Aquifer Storage and Recovery at the Centennial Water and Sanitation District
water in a suitable aquifer, the peak time capacity of CWSD could be increased while delaying the water treatment plant (WTP) expansion currently scheduled for 1996. To validate this assumption,...

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...

Channel Stabilization and Retrofit
In 1990 King County Surface Water Management Division completed the Soos Creek Basin Plan. This basin was one of the most rapidly developing areas in the State of Washington. The goal...

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...

Surface Water Quality Modeling in the Rio Grande
The City of Albuquerque (City) in New Mexico owns and operates the Southside Water Reclamation Plant (SWRP), which discharges an average of 200623 m3/d...

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...

How Many Observation Wells Does it Take to Find a Groundwater Contamination Plume?
A Bayesian data worth framework is developed to balance the benefits and costs of data collection. In addition to Bayesian decision analysis, tools from Monte Carlo simulation, numerical...

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...
