Cost Considerations in Planning Pier Terminals
The deregulation of the air transport economy is gradually leading to the involvement of private developers in airport terminal financing. Even the airports run by government agencies...
Airports and Air Quality Issues - the European Perspective
This paper presents a detailed review of air quality studies at European Airports since 1986. It also provides a brief analysis of the air quality section of a recent ACI (Europe) environmental...
Operational Interactive Hydrologic Forecasting with the National Weather Service River Forecast System
The National Weather Service River Forecast System (NWSRFS) consists of several major hydrometeorologic subcomponents to model the physics of the flow of water through the hydrologic cycle....
Optimization of Reservoir Releases to Control River Sedimentation Using Differential Dynamic Programming
A new methodology is developed to address sedimentation control in alluvial rivers downstream of reservoirs. An optimization model is posed as a discrete-time optimal control problem to...
Development of Hydro-Scheduling Model for Optimal Joint Operation of Multi-Reservoir Systems
Multipurpose reservoirs in a reservoir system are not limited to supplying ample amounts of water and electricity, but also provide other water demands such as flood control, navigation,...
Dry Weather Stormwater Management - Yakima, WA
The city of Yakima recently completed a Comprehensive Stromwater Management plan to: 1) assess current and projected local runoff quality and 2) develop strategies to improve receiving...
Genetic Algorithms and Neural Networks: Do Pluralized Techniques Hold Any Advantages for Designing Groundwater Quality Assurance Systems?
Methods have recently been developed for designing groundwater monitoring and pollutant containment systems. These methods rely on a variety of new and classical optimization and modeling...
Description of the Application of Goal Programming for Selective Withdrawal Structure Operation
Thermal stratification in reservoirs results in variations of water quality with depth. Selective withdrawal structures with outlets at different vertical locations, can be used to provide...
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...
Plate and Frame Membrane Air Stripping
This paper examines utilization of a plate and frame membrane air stripping system for the removal of volatile organic chemicals (VOCs) and radon from a water supply. Previous work explored...
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....
Rehabbing Bridges Under Traffic
Four urban examples demonstrate how an owner's decision to keep it open during rehabilitation construction forces the designers to contend with an extra set of problems. Reanchoring...
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 League of Their Own
New baseball stadiums in Cleveland and Arlington, Tex., opening in April 1994, combine the nostalgia of traditional ballparks with state-of-the-art site planning and structural engineering....
Microsurfacing Urban Pavements
A European maintenance technique called microsurfacing can add years to the service life of cracked, ravelled pavements--with minimal interruption to traffic and for less than half the...
