QUALITY OF WATER BRANCH TECHNICAL MEMORANDUM NO. 79.19

Subject:  PROGRAMS AND PLANS New WATSTORE parameter codes

This is to inform you of two new WATSTORE parameter codes:

Code                           Description

81903               Depth at sample location, total (feet)

81904               Stream velocity, point (feet per second)

These codes were requested specifically so that point-integrated 
sediment data may be stored and retrieved for publication in a 
more informative format. Of course, they may also be used to 
reference sampling locations and conditions of other types of data 
besides sediment. Several districts are conducting special 
sediment studies for the Army Corps of Engineers which include 
measurement of velocity and collection of sediment samples at 
several points in the vertical.

With the addition of these codes, complete description of the 
location of each sampling point relative to the channel bed and 
banks will be possible. Other available parameter codes that 
relate to sampling location are:

   Code                            Description

00001 or 00009         Cross-section location (feet from left or
                        right bank)

  00003                Depth of collection (feet from surface)

  00004                Stream width (feet)

Districts should review data stored under parameter code 00055, 
stream velocity, mean (feet per second), and transfer any point
velocity data to the new parameter code 81904.
