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...

Personal Computers and Water Network Simulation
The advent of the 16 bit or larger personal computer has the potential for significantly increasing the availability of a powerful tool for hydraulics engineers. In the past, the understanding...

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....

Hydro Power Intake Design?Criteria and Experience
This paper briefly addresses parameters to be considered in hydro power intake designs. Included are design approaches and criteria, specific examples, and applicable references. Concerns...

Intakes for Low Head Hydro Plants
The design of hydro intakes is usually based on a desire to achieve low intake losses and an acceptable approach flow distribution to the turbine. Generally, velocities in the intake canal...

Fish Diversion in Hydropower Intake
Hydraulic model studies were conducted to develop a fish screening system to be used in the turbine intakes of Priest Rapids Development on the Columbia River, Washington. The system studied...

Water Supply Intake Structures on Western Rivers
Many of the problems experienced with water supply intake structures on western rivers result from a failure to mitigate the effects of moving sediments. Shallow but varying flow depths...

Vortices at Vertical Intakes
This paper presents the results of an experimental investigation designed to predict the formation of weak, free-surface vortices at vertical intakes with a headrace channel. A weak vortex...

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,...

Teaching Civil Engineering Using Spreadsheets
The use of microcomputers is becoming more and more prevalent in both large and small design offices as their cost continues to decrease, as their capabilities increase, and as more software...

Hydrodynamic Model of River Flow on a Microcomputer
This paper presents a one-dimensional, finite element model for simulating hydrodynamic responses to various conditions on a river system by using microcomputers. Based on the Saint-Venant...

Applications of Electronic Spreadsheets to Hydrologic and Hydraulic Computations
The application of electronic spreadsheets on micro-computers in solving routine hydrologic and hydraulic computations is suggested. In this paper, the Lotus 1-2-3 electronic spreadsheet...

Automation of a River Model
The U. S. Army Engineer Waterways Experiment Station (WES) has used physical models to study sedimentation problems since 1931. With the recent advent of new technology, it was realized...

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...

Embankment Overtopping Tests to Evaluate Damage
The paper reports on studies of embankments 6 ft high, 10 to 22 ft in crest width, and 3 ft in length, with slope varying from 2:1 to 4:1. Embankment surfaces include pavement, grass,...
