Stochastic Simulation of Streamflows
In order to provide a better method of generating synthetic streamflow data, a stochastic model of simulating long-term streamflows is developed. Basically, this method uses historical...
Applications of Spreadsheets in Water Resources
This paper describes two applications of the spreadsheet MULTIPLAN to water resources problems. Applications include statistical analysis of water resources data and design of a stormwater...
Microcomputer Analysis of Harbor Wind Drift
A microcomputer with general-purpose spreadsheet software was used to analyze wind drift on the water surface of Quincy Bay in Boston Harbor. Wind drift is the movement of the surface...
Analysis of Unsaturated Flow Beneath a Landfill
Using the linearized theory of flow in unsaturated porous media, a mathematical model was developed to study the distribution and extent of unsaturated flow from a source of infiltration...
Software Authoring for the Rest of Us
Extensive use of high resolution graphics, form-oriented full screen data entry, and contextual help messages have proven to be an effective means of structuring the dialogue between the...
Analysis of Drinking Water Systems: A Spatial Approach
This paper describes recent examples of spatial analyses as (1) a unifying concept for allocation of costs to various elements of water treatment and delivery; (2) a link and node (Network)...
Automated Data Monitoring for Disaster Prevention
A system is now available from International Hydrological Services for use on micro-computers that will provide real-time environmental monitoring, analysis, forecasting and control. This...
Water Information Available from the U.S. Geological Survey
As a part of the Geological Survey's program of releasing water data to the public, two large-scale computerized systems are maintained. The National Water Data Storage and...
Computer Applications for Real-Time Operation of Water Distribution Systems
This paper surveys the state-of-the-art in computer assisted real-time operation of water distribution systems. It first examines the reasons and justification for installing computer...
Time Series Analysis of Hourly Domestic Water Demand
Design flows for water supply and sanitary sewer systems are chosen by rules of thumb in the absence of actual data. This research develops two stochastic models of water demand by analyzing...
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...
Water Data Bank of the Hashemite Kingdom of Jordan
The Hashemite Kingdom of Jordan and the United States of America have jointly undertaken an investigation of the ground-water resources of Northern Jordan. An initial step in the investigation...
State-of-the-Art Design of Databases for Water Related Data
This paper presents an overview of techniques for design and application of databases to water related data. The intent is to introduce new concepts to the practicing engineer who has...
Yakima Supervisory Real-Time Monitoring and Control System
The Yakima Remote Control System is a case study application of supervisory control and data acquisition (SCADA) concepts for the operation and monitoring of a large water resources project....
Computers: Water Resources Models in Latin America
Ninety-six national institutions dealing with planning, irrigation, water supply, and hydropower generation in twenty-six Latin American and Caribbean countries were surveyed between February...
Hydrological Database Management
Development of hydrological database management is investigated in this study. Lotus 1-2-3, a commercially available database, which makes use of spreadsheet has been used to solve a broad...
Automated Data Collection for Reservoir Regulation
Various regulation changes in the Lake Winnebago basin have been proposed regarding the protection of wetlands and assurance of adequate outflows for water quality. To implement these...
Successive Application of Reservoir Simulation Models--A Case Study
Replacement of the conventional method of generating hydrology by a well established reservoir simulation model renders enormous amounts of flexibility and savings in computation time....
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...
