Reservoir System Simulation Through Network Flow Programming
A generalized reservoir system simulation model that makes use of a network flow programming technique has been developed for use in planning and operation studies of multi-purpose water...
Facilities Planning in the Caribbean a Case Study
Culebra has significant problems of water scarcity and poor wastewater treatment. In 1984-1985, a formal Environmental Impact Statement (EIS) was prepared for improved wastewater treatment...
Modeling to Generate Alternatives: A Review
Modeling to generate alternatives (MGA) is a species of multiobjective programming in which some relevant objectives and perhaps some constraints are deliberately left unquantified. The...
Integrating Policy Factors in Stream-Aquifer Models
One of the main issues appearing today in the field of water resources is the management of complex hydrologic systems consisting of surface streams and aquifers. The management problem...
Ground Water Strategy in California
There is great debate over when and how much new water California needs. Yet of the backbone supply, wells that could serve over 1 million people have been either removed from use or blended...
Policy Issues in Managing Nonpoint Source Pollution
Attention is first given to the extent of the right of the landowner to generate contaminated runoff. The previously recognized privilege of landowners to make point source waste discharges...
Project Cost Control for Heavy Equipment
Some concepts and methods of project cost control for heavy equipment have been defined, which include methods, effectiveness, outside repairs, and the resulting management information,...
Solving Nonlinear Equations on a Hypercube
Certain classes of nonlinear systems of equations, such as polynomial systems have properties that make them particularly amenable to solution on distributed computing systems. Some algorithms,...
Lessons Learned from Design, Construction, and Performance of Hydraulic Structures
The intent of this publication is to provide lessons learned, both positive and negative, from activities associated with design, construction, and performance of hydraulic structures....
Water Project Design and Safety: Prospects for Use of Risk Analysis in Public Sector Organizations
After offering some initial definitions, the authors will describe a highly structured model of risk analysis and water resources decision making in the public sector. The primary emphasis...
Approaches to Acceptable Risk
Acceptable risk has numerous meanings, that are derived from its having been defined in multiple arenas and by multiple groups. This paper describes several approaches to the question...
The Credibility of Probabilities: An Application to Water Resources Policy
This paper focuses on one particularly troublesome issue in decision analysis, the issue of the credibility of subjective probabilities. A water resources policy problem is used to illustrate...
Methods for Real-Time Control of Highway Traffic
The paper describes the development of computational strategies for demand-responsive decentralized traffic signal control. First, a Dynamic Programming procedure is developed which serves...
Transportation Infrastructure Information Systems
The current crisis in the nation's transportation infrastructure necessitates the development of innovative data management systems to facilitate and implement analysis algorithms...
The Metropolitan Boston Area Earthquake Loss Study
This study develops an inventory of critical facilities in the Metropolitan Boston area and analyzes the impact of a project earthquake (Cape Ann Event) on their structural integrity and...
Lifeline Risk Analyses: The Mokelumne Aqueduct Study
Probabilistic risk analysis methods are applied to the evaluation of seismic and non-seismic vulnerability of a 25-kilometer length of a major lifeline aqueduct system. In addition to...
The Broad Spectrum of CM Services
The Construction Management system has developed to the point where all Construction Management tools are available to the industry. These tools fall into the general categories of computer...
Hydrologic Modeling Using Radar-Rainfall Imagery
A flash flood forecasting system is being developed which has three main elements: 1) high resolution estimation of rainfall in time and space using radar and ground-based gages; 2) computer...
A Microcomputer Reservoir Decision Model
The paper discusses the development of a dynamic programming model to optimize reservoir operations. Given statistical summaries of inflows, forecasts of near-term inflows, and cost statements...
Application of Lotus Symphony in Water Quality Modeling
The spreadsheet capability of the Lotus Symphony program package was used to simulate the dissolved oxygen dynamics in streams and rivers. 'Windows' were created...
