Living with a Macintosh in an IBM World
The Macintosh computer is widely praised for several characteristics: high resolution graphics, common program user interface, user friendliness including extensive use of a mouse, and...

Making Microcomputer Based CADD Systems Productive
The introduction of microcomputer based CADD systems has made CADD affordable to small engineering firms. Many have not been able to make their CADD system productive. The sources of poor...

Using the Microcomputer in the Software Development Process
The migration of the computer from the controlled environment of a computer room to the office desk-top provides the software engineer with a convenient and effective tool for enhancing...

Water Distribution Systems Analysis Package
A computer software package for water distribution systems analysis has been developed for the city of Fort Worth, Texas, to overcome the problems of time consumption and human error,...

Methodology for the Optimal Reliability Based Design and Analysis of Pumping Systems for Water Distribution Networks
A methodology has been developed for the optimal (minimum cost) reliability based design of pumping systems. Two computer simulators, a reliability simulator and a hydraulic simulator,...

Optimal Pump Operation Using Nonlinear Programming
This paper focuses on the operational control problem of determining the optimal pump operation policy for a given distribution system. The optimal pump policy is defined as that schedule...

CADD Applications in Water Resources Design
CADD can provide substantial benefits, in terms of speed and ease of revisions, in the design of civil engineering projects, including water resources facilities. However, current design...

A Linear Dynamic Programming Model for the Optimal Allocation of Water in Groundwater Dependent Areas
The purpose of this paper is to describe an efficient computer-aided planning method using linear and dynamic programming together with a finite difference groundwater model to determine...

A Ground Water Modeling Effort to Simulate the Results of An Aquifer Restoration Scheme
A ground water model using the IBM PC version of the USGS MODFLOW code was constructed to simulate the ground water flow beneath an industrial site in the central Midwest. A detailed three-dimensional...

TRUMPET: A TR20plus Watershed Model?Version 1.04
The TRUMPET watershed model is a microcomputer application which expands upon the widely used SCS TR20 hydrology computer program by providing user-friendly, interactive input and file...

Comparison of Two Methods for Modeling Urban Runoff
The techniques currently available for modeling urban runoff can generally be grouped into discrete and lumped system approaches. The storm water management model (SWMM) provides procedures...

Terrain Modelling for Computer-Aided Site Development
This research proposes a terrain model and a storm drainage model to be used as tools in creating a more efficient design/approval stage of the development process. This research proposes...

Daily Water Budget Model for Water Resources Management
A daily water budget model has been developed and tested for the Clinch and Powell watersheds located in SW Virginia and NE Tennessee. The model integrates available data and simulates...

Computerized Bridge Coding for HEC-2 Applications on I.B.M. P.C.
A computer program for conversion of survey field notes directly into SB, BT, and GR cards with simultaneous cross-section plot is described. It was designed to simplify the coding of...

An Investigation into Causes of Bank Caving
A series of investigations into bank caving along the Ohio River are described. These investigations include a study of the distribution of precipitation in the study region, derivation...

Water Conservation and Floodplain Regulation at Barrett Dam?San Diego, CA
Barrett Dam is owned and operated by the City of San Diego, California. This paper describes the response of the dam to heavy storms that occurred in Southern California in 1980. Computer-generated...

Forecast Uncertainty in Reservoir Operation
Bayesian decision theory can be of significant value to reservoir operation because of its flexibility in being able to incorporate new information and/or opinions and judgments of decision...

Water Demand Forecasting in Southern California
A study of annual water use in Southern California is made in order to determine the cause of unusually high demands in 1987. Regression analysis of the demands and analysis of ratios...

Use of Stormwater Models to Optimize the Performance of a Regional Stormwater Detention System
implications of stormwater models to develop a regional detention basin master plan for Fairfax County, Virginia are described. Following the selection of candidate sites and detention...

Floodplain-Management Plan Enumeration
A branch-and-bound enumeration procedure can improve the search for an optimal floodplain-management plan. The procedure compares the net benefit of all possible combinations of proposed...
