Telemetry Data Considerations in Water Systems Control
The installation of increasingly sophisticated telemetry systems for data collection within the water supply and distribution networks has progressed rapidly in recent years. This has...

On Obtaining Best Compromise Solutions for Municipal Water Use
Approaches to determine the 'best' use of available resources, including reuse of treated effluent streams have frequently relied on optimization techniques which...

Beyond Basic Modeling
Computers have long been used in water engineering to model hydraulic distribution networks In recent years, computer technology has exploded, yielding computers that are powerful and...

Optimal Operation of Multiple Reservoir Systems
In this paper a temporal decomposition approach is presented to solve a long term deterministic model for a multi-reservoir system. Through relaxation the long term problem is broken into...

Contributions of Satellite Imagery to Water Resource Evaluations
Satellite images may also facilitate the development and maintenance of regional Geographic Information Systems (GIS) by providing both a source of base map creation and update, as well...

Reservoir Operations by Fuzzy Goal Programming
The reservoir operations problem is composed of obtaining optimal releases, and storages of a reservoir and downstream reach routed flows based on forecasted inflows and precipitation....

Estimating Lake Inflows for Storage by Linear Programming
The Lower Colorado River Authority (LCRA) recently completed a Water Management Plan for the lower Colorado River Basin in Texas. In developing the Plan, a daily river flow routing procedure,...

Water Resources: Transfer of Development Rights
This paper addresses conflicts regarding development, land owners rights, accepted land development management practices, and community or public rights. It includes such issues as the...

Application of the GRASS Geographic Information System in a Sensitive Environment of the Arkansas River Navigation System
A Geographic Information System (GIS) was used to assist the selection of environmentally sensitive dredge material disposal sites along the Arkansas River Navigation System. Maintenance...

A Newsboy Approach to Real-Time Reservoir Operation Modelling
This investigation focuses on the use of mathematical programming techniques to develop a model for scheduling, in real-time, the releases from a single reservoir via a probabilistic approach...

Watermaster Administration of Texas State Waters
The State of Texas is developing a watermaster program which will enable the State to administer water right issues on a regional basis. A primary role of a watermaster operation is to...

Development of an Optimization Model for Groundwater Withdrawal
An optimization model has been developed to simulate optimal values of withdrawal from a given aquifer system. The linear programming technique has been used to formulate the objective...

Ship It By GIS
Abkowitz, Cheng and Lepotsky describe a GIS system for routing hazardous materials shipments. The safe transport of hazardous materials is emerging as a significant concern impacting local,...

Managing Water-Related Conflicts
the Engineer's Role
The problems facing water resources planners and managers are extensive. The major challenge is finding the key to cooperative rather than divisive approaches to water resources management....

Local Area Networks, a Hardware and Software Tutorial
The ability to develop, access and manage information has become a strategic component of a competitive and productive office. The capability to connect groups of microcomputers is now...

PC-Graphic Scheduling in a Multi-User Environment
This paper describes an approach used to implement a PC-based scheduling graphics system as part of a larger management information system installation at the Niagara Frontier Transportation...

Integrated Transit Network Analysis
As part of an update of the Boston, Massachusetts regional transit simulation process, the Central Transportation Planning Staff (CTPS) has implemented a microcomputer-based integrated...

ORNL Light-Duty Vehicles PC System
This data system, designed by the Oak Ridge National Laboratory (ORNL) and funded by the U.S. Department of Energy (DOE), monitors information on every light-duty vehicle (automobiles...

An Object-Oriented Strategy for Transportation Model Data
Data transfers between applications which require data from transportation models or inventories is an emerging problem. Recent advancements in software and software design have created...

Using SAF to Focus Mainframe Transportation Planning Data
This paper presents an overview of software called 'SAF' developed under FHWA sponsorship to assist in converting mainframe planning data sets into formats which can be input into microcomputer...
