Mapping 2-D and 3-D Velocity Components in Circular Conduits Using an Electromagnetic Current Meter and a 5-Hole Pilot Probe
The techniques presented in this paper facilitate the visualization of the two-dimensional and three-dimensional flow fields at arbitrary sections in a conduit. They have been used to...

Velocity and Turbulence Measurement from the Illinois and Mississippi Rivers
This paper presents a data measurement program that was used for collecting the velocity data associated with barge-tow traffic on the Illinois and Mississippi Rivers and includes a discussion...

Velocity Measurements by the One-Orange Method
Application of the most sophisticated instrumentation - so called state-of-the-art equipment - is not always necessary nor even desirable for measurement of mean velocities in verticals,...

Sediment Measurement Instrumentation A Personal Perspective
The development of the suspended sediment samplers in the 1940s was a major contribution to the science of sedimentation and provided for the proper development of dams, reservoirs, and...

Low-Cost Bridge Scour Measurements
This paper reports on the use of a low-cost, highly portable sonar system. The ease of use of the instrument and the short time required to make measurements should make this system valuable...

Developing Air Concentration and Velocity Probes for Measuring Highly-Aerated, High-Velocity Flow
The U.S. Bureau of Reclamation's stepped spillway overtopping protection research program required velocity and air concentration profile data be obtained during testing in a large, 15.2-m-high...

Application of a Needle Probe in Measuring Local Parameters in Air-Water Flow
In this paper, development of a double needle probe for measuring local parameters in air-water mixtures is explained. This probe is designed to measure flow velocities up to 10 m/s and...

Acoustic-Doppler Velocimeter (ADV) for Laboratory Use
A remote-sensing, three-dimensional (3D) velocity sensor has been developed and tested for use in physical model facilities. The sensor is based on the Acoustic Doppler principle and measures...

Observations on the Growth of an Internal Boundary Layer with a Lidar Technique
The distribution of atmospheric water vapor across a step change in surface humidity (dry-wet) was observed by a Lidar measurement technique under neutral atmospheric stability condition....

Instrumentation Needs and Possibilities: A Dialogue Between Suppliers and Users
The present symposium includes a panel discussion to address and illuminate needs and possibilities in hydraulic instrumentation. The panel discussion is organized with the intent of promoting...

Bridge Scour Instrumentation
This paper presents a brief status report of research funded by the National Cooperative Highway Research Program (NCHRP Project 21-3, Instrumentation for Measuring Scour at Bridge Piers...

Analysis of Selected Prototype Wave and Runup Data
An investigation of wave runup using video camera technology at Duck, N.C. is discussed. Results are provided from a subset of the runup experiment and wave runup level probability density...

Air Entrainment and Bubble Behavior in Plunge Pools
This study analyzes air entrainment by falling nappes and bubble behavior in plunge pools, using an experimental-analytical-numerical method. The experimental work was done at the Tennessee...
