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...
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...
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...
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...
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...
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...
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...
