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...

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...

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...

Differential Dynamic Programming for Estuarine Management
Differential dynamic programming (DDP) is applied to solve the estuarine management problem to determine the optimal amount of freshwater inflows into bays and estuaries in order to maximize...

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...

An Interactive Regional Regression Approach to Estimating Flood Quantiles
In Texas, a computer program has been developed which will estimate flood quantiles for an ungaged site based on data from gaging stations with similar watershed characteristics. The user...

WATSUP: A Simulation Model for Water Supply Cost and Reliability
WATSUP (Water Supply) is a computer model developed to provide a prototype modeling tool for planners to estimate the costs and reliability of urban water supply systems on a regional...

Parallel SDP for Multi-Reservoir Management
The use of stochastic dynamic programming (SDP) for solving water resources problems has been restricted to problems with low dimension due to the 'curse of dimensionality'. Algorithm...

Evaluating the Steady State Stochastic Dynamic Programming Model for the High Aswan Dam
The paper describes the results of a study to critically evaluate and test the Steady State Stochastic Dynamic Programming model (SSDP). Whenever a reservoir computer model is developed,...

Wet Detention Facility Pollutant Removal Modeling
This paper documents development of the WETPOND model, which simulates long-term pollutant removal by a wet detention facility. Pollutant removal is determined with an EPA procedure that...

An Integrated Approach to the Real-Time Control of Water Supply and Distribution Systems
In recent years, real-time automated operation and control schemes have been implemented for a number of water supply and distribution systems with varying degrees of success. This paper...

CAD for Small Hydro Projects
The quest to reduce design costs and improve design quality by raising productivity is familiar to every manager and designer. This article examines how CAD can play a role by examining...

Graphical-Based Productivity Transient Investigation Using DISCO
Construction operations involve complex resource interactions and are typically performed in the field with exogenous factors such as inclement weather conditions and equipment breakdowns....

SCHEREC: SCHedule RECovery System
Creating a revised plan requires experience and significant time. To lessen the effort involved, a knowledge-based system named SCHEREC (SCHedule RECovery) was developed which suggests...

An Integrated Approach To Repetitive Construction Planning
Repetitive construction projects are unsuited for the use of the Critical Path Method (CPM) for their scheduling. Statistical simulation techniques offer a scheduling alternative, but...
