Analyses of Sediment Transport Data by Microcomputer Software
The MINITAB statistical software project has been popularly used on mainframe computers since 1972. In June 1984, a subset of the program was made available for the IBM-PC microcomputer;...

Explicit Hydraulic Modeling of Sedimentation Transients in Alluvial Channels
An explicit finite difference numerical scheme is used in this study to model sediment transients in alluvial channels. The governing equations are momentum equation and continuity equation...

Water Distribution Systems Analysis and Graphics Using Microcomputers
In recent years, microcomputers have been increasingly employed in the analysis of water distribution systems. In addition to being used for hydraulic analysis, they can also be used to...

Computer-Assisted Problem Solving in Hydraulic Engineering
A number of practical hydraulic problems may be solved using software that allows interaction at the equation level rather than through higher level languages. This paper presents examples....

Microcomputers in Hydraulics-Hydrology Education
Microcomputer software is utilized for pipe network analysis, unsteady flow in pipelines, watershed modeling, flood studies, reservoir operations, dam break analysis, and groundwater systems...

Use of a Spreadsheet in a Water Distribution System Analysis
Spreadsheet programs such as MULTIPLAN can be used for many, if not most, of the small design oriented problems for which programs using high level programming languages such as FORTRAN,...

Applications of the Spreadsheet Multiplan and Equation Solver TK!Solver in Civil Engineering Education
General characteristics of the MULTIPLAN spreadsheet and the TK! SOLVER equation solver are discussed. Subjects covered include capabilities, rules and techniques for developing models,...

Data Acquisition in USACRREL'S Flume Facility
A computerized data acquisition system has been developed that is based on a Hewlett-Packard 9845B desktop computer. The system allows determination of highly accurate water temperatures,...

Computer-Based Data Acquisition, Analysis and Control: A Minicomputer System
The Environmental Fluid Mechanics Laboratory (EFML) employs two computer systems for the purpose of data acquisition, analysis and control. The first, an HP-2100 system, is used primarily...

Three-Dimensional Simulation of Flow, Salinity, Sediment, and Radionuclide Movements in the Hudson River Estuary
The three-dimensional, finite difference model FLESCOT was applied to a 106-km reach of the Hudson River estuary in New York between Chelsea and the mouth of the river. It predicted the...

Three-Dimensional Simulation of a Buoyancy-Driven Cavity Flow
The preliminary results of a numerical investigation of natural convection flow in a three-dimensional cavity heated from below are presented. The transient three-dimensional simulation...

Two-Dimensional Flow Visualization Using the Vortex Computer Code
A computer code has been developed to provide visualization of flow fields with regard to many hydraulic engineering design and analysis problems. The finite-difference computer code VORTEX...

Glen Canyon Dam Spillway Tests Model-Prototype Comparison
Between August 1983 and August 1984, model and prototype tests were run on the spillway of the Glen Canyon Dam. The tests were used to design and evaluate the performance of the aeration...

An Infiltration Based Runoff Model For Use With a Design Store
The feasibility of using an infiltration approach for routine runoff prediction has become a reality with the development of approximate infiltration models based on physical principles...

Secondary Circulation Data Acquisition System
A computerized field data collection system was developed for a project investigating secondary circulation in natural rivers. The instrumentation includes a Commodore mini-computer with...

Data Acquisition and Analysis of Pressure Fluctuations in Hydraulic Jumps
The paper reports on a study to procure basic data on large pressure fluctuations in hydraulic jump stilling basins. Interest in pressure fluctuations relates to: the effect of dynamic...

Macro Data Acquisition Systems on Minicomputers
Selection of the proper minicomputer for a real-time data system is a careful design process based on system requirements. Hardware should be purchased after requirements are set and not...

Computer Techniques for Acquisition and Reduction of Cross-Section Data
DuPage County, Illinois, has initiated a county-wide stormwater management program for planning and flood mitigation purposes. Field data with horizontal and vertical control are obtained...

Landfill Liner Hydraulics for Microcomputers
Two different models are presented for the study of sloping bottom liners for landfills. The first is based on the assumption that the leachate volume is uniformly distributed over the...

Water System Analysis?Modeling Hydraulics
The work described in this paper is part of the planning and design effort for expanding and improving the water supply system for St. John the Baptist Parish, Louisiana. The parish is...
