An Analysis of the Impact of Weather Variation on Monthly Water Demand
A methodology is utilized to analyze and model the impact of weather variation on monthly long distance water deliveries in Southern California. Monthly water demand is viewed as a combination...
Water Utility Demand Forecasting Using Lotus 1-2-3 Spreadsheet
In this study, a technique has been developed using Lotus 1-2-3 spreadsheet for distributing projected populations to small sectors throughout the study area. This procedure divides the...
The Multi-Watfore Method: A Water Demand Forecasting System
The multi-Watfore method, which combines the cascade model and a first order analysis of uncertainty, is a system of practical steps to develop models of water demand while generating...
Real-Time Optimized Control of a Water Distribution System
The paper presents the design of a fully automated real-time computer control scheme for least cost operation of a water distribution system. The scheme includes modules for optimized...
Water Reuse in Las Colinas, Irving, Texas
The largest urban water reclamation project in Texas that involves reuse of treated wastewater was implemented in July 1987, to provide an economical and drought-free supply of water to...
The Use of the IWR-Main System as a Planning Tool in Phoenix, Arizona
The IWR-MAIN water demand forecasting model is used extensively as a long-range planning tool by the Phoenix Water and Wastewater Department. Its specific applications include: conservation...
Conductivity and Transit Time Estimates of a Soil Liner
A field-scale soil linear was built to assess the feasibilty of constructing a liner to meet the saturated hydraulic conductivity requirement of the U.S. EPA (i.e., less than 1 ? 10-7...
Focused Model Approach for Corridors and Subareas
A focused modeling approach utilizes calibrated model parameters and inputs from a regional model, yet allows the flexibility to quickly test land use, network and other policy alternatives....
A Package for Travel Demand Forecasting on The Macintosh
This paper introduced a package which may be the first to be developed for travel demand forecasting on the Macintosh. Features of the package and its capabilities are demonstrated through...
Microcomputer Capabilities for Trip Table Estimation and Peak Hour Assignments which Consider Peak Spreading
The microcomputer-based TRANPLAN transportation planning package has been expanded to include a trip table estimation procedure and an equilibrium traffic assignment model which simulates...
Microcomputer Assisted Transportation Impacts Analysis: Hudson River Waterfront Development
Across the Hudson River from Manhattan, major office and residential developments are occurring on large tracts of former railroad and shipping properties in New Jersey. Much of this development...
Using Lap Tops as Connections to Minicomputers in the City of Portland
Over the past few years, the City of Portland has used a mix of personal computers and minicomputers to accomplish its mission. This paper describes four applications of using lap top...
Synthetic O-D Microcomputer Trip Table Packages
Three microcomputer models for synthetic estimation of origin-destination trip tables are compared based on theoretical foundations, implementability, and operating performances. Each...
InTransit: Processing and Analyzing Transit Service Data with the Macintosh
InTransit is a database application based on 4th Dimension designed to facilitate the data processing and analysis phases. InTransit, in its present form, can process both ridecheck and...
Processing Automatically Collected Patronage Data
Since the late 1970's, the San Francisco Bay Area Rapid Transit District (BART) has had the capability to automatically collect trip origin and destination data from its faregates. This...
Advances in Trip Matrix Estimation
The derivation of Origin-Destination (O-D) trip matrices is a vital component of much transportation planning. Obtaining accurate O-D data often poses a challenge on account of the large...
Computer Analysis of Origin-Destination Survey Data in the State Route 55 Travel Corridor, Before and After the Opening of Carpool Lanes
The State Route (SR) 55 carpool lanes in Orange County were opened for high occupancy vehicles (HOV) usage in November, 1985. Since SR 55 was the first travel corridor in Orange County...
Dynamic Assignment Modelling with Trips
This paper describes additional ways in which TRIPS models time-varying, or 'dynamic' effects. These include area-wide effects as vehicles move through the network,...
Advection-Diffusion Calibration of Dissolved Oxygen
Modifications of J.J. Leendertse's water-quality model for improving calculations of dissolved oxygen concentrations in Jamaica Bay, New York, are discussed. Changes to the...
Procedures Used for Determining Water Rights on the Caribbean National Forest
