Applicability of Groundwater Models to Microcomputers
Microcomputers represent a viable alternative to mainframe and minicomputers for the implementation of groundwater models. The criteria used to evaluate microprocessors are maximum addressable...
Three-Dimensional Simulation of Two-Fluid Movement in Porous Media Using the Boundary Element Method
The paper discusses three-dimensional problems that include a denser fluid overlain by water in an unconfined aquifer. The two fluid regions are bounded by two-dimensional surfaces, including...
Electronic Worksheet Applications in Hydrology and Hydraulics
Spreadsheet software packages are available for virtually all micro computers in use today. Although they are quite often thought of as business tools, their usefulness as engineering...
Automated Measurement of Soil/Water Properties
An automated data-acquisition system was constructed to permit continuous operation of laboratory equipment. The apparatus was used to monitor flow through fine-grained, 'undisturbed'...
A Low-Cost, Microcomputer-Based Field Data Acquisition System
This paper discusses the selection and development of a micro-computer-based data acquisition system used for collecting aquifer test data. Primary components of the data collection system...
Microprocessor-Based Data Acquisition Systems
The application of microprocessor-based data acquisition systems to laboratory experiments and field tests is discussed. The importance of the system design and hardware selection is emphasized....
IIHR's Data Acquisition Systems and Their Applications
The Iowa Institute of Hydraulic Research (IIHR) has recently experienced rapid growth in number of experimental studies, in number of buildings housing these models, and in the diversity...
The Matched Artificial Dispersivity Method
The paper presents a class of models that are well-suited for microcomputing and that are based on what may be called the 'Matched Aritifical Dispersivity' method....
Analytic Solution for Seepage from Saturated Soil Behind a Braced Wall
The locations of streamlines and equipotentials for two-dimensional flow in the vertical plane normal to a vertical retaining wall can be determined by various methods. Recent extension...
Microcomputer Graphics Flood Stationarity Test
Only records that correspond with present river conditions should be used with flood frequency analysis when forecasting. A microcomputer test is discussed which aids in selecting appropriate...
Flood Peak Program for Urbanizing Semi-Arid Areas
This paper describes a microcomputer program for flood peak determination based on a highly modified version of the Rational method developed by M. E. Zeller, which employs the Soil Conservation...
A Microcomputer Based Real-Time Flood Warning System
A microcomputer based real-time flood warning system is being developed as an event monitoring and early warning system for local areas. The system consists of a micro computer based central...
Cazenovia Creek Model Data Acquisition System
The purpose of the model is to reproduce river ice breakup phenomena for optimizing the design of an ice control structure. The performance of the ice control structure during a simulated...
Instrumentation for an Uplifting Ice Force Model
Pile-supported, light duty structures are especially vulnerable to the uplifting forces. To evaluate the parameters that control the magnitude of the uplifting force a laboratory model...
Data Acquisition and Control for Hydraulic Models
The Waterways Experiment Station is expanding the use of computer controlled data acquisition and control equipment on a variety of hydraulic models. These systems are presently being...
Near Real-Time Climatic Data in Illinois
The need for making real-time climatic data available for use was recognized in Illinois, and a concerted effort began in 1983 to develop a system for collecting and disseminating near...
Automated Analysis of High Accident Locations
Identification of high accident locations and associated accident causative factors as well as determination and evaluation of appropriate remedial measures at these sites are continuing...
APM System Performance and Guideway Design Parameters
Automated People Movers (APM) are a relatively new form of transportation system becoming popular over the last twenty to twenty-five years. They are characterized by fully automatic and...
Investigation of Design Criteria for APM Guideways
Designers have relied mostly on the provisions of the American Association of State Highway and Transportation Officials (AASHTO) Standard Specifications for Highway Bridges. Sometimes...
The Possibility of People Mover Cost Reduction in Japan
One of the major problems preventing the introduction of people movers into urban areas is their expensive unit cost in comparison with existing transport technologies. In this paper,...
