Computer Usage in Obtaining Alternate Optimal Solutions for Water Resources Optimization Problems
In this paper, alternate optimal solutions of a few example linear programming problems are obtained by using a computer routine developed for the purpose. The routine is capable of generating...
Optimizing Nonpoint Source Pollution Reduction Costs
This study demonstrates diminishing marginal returns for spending to reduce nonpoint source pollution in Hampton, Virginia. A linear optimization program selected the best combination...
Optimization in Water Resources Planning
Recently developed optimization software represents significant first steps toward the application of the digital computer as a design and planning tool. This software has recently been...
Study of Stochastic Planning and Design of Multireservoir Systems
A new approach named Lumped to Discrete Programming (LDP) coupled with constrained stochastic optimization and successive approximation approach amongst reservoirs gives promise to subtantially...
Solving a State Environmental Agency Computer Maze
This discussion relates the experiences of a state environmental agency in addressing a decade of inadequate attention to the importance of computers and automated data processing to the...
The WSSC Integrated System Implementation Project
The software development effort conducted for the Washington Suburban Sanitary Commission began in October, 1981 and has been in process since that date. The goal of the effort is to produce...
Numerical Modeling of Groundwater-Lake Systems
Groundwater inflows can have important effects on the chemistry and biology of a lake ecosystem. For example, studies of lakes in Northern Wisconsin documented localization of ferromanganese...
Utilization of Numerical Models in Groundwater
For many years numerical models have been used in groundwater hydrology. In a recent assessment of the availabilty and use of models, a number of problem areas were identified. Some of...
Deterministic and Statistical Water Quality Modeling
An integrated methodology is presented, based on a hierarchical package of computer models ranging from simple micro-computer programs to more complex mainframe simulation, to address...
Estimating Delays at Navigation Locks
Tow delay is an important component of cost at navigation locks, and delay reduction is a major benefit of lock improvement. Computer simulation is a valuable method of estimating lock...

A micro-computer screening model was developed to analyze the physical and economic efficiencies of a large number of alternative options associated with a given water development project....
Large Scale Water Resources Systems Planning-Approach and Case Study
Planning approach for large scale water resource systems planning backed by models has been developed. Four hierarchial stages are identified and mulitlevel multiobjective models have...
Computer Model for Wastewater Reclamation
This paper describes how an efficient computer model can be constructed and used to evaluate planning options for wastewater reclamation. The situation in the City of Scottsdale, Arizona,...
Personnel Policies for Operations Management in the Computer Age
The human factor is an essential ingredient and the key element in successful computer applications for water resources or any other field. Engineers in general, and engineering managers...
Parameter Identification in Water System Models
Parameter identification (PI) is an automatic model calibration technique with which the unknown physical parameters in a mathematical model are determined from a constrained optimization...
Reliability Analysis of Urban Water Supply
The high economic and environmental costs of large water supply projects are forcing engineers to consider not only alternative means of increasing system reliability, such as interconnections,...
Hydraulic Profile Computation Using CADD
The data preparation can also be performed by directly recording onto a computer tape the aerial survey cross section ground points and the field survey work. A computer program can then...
