|Turbidity-Meter Manufacturers and Others Sought for Sediment Group
Subcommittee D19.07 on Sediment, Geomorphology and Open Channel
Flow seeks participation for a new task group developing a Standard
Guide for Continuous Monitoring of Suspended-Sediment Concentration
in Open Channel Flow Using Optical Instrumentation. The task
group will operate in Committee D19 on Water.
Manufacturers of optical equipment such as turbidity meters, and
individuals experienced in this type of data collection are invited
to join this activity.
The proposed guide will cover:
Equipment and basic procedures for installation, operation,
and calibration of optical equipment to determine the continuous
or near-continuous concentration of suspended sediment in open
Nephelometers and backscatter-type meters to record data that
can be correlated with mean cross-sectional suspended-sediment
General principles will be emphasized; step-by-step instructions
will be given in a few instances. ASTM membership is not required
for this activity.
To participate or comment, contact Douglas G. Glysson, U.S. Geological Survey, Reston, Va. (phone: 703/648-5019). Committee
D19 on Water meets Jan. 20-24 in Cocoa Beach, Fla. For meeting
