A Language Model for Space Construction Control
The optimal construction system for many space construction projects is a mixed construction ensemble. Such an ensemble consists of humans, robots with varying degrees of teleoperation...

New Technologies for Unmanned Space Exploration
There could be no better time than now for the development and implementation of new technologies such as V.L.S.I. and optoeraseable storage. Creative inventions from new mathematical...

Optimal Control Strategies for Water Distribution Systems
The overall operation problem becomes one of determining which pumps to run and when to run them so that electrical unit costs and electrical demand charges are minimized while at the...

A Methodology for Optimal Control of Pump Stations
Pumping water to utility customers is an expensive service which consumes large amounts of energy. Most approaches to date require simplifications and assumptions for the specific system...

Remote Infrared Thermal Sensing of Sewer Voids
The question addressed by this paper is how to detect unseen problem areas in sewer systems before they give way. At present, progressive sewer administrations may use crawl crews or television...

A Water Pricing Model for Lake Texana
Faced with water sales and recreation revenues insufficient to service the project debt, the Lavaca-Navidad River Authority (L-NRA), operators of Lake Texana, decided upon a novel approach...

Optimal Real-Time Operation of Te-Chi Reservoir
An optimization model for the 10-day operation of Te-Chi Reservoir in central Taiwan is developed. The inflow to the reservoir is forecasted by an ARX model with a Kalman Filter updating...

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...

Stochastic Optimization of Conjunctive Use in Pakistan
This paper describes an optimization analysis of conjunctive use of ground and surface water that incorporates stochastic inflows and regional variations in groundwater quality and availability....

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,...
