Subject:  National Coordination and Support for Acoustic Doppler Current
          Profiler Activities

The purpose of this memorandum is to announce that Kevin Oberg of the 
Illinois District will serve as national coordinator of the Acoustic 
Doppler Current Profiler (ADCP) activities for the Office of Surface 
Water (OSW). Kevin will also serve as the initial point of contact for 
ADCP support issues. Kevin's ADCP experience includes the measurement of 
low velocities resulting from leakage through control structures, record 
high flows on the Mississippi River in 1993, and velocity and streamflow 
on the Colorado River. He has organized and taught three training classes 
on the use of ADCP's for streamflow measurements. 

Kevin's responsibilities for the coming year will include the following 

*  Organize and coordinate ADCP training classes and workshops,
*  Assist users with ADCP related questions and problems,
*  Assist District offices with developing new ADCP applications and
*  Develop independent ADCP testing and quality assurance procedures,
*  Test and evaluate ADCP software,
*  Evaluate new velocity extrapolation techniques, and
*  Represent the USGS in ADCP activities involving other agencies.

Kevin has set up a listserv for exchanging information on ADCP's via 
email. To subscribe to the listserv, send an email to with the words 'subscribe' and 
'end' on separate lines as the body of the message. Email can be sent to 
everyone on the list by sending email to

The coordination and support for ADCP activities is part of OSW's 
continued support of new technology for District programs. For several 
years, OSW has sponsored an ADCP work group to provide operational 
guidance to users. The work group, including representatives from 
Environment Canada and the U.S. Army Corps of Engineers (USACE), has put 
on three ADCP training classes--two in the United States and one in 
Canada. They have planned and commissioned the preparation of three 
reports: a quality-assurance plan, an operational manual, and a report on 
a verification study.  The quality-assurance plan has been published as 
Open-File Report 95-701, "Quality Assurance Plan for Discharge 
Measurements Using Broadband Acoustic Doppler Current Profilers," 
by Stephen W. Lipscomb. The verification study, comparing ADCP-produced
discharges with stable-rating discharges at 12 gaging stations, has been 
published as Water Resources Investigation Report 95-4218, "Evaluation of 
Acoustic Doppler Current Profiler Measurements of River Discharge," by 
Scott E. Morlock. The operational manual is in draft form and will be 
available shortly.  The current members of the ADCP work group are:

W. Scott Gain       Florida District
Stephen Lipscomb    Idaho District 
Scott Morlock       Indiana District
David Mueller       Kentucky District
Kevin Oberg         OSW            
Thad Pratt          USACE     
Mike Simpson        California District
Phil Zrymiak        Environment Canada

Please feel free to contact Kevin or anyone in the OSW for information or 
assistance in matters related to ADCP's.
