Closure of Hazardous Surface Impoundments and Creation of an On-site Permanent Disposal Facility?A Case History
Remington Arms Co. is currently undertaking a RCRA closure program for nine surface impoundments in Lonoke, Arkansas. The impoundments contain a variety of listed hazardous wastes from...

Hazardous Waste Impacts on the Highway Planning and Property Acquisition Process
Since the advent of increased public awareness concerning hazardous waste and the enactment of statutes governing these wastes, hazardous waste has become an important component impacting...

Computerized Data Processing, Displays and Groundwater Flow Analyses of the Stringfellow Hazardous Waste Site
Several types of data, maps, and figures were obtained from various sources involved in the investigations and monitoring at the site. This information was discretized, and a computerized...

Systems Approach for Irrigation Management of Complex Projects Involving Large Number of Farmers Under Severely Arid Regions
An Irrigation Management Information System (IMIS) was developed for complex irrigation projects involving a large number of farms under severely arid conditions. This system is a computer...

Interbasin Transfers: An Issue in Search of a Policy
Increasing demands for water combined with recent droughts have increased the search in many regions for new sources of water. High on the list of alternatives are always interbasin transfers....

Attitudes and Health Effects of Water Reuse
This paper is concerned with public attitudes toward water reuse for irrigation and with the consequences of human contact with reclaimed wastewater. Initially, attitudes are considered...

Who is the Public?
The old concept of applying to the state for a right to use water has changed as the availability of unappropriated water has disappeared. Today the emphasis is on acquiring a water right...

Advisory System for South Florida Water Management
A comprehensive, real-time advisory system was developed for the operation of water control facilities within the South Florida Water Management District. The Operations Assistant and...

Computer Support For TVA's Reservoir System Operations: Software
In the early 1980's, the Tennessee Valley Authority implemented its Water Resources Management Information (WATREMAIN) system to provide support for operation of its integrated multipurpose...

California's Adaptable Model for Operations Planning for the State Water Project
Operations of the California Aqueduct, a 440-mile-long feature of the State Water Project (SWP) consisting of canals, pipelines, reservoirs and hydroelectric plants, are planned using...

Role of Data Management in Water Control
The success of a system of software that must provide the water control user with current information, model analysis results, and forecasts of future behavior, is closely associated with...

Computer Program for Smoothing and Correcting Hourly Time Series Data
A FORTRAN computer program has been developed for the U.S. Army Corps of Engineers St. Louis District that automatically screens and corrects hourly time series data for gross errors and...

Development of the Hydrodata CD-ROM Data Storage System
To store and retrieve data from two of the USGS WATSTORE databases - the daily and peak values files - and the Summary of the Day file from the National Climatic Data Center, the authors...

Application of DDDP for Optimal Daily Operation of the Niagara Generating System
This paper describes the application of Discrete Differential Dynamic Programming (DDDP) to determine the optimal operation of Ontario Hydro's Niagara Generating System, on...

A Pilot Intelligent Decision-Support System for Reservoir Optimization
Various classes of knowledge used in reservoir design, planning and operations for improving the efficiency of the optimization processes are discussed in this paper. A prototype system...

Decision Support for Short Term Export Sales From a Hydroelectric System
A stochastic dynamic programming (SDP) model was recently developed and implemented at British Columbia Hydro and Power Authority (B.C. Hydro) to provide decision support for short term...

Use of Probabilistic Constraints in Reservoir Operation Policies With Sampling Stochastic Dynamic Programming
The role of mathematical simulation and optimization models in hydropower planning at Pacific Gas and Electric Company is discussed, and some of the models are described. Applications...

Application of Principal-Component Analysis to Long-Term Reservoir Management
Determining the optimal long-term operating policy of a multireservoir power system requires solution of a stochastic nonlinear programming problem. The paper presents a very efficient...

Stochastic Dynamic Programming Applied to Multireservoir Systems
The main goal of this work was to develop a large scale optimization algorithm incorporating the principle that the uncertainty of future events increases with time. This principle governs...
