Experimental Study of the Cross-Flow-Turbine
The performance of the Cross-Flow or Banki Turbine (C-F-T) was studied experimentally by varying the number of blades, the runner diameter, and the nozzle entry arc under flow/head variations....

Report of the Task Committee on Test Cases for Verification of 2-D Depth-Averaged Hydrodynamic Models
The Computational Hydraulics Committee has established a Task Committee to identify test cases which can form a uniform, objective basis for model verification. The scope is limited to...

Portland's New Water Pumping and Hydropower Station
The City of Portland, Oregon, recently placed into service a 100 mgd pumping station as a major milestone in developing a backup and emergency groundwater supply. The facility is also...

Frazil Ice Control Using Air Guns
The design of the J. H. Campbell, Unit 3, Cooling Water Intake in the late 1970's used some new ideas and concepts in response to a strong concern for fish protection at a...

Laboratory Studies for the J. H. Campbell, Unit No. 3, Cooling Water Intake Design
A three-year study sponsored by the Empire State Electric Energy Research Corporation was conducted to determine the overall efficiency of a full-scale angled screen demonstration facility...

The Role of Hydraulics and Sediment in Large River Ecology
The National Science Foundation has sponsored a project under the long term ecological research (LTER) program which is called the 'Illinois Rivers' LTER project....

Yakima Remote Control System: Supervisory Control and Data Acquisition
The Yakima Remote Control System is a computerized supervisory control and data acquisition (SCADA) system developed for the operation of the Bureau of Reclamation's Yakima Project in...

Response of Floating Structures in a Directional Sea
A finite element numerical model is presented to predict the behavior of long floating structures in a multi-directional sea. A follow up numerical model analyzes an important but mostly...

Explicit Hydraulic Modeling of Sedimentation Transients in Alluvial Channels
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,...
