Estimating the Energy Rate Function for Hydro Power Production Optimization
Operations planning at Manitoba Hydro is aided by using the Energy Management and Maintenance Analysis (EMMA) computer program. EMMA is a Linear Programming (LP) based model with the objective...
A Travel Time Template for Water Body Field Surveys
A LOTUS 1-2-3 spreadsheet application has been developed to help plan water body surveys. The template calculates travel times between sampling stations and outputs a time schedule for...
Simulation of a Surface Water Allocation System
This paper outlines the water rights system in Texas and a newly developed computer simulation program for modeling this system. In addition, an overview of a river basin simulation using...
History of Geographic Information Systems, with Applications in Water Resources Planning and Management
Elements of computerized spatial analysis have been used in water resources since the mid '60s, and sophisticated and complex systems incorporating geographic information...
The Present of GIS
A review of geographic information systems (GIS) as a spatial database is presented. Computer aided design and relational database features of GIS are explained, as well as possible types...
Applying a Simple GIS to PMP Analysis in a Microcomputer Environment
The analysis of probable maximum floods (PMF) in the Northwestern United States requires the inclusion of a snowmelt component combined with probable maximum precipitation. Traditionally...
Meta-Site: Water Distribution System Analysis Software
Many local municipalities now require a network analysis for all proposed additions to their water distribution systems. A graphically oriented, user-friendly program is being developed...
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,...
Is There a Future for Vacuum Sewers?
Vacuum sewers collect and transport sanitary sewage using pressure difference rather than gravity as the primary motive force. Compared to conventional gravity sewers, they use smaller...
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...
Groundwater Quality Network Design
This paper presents a methodology that uses optimization for designing a groundwater monitoring network. The methodology incorporates parameter estimation in conjunction with a numerical...
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...
