Using a GIS to Better Manage Water Resources in Texas
This paper examines five GIS applications under development in two state agencies in Texas responsible for the management and regulation of water resources, response to and remediation...
Heuristic Optimization of Water Distribution Systems
A design heuristic for the optimization of water distribution systems is presented. Algorithm TREESEARCH finds a near optimal core tree layout. Algorithm REDUNDANCY adds redundant links...
An Alternate Formulation of Time as a Decision Variable to Facilitate Real-Time Operation of Water Supply Systems
With the advent of a new focus on energy conservation and the availability of cost efficient computer technology, many water utilities are investigating new ways to improve the efficiency...
Case Studies on the Use of Semi-Standalone Control Loops for the Management of Regional Public Water Supply
The West Coast Regional Water Supply Authority is charged with the operation and management of the public water supply that serves over 1 million people in the Tampa Bay Area of Florida....
Network Modeling in a Water System with Ferrous Deposits
This paper presents the experiences and results of a network modeling study. A model for the University of Idaho water supply system was developed and verified to the extent possible with...
A Comprehensive Algorithm for Network Calibration
An explicit calibration algorithm is proposed which provides the direct and rapid adjustment of the pipe roughness coefficients and junction node demands that exactly meet a specified...
Water Supply Network Modeling for Infrastructure Management
The concept of a graphics-based computer package for water supply network modeling and system management is discussed. Network model input and solution data are reported via color graphics...
An Expert Critiquing System to Assist in Operating a Water Supply Network
An expert 'critiquing' system is under development to assist in operating San Francisco's multi-reservoir water supply system. This computer application...
A Logical Variable Approach to Water Supply Reliability
The calculation of the reliability that water will be available at a demand point in a distribution network is complicated by the redundancy of paths from the source to the point. The...
A Water Information System for Decision Support in Design, Operation and Management of Distribution Systems
The design, operations and management of water supply and distribution systems require considerable amounts of data and data processing and analysis. What is not available to the water...
Managing Water Supply and Demand with Integrated Computer Models
Water resource planning and management has greatly benefited from the use of computer modeling. Numerous computer models have been developed to predict expected outcomes given a set of...
Optimizing Urban Ground Water Supply Systems
The cost of Pumping comprises a major part of total water operation and maintenance expenses. Most utilities attempt to keep these costs down. However, there are areas of study that may...
The State of Nevada Operational Seeding Program
Integration of the Nevada Operational Weather Modification Program into management of the region's water supply is a key element to meet the increasing demands placed on these...
Rehabilitation of Water Distribution Systems Planning and Implementation
The paper describes the approach taken to develop infrastructure rehabilitation procedures for Water Distribution Systems. Early research attempted to develop a mains condition oriented...
A Decision Support System for Water Supply Costing
Accurate cost estimates for water supply system expansions are an important component of the planning process. A spreadsheet-based cost estimating model called SWFCOST was developed as...
Design of a Neural Network Power Grasp Controller
An overview of research on the development of an artificial neural network controller used to implement power grasping on the DIGITS Grasping System is presented. The DIGITS System, under...
On the Transformation of Wave Spectra by Currents and Bathymetry
Application of the conservation principle for action spectral density along rays, frequently described in literature, is not sufficient to specify the refracted wave spectrum. In order...
Computation of Flow Fields Induced by Hydroplant Releases into Lower Lock Approaches
A turbulence-based computational procedure was developed and applied to the prediction of flow fields in navigation installations induced by hydropower releases. The procedure uses a depth-averaged...
Structural Responses in Mechatronics
The design analysis of a circular cylinder, ring-stiffened intermittently, subject to conducting flow, is presented herein (Fan, 1986 & 1990). This composite cylinder is made of...
Large Deflection of Simply Supported Inplane Loading Rectangular Plate Under Uniform Random Pressure
