to impact the downstream physical and biological environment....

Integration of Water Rights and Network Flow Modeling in the Upper Snake River Basin
The U.S. Bureau of Reclamation's Pacific Northwest Region and Denver Office are working to enhance the ability to integrate hydrological and institutional modeling capabilities for use...

PROSIM - A Water Rights-Based Operational Simulation Model of the Provo River
The development and initial application of a computer model of the hydrology, water rights, and operation of the Provo and Weber rivers in Utah are described. The new FORTRAN model PROSIM...

Predicting Hydrologic Impacts of a Severe and Sustained Drought on the Colorado River Basin
We investigated the impacts of a severe and sustained drought (SSD) on the hydrology of the Colorado River Basin. The simulation was carried out using the Colorado River Network (CORN)...

Economic Impacts of Severe and Sustained Drought
A hydrologic-economic-legal impact model shows that a severe and sustained drought in the Colorado River Basin would cause acute economic damages to most instream water users, and to upper...

Missouri River Economic Impacts Model
The Missouri River basin recently (1987-1992) experienced a drought that affected project uses and environmental resources. This drought and the need to address changes that have occurred...

Stochastic Optimal Control for Determination of Freshwater Inflows to Estuaries
The objective of the research is to develop estuarine system management models based upon discrete-time stochastic optimal control. An analytical feedback control law is given. The control...

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...

Development and Application of Long Range Study (LRS) Model for Missouri River System
The Long Range Study (LRS) Model is a simulation model developed in the 1960's develop and test criteria for operation of the Missouri River mainstem reservoirs through an extended period...

Computer Simulation Model of the Integrated Local Water Supply Plan for the City of Wichita, Kansas
The City of Wichita, Kansas will require additional water supply sources to meet projected future water demands. A study of options identified a supply plan with integrated use of local...

Development of a Wetland/Riparian Resource Model for the Missouri River System
Wetlands and riparian areas are significant resources along the Missouri River, providing important fish and wildlife habitat. These resources required evaluation as part of the review...

Missouri River Least Tern and Piping Plover Model Development
As part of the update of the Missouri River Master Water Control Manual, the U.S. Army Corps of Engineers is evaluating the effects of numerous water management alternatives on endangered...
