Dynamic Optimal Ground Water Remediation by Granular Activated Carbon
(American Society of Civil Engineers, 1998)Objective functions to describe the operating and capital costs of granular activated carbon (GAC) treatment are incorporated into a management model for dynamic optimal pump-and-treat groundwater remediation design. The ... -
State-Space versus Multiple Regression for Forecasting Urban Water Demand
(American Society of Civil Engineers, 1998)State-space and multiple regression methods were compared with each other and with simple monthly averages for the accuracy of their short-term forecasts of urban water demand. Seven sets of 24 monthly forecasts of water ... -
Utilizing Sparsity in Time-Varying Optimal Control of Aquifer Cleanup
(American Society of Civil Engineers, 1998)A method for exploiting the sparsity structure of a finite-element simulation model in a linked dynamic optimal control model is developed. The linked optimization/simulation model has been used for the computation of ... -
Presence of Nonconvexity in Groundwater Concentration Response Functions
(American Society of Civil Engineers, 1998)This study examines the presence of nonconvexity and multiple extrema in the feasible region defined by the concentration response function. The response function is defined in the context of concentration constraints ... -
Reservoir Operation Studies of Sabarmati System, India
(American Society of Civil Engineers, 1998)In India, reservoirs are usually constructed to serve multiple purposes, such as irrigation, municipal and industrial water supply, hydropower generation, and flood control. Because of the high temporal and geographical ... -
Computational Issues for Optimal In-Situ Bioremediation Design
(American Society of Civil Engineers, 1998)We have developed the first application of optimization techniques to the design of in-situ bioremediation, and have encountered a number of computational issues that have not arisen in previous efforts to optimize the ... -
Location and Schedule Optimization of Soil Vapor Extraction System Design
(American Society of Civil Engineers, 1998)Soil vapor extraction is a cost-effective technique for removing volatile organic compounds (VOCs) immobilized in the unsaturated zone. The design of a soil vapor extraction system (SVES) requires that the number and ... -
Decision Support System for Conjunctive Stream-Aquifer Management
(American Society of Civil Engineers, 1998)A decision support system (DSS) is presented for conjunctive management of surface water and ground water under prior appropriation. The DSS is constructed around the generalized river basin network flow model MODSIM, ... -
Assessing Lake Okeechobee Eutrophication with Water-Quality Models
(American Society of Civil Engineers, 1998)The South Florida Water Management District has developed a comprehensive management strategy to assess eutrophication in Lake Okeechobee. Key components of this strategy are research, monitoring, and modeling of the lake. ... -
International Duties and Obligations for Transboundary Water Sharing
(American Society of Civil Engineers, 1997)The need for effective water sharing agreements between sovereign states is increasing as more people and industries compete for use of that finite resource. To prevent conflict the affected parties must enter into an ... -
Water Availability in Mexico Considering Quantity, Quality, and Uses
(American Society of Civil Engineers, 1998)In water supply planning, managers must assess both quantity and quality of sources. These assessments require adequate data, which is not always available, even in developed countries, and much less so in developing ... -
Bootstrap Position Analysis for Forecasting Low Flow Frequency
(American Society of Civil Engineers, 1997)A method of random resampling of residuals from stochastic models is used to generate a large number of 12-month-long traces of natural monthly runoff to be used in a position analysis model for a water-supply storage and ... -
Value of Seasonal Flow Forecasts in Bayesian Stochastic Programming
(American Society of Civil Engineers, 1997)This paper presents a Bayesian Stochastic Dynamic Programming (BSDP) model to investigate the value of seasonal flow forecasts in hydropower generation. The proposed BSDP framework generates monthly operating policies for ... -
Comparison of Methods for Yield Assessment of Multiple Reservoir Systems
(American Society of Civil Engineers, 1997)This paper compares four different methods for estimating the yield of a multiple reservoir system. These include simulation, a combined simulation-optimization model (WATHNET), a full optimization model, and a simplified ... -

Multiobjective Watershed-Level Planning of Storm Water Detention Systems
(American Society of Civil Engineers, 1997)Detention basins are the most popular structural measure for urban flood control and have proven effective for both water quantity and quality management. Integrated, watershed-level planning of the layout and sizing of ... -
Estimating Non-Point-Source Loads and Associated Water Quality Impacts
(American Society of Civil Engineers, 1997)A water quality modeling project was undertaken to estimate non-point-source loading and associated water quality impacts for the Carson River in Nevada. As part of the modeling initiative, the WASP5 program was modified ... -
Central Flow Control in Sewer Networks
(American Society of Civil Engineers, 1997)Control methods are applied to sewer network flow in the aim of reducing pollution of receiving waters. A multilayer control structure consisting of an adaptation, an optimization, and a direct control layer may be used ... -
Riverbank Stabilization Program
(American Society of Civil Engineers, 1997)Erosion of riverbank property is a frequent occurrence along the dynamic river systems within Snohomish County. In the mid-1980s the County established a legal mechanism that allowed the county to cost-share bank stabilization ... -
