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,...

Simulation of Evaporation Ponds for Liquid Waste Disposal
A computer model for designing and simulation of evaporation ponds is developed. It is based on the principle of mass conservation for water, for the total dissolved solids (TDS), and...

Aquifer Management Using Discrete Kernels in Microcomputers
An interactive simulation model based on the 'Discrete Kernel Approach' (a Green's function approach) is presented. The response functions (or the...

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...

A Hydrologic Model Developed for Microcomputers
An event oriented hydrologic catchment model has been programmed for use on a microcomputer. Because the program is written in PASCAL, it uses features of this language that eliminate...

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,...

Overtopping of Small Dams?An Alternative for Dam Safety
A research effort was initiated in 1983 by the Bureau of Reclamation to gain insight in the development of cost-effective modifications to small embankment dams which would enable them...

Embankment Overtopping
Embankment overtopping and dam safety are major concerns of civil engineering and the general public. Very little is known about overtopping events and much less has been published or...

3-D Orthogonal Curvilinear Circulation Modelling
A three-dimensional circulation model has been developed using an orthogonal curvilinear coordinate system. The model as constructed is capable of simulations on a variety of time and...

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...

Applications of Discrete-Element Computational Models to Transient, Multi-Dimensional Problems in Hydrology
