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...
Possum Kingdom Lake: The Impact of Releases for Fish and Wildlife
Possum Kingdom Lake is a 570,000 acre-foot reservoir on the Brazos River in Palo Pinto County, Texas, owned and operated by the Brazos River Authority (BRA). In 1985 the BRA applied to...
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...
Economic Benefits of a Flood Warning System?The Ventura County, California Experience
Since the spring of 1979, Ventura County has been receiving the benefits of a growing Flood Warning System (FWS). Beginning with six self-reporting raingages, two untested flow models,...
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,...
Design of Sampling Networks for Water Table Monitoring
In the application to the monitoring of water tables the presence of temporal and spatial dependence is of crucial importance. Often the network will be used to collect data to estimate...
Advances in Hydraulic Stream Modeling Using HEC-2
The Corps of Engineers, Ft. Worth, Texas, Flood Plain Management Services Branch has developed hydraulic stream models for creeks and rivers throughout the state of Texas for the purpose...
Identification of Aquifer Parameters in Confined Groundwater Flow
The logarithm of the aquifer properties, log transmissivity (log T) and log storativity (log S), are regarded as realizations of stochastic processes whose estimates are required. The...
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...
Streamflow Prediction and Allocation Model in Texas
The State of Texas' Water Rights Adjudication Act of 1967 provided for the creation of regional watermasters to divide the water of state streams in accordance with the adjudicated...
Flownets by Computer Graphics
A new method of drawing flownets for determining seepage losses in earth dams is developed. The flow and equipotential lines are drawn by modifying W. Kinzelbagh's method....
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...
The Center for Advanced Decision Support for Water and Environmental Systems
In July of 1988, the US Bureau of Reclamation awarded the University of Colorado a 4 year, 4 million dollar Cooperative Agreement for the development of a Center of Excellence in the Application...
Managing the Introduction of New Technologies: An A1 Case Study
The way in which a new process or product is introduced into an organization can be critical to its acceptance and successful implementation. Even if the innovation is a major technical...
Creating a Transportation Microcomputer User's Group in Mid-Michigan: Organizational Issues and Opportunities
This paper describes the Mid-Michigan Transportation Microcomputer User's Group. Purposes of the User's Group include promoting demonstrations and evaluations...
How Microcomputer Transportation Networks Can Shift Institutional Relationships Between Governmental Agencies
This paper describes the current institutional and microcomputer relationships in the Portland, Oregon metropolitan region; identifies how emerging microcomputer linkages have affected...
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...
Electronic Communication and Data Transfer: Productivity Enhancements
Large ventures operating from widely separated sites cannot depend on local area networks for their communication requirements, as can small, single-sited projects. Not all projects have...
