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...
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...
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...
Lesson Learned form Implementing M&I Optimal Water Delivery
Few municipal water delivery systems are truly optimized to deliver a quantity of water at the least cost. Both the University of Kentucky and Memphis State University have attempted to...
Analysis of Missouri River System Operations Alternatives
The Corps of Engineers is conducting a study of alternative water control plans for the exiting Missouri River Mainstem System. Data on the effects of the alternatives on the various project...
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...
Opportunities, Constraints and Change in Reservoir Management
Changing hydrologic, economic, social and environmental conditions have focused attention on the opportunities for changing reservoir management. Such change can occur in three areas....
MPOS Become VIPS
The 1991 Intermodal Surface Transportation Efficiency Act made metropolitan planning organizations very important players in transportation decisionmaking. MPOs have been around since...
A New Automated System for Decision Support in the Construction Industry
This paper describes a collaborative project to research and develop a computer based decision support system for the construction industry. The system is intended primarily for use during...
CAD-Based Intelligent Drawings: An Automated Quality Control Approach to Land Development
Computer-Aided Design (CAD) is currently used within every discipline of civil engineering. Initially, CAD was employed solely as a drawing/drafting tool. Current CAD packages, in conjunction...
Applying Multimedia Technology to Project Control
Construction project control and documentation require an accurate, complete, and efficient way of collecting, storing, and retrieving project information. This information contains construction...
Use of Expert Systems in Selecting Equilibrium Isotherms of Organic Compound Adsorption on Activated Carbon
An outline of an Expert System (ES) that aids in selecting adsorption isotherms is presented. Such an ES provides an efficient technique for screening the present literature. The ES helps...
SCADA System Controls Combined Sewer Overflow Regulation System to Optimize Wastewater Collection
The Metropolitan St. Louis Sewer District's Overflow Regulation System (ORS) project uses computer control of a wastewater collection system for the purpose of combined sewage overflow...
A Computerized Methodology for Conducting Pedestrian Gap Studies
this paper will detail recent improvements with the procedure the New York City Department of Transportation utilizes when conducting Pedestrian Gap Studies. These improvements were made...
Water Infrastructure Risk Ranking and Filtering Method
The availability of water distribution infrastructure is critical to the sustained support and growth of society. Water infrastructure consists of systems that carry water (pipe and irrigation...
Flood Loss Assessment with Integrated Measures
In most cases, the maximum flood loss reduction can be achieved only by an optimal combination of both structural and nonstructural measures. An integrative approach that combines the...
Application of Numerical Models in the Design of Clarifiers
In this study, a numerical model of a circular clarifier was applied to reveal the effects of the water depth on the hydraulic and removal efficiency. The velocity and solids concentration...
Evaluating Activated Sludge Secondary Clarifier Performance: A Protocol
To establish a consistent methodology for evaluating secondary clarifier performance, the ASCE Clarifier Research Technical Committee prepared procedural guidelines in the form of a draft...
Sludge Hopper Design for Activated Sludge Clarifiers
Only in the past few years has any attention been allocated to the transport characteristics of sludge collectors. However, no attention has been given to a design rationale for the sludge...
Evaluation of Fe oxide-coated GAC for removal and recovery of Cu(II) from water
A composite solid, prepared by precipitating an Fe oxide onto granular activated carbon (GAC), was evaluated as an adsorbent for the removal and recovery of Cu(II) from water. Relative...
