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...

Computerized Operation of California State Water Project
Hydraulic and electrical schedules for the California State Water Project are determined and dispatched from the Project Operation Control Center (POCC) in Sacramento. The dispatched schedules...

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...

Optimal Operation of a System of Lakes for Quality and Quantity
A methodology is presented combining simulation and optimization techniques for determining operation strategies for a system of lakes in the presence of quality and quantity constraints....

Modeling of Reservoir Operations for Managing Ecological Interests
A network simulation model is applied to a three reservoir system to analyze the effects of alternative operating policies in response to such seasonal water demands as hydropower, pollution...

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...

Practical Optimization of Looped Water Systems
This paper describes one tool that might be part of a package to assist a design engineer in sizing pipes, determining ideal locations for booster pumps and their heads, determining heads...

A Methodology for Optimal Network Design
A methodology is developed to optimize the design of water distribution networks using reduced gradient techniques with a network simulator. The problem is reduced in complexity by incorporating...

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...

Program Monitoring by Database Management
Management of the water resources programs of the Army Corps of Engineers, with its 3 billion annual budget, 27,000 employees, and decentralized organizational structure, is obviously...

Microcomputer-Based Monthly Treatment Reporting
Massachusetts wastewater treatment plants must file monthly operating reports with the Massachusetts Division of Water Pollution Control. A microcomputer-based monthly reporting system...

Real-Time Reservoir Operations by Quadratic Programming
A quadratic programming model is developed for real-time reservoir operations. It is assumed that convex penalty functions that relates the deviations of storage levels and downstream...

Great Lakes Water Diversion: Legal Issues
This article deals with state/provincial, regional, federal and international legal issues involved with protecting Great Lakes water. First, the article describes the institutions and...

Multi-Objective Planning: Great Lakes Water Policy Issues
This paper reports upon the development of computer algorithms for multi-objective planning for Great Lakes water policy issues. Sample applications are presented for the control of phosphorus...

Legal Constraints on the Transport of Water
Legal constraints on water transport are based on legitimate concerns for protecting the future interests of the area of origin, but such constraints sometimes appear overly restrictive...

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...

Prior Information in the Geostatistical Approach
An overview of recent work on the geostatistical approach to the inverse problem of groundwater modeling is presented. A method which allows utilization of prior information about the...

Forecasting Water Use: A Tutorial
In spite of 4,000 years of public water supply system construction, designs have been customarily based on forecasts of future water use only during the last 100 years. Choices among available...
