Adapting a Pipe Network Analysis Computer Program
The Metropolitan Water District of Southern California (Metropolitan) has developed a mathematical simulation model for a key portion of its distribution system. A representative portion...

Computer Modeling of Distribution System Water Quality
The WADSY-Q computer program was developed as a tool to analyze water quality patterns in water distribution systems with multiple sources. The program calculates the concentrations of...

Optimization of Looped Water Distribution Networks
The optimization algorithm developed by G. Quindry et al. can be used to obtain a least cost pipe network for a looped water distribution system. A solution is obtained under steady state...

Pipe Network Optimization by Enumeration
The paper describes a procedure for the optimization of pipe networks which is executed entirely in the discrete pipe size/cost domain. The technique is based on exhaustive enumeration....

Modeling Water Resources Systems for Water Quality
A reservoir system analysis computer model has been recently developed with the capability to simulate up to 10 reservoirs, 30 control points and 8 water quality parameters. With this...

OPNET: A Nonlinear Design Algorithm for Hydraulic Networks
The author has developed a general computer program OPNET to be used in the optimal design of hydraulic networks. The computer program can be used to optimize three basic variables; tank...

Data Transforms on USGS Surface Water Records
Surface water records compiled and stored by the United States Geological Survey (USGS) on machine readable tape are transformed and analyzed by computer methods to enable visual inspection...

Real-Time Data Verification
Recent improvements in the real-time acquisition of hydro-meteorological data have raised concerns regarding the quality of the data received. Water users having practically instant access...

Computerized Design and Selection of Pumping Systems
Three computer models have been applied in the evaluation, design and selection of a high-lift pump station upgrading program developed for the City of Poughkeepsie, New York. The three...

Storm Sewer Computer-Aided Design and Uncertainty
A micro-computer based storm drainage model is presented which facilitates urban storm sewer design on fast tracked construction projects. The model is an interactive Basic program using...

Conceptual Framework for Regression Modeling of Ground-Water Flow
The author examines the uses of ground-water flow models and which classes of use require treatment of stochastic components. He then compares traditional and stochastic procedures for...

Forecasting Demand for Urban Water
The purpose of this study is to assess current water use forecasting practice in the US Army Corps of Engineers and to recommend additional approaches which best satisfy current requirements....

Practical Water Demand Forecasting
The authors describe their experience in designing, building, and applying a water demand forecasting model for the Denver metropolitan area. In the presence of incomplete and sometimes...

Tampa Bay 205J Water Quality Impact Study
Tampa Bay was identified by the State of Florida Department of Environmental Regulation (FDER) as to the top priority for an impact study using federal 205(j) grant funding. The study...

Optimization of Flood Control Projects
Project optimization analysis techniques have become indispensable tools for the design, management, and administration of flood control improvements. The increasing complexity of engineering...

Optimizing Nonpoint Source Pollution Reduction Costs
This study demonstrates diminishing marginal returns for spending to reduce nonpoint source pollution in Hampton, Virginia. A linear optimization program selected the best combination...

Micro-Computer Water Develoment Screening Models
A micro-computer screening model was developed to analyze the physical and economic efficiencies of a large number of alternative options associated with a given water development project....

Hydrologic Work Group System Using Distributed Task Processing
The notion behind work group systems is that a collection of co-workers, numbering from a few to a few tens of people, is the logical unit around which to build a centralized microcomputer...

Hydrograph Decomposition: Using a Technical Database
Trouble shooting for infiltration/inflow (I/I) problems in a sewer system is made much easier with the aid of a computerized hydrograph decomposition methodology. A methodology has been...

The SRI Technique for Flood Frequency Analysis
This paper presents a technique for flood flow frequency analysis called the Storm Response Index (SRI), and a case study using the technique. The SRI method is based on the development...
