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...
Microcomputer Program for Daily Weather Simulation
Extensive climatic data have been collected by the National Weather Service and other agencies, and are available in printed form or on magnetic tapes. The published data are expensive...
A Microcomputer Program for River Sedimentation
Erosion and deposition of sediment in rivers causes numerous problems. In order to describe this process, both the hydraulic properties of the river and the mechanics of sediment transport...
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...
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...
The Micro vs. Mainframe in Hydrologic Modeling and Forecasting
This paper describes and compares the performance, application, and suitability of a microcomputer as host for the large-scale hydrologic model called SSARR. The SSARR Model is currently...
Flood Routing Through Rock Dumps in Natural Channels
The paper deals with flow through rockfill to analyze the problem of flood routing through large masses of waste rock from mining operations dumped in natural channels. Rock dumps in ephemerous...
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...
The U.S.G.S. Modular Ground-Water Flow Model: Designed to be Understood and Adapted
The paper discusses a carefully designed model program and its complementary complete description of all of the physical and mathematical concepts used in the model. The model program...
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...
SCS User-Defined Storm Hydrograph (SCS-USH)
The Soil Conservation Service User-Defined Storm Hydrograph (SCS-USH) has been developed to provide engineers and regulatory officials with a simple microcomputer tool for defining design...
A Quick Micro-Computer Urban Runoff Model
The Penn State Direct Hydrograph Model PSDH described in this paper uses watershed and rainfall data to generate a synthetic unit hydrograph and a runoff hydrograph, both gamma-distributed....
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...
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....
Design and Calibration of a 200-Foot Model Irrigation Border with a Computer Controlled Infiltrating Bed
A physical model of an irrigation border was constructed using a 200 ft long by 2. 5 ft wide tilting flume with a 3. 5 inch deep infiltrating gravel bed. The border was partitioned into...
Tidal Modelling on IBM Microcomputers
The finite element code, QUIET, for the simulation of two-dimensional shallow water flow has been adapted from its mainframe form for use on the IBM PC, PC/XT, or AT. The model uses of...
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....
Quick Stroking: A Fast and Accurate Algorithm for Time-Optimal Valve Closure Synthesis
In this paper, a fast, simple, yet effective technique for valve motion synthesis is developed. This technique called Quick Stroking is applied to a practical example problem, and it may...
