Part 10: Application of Point Acoustic Doppler Velocity Meters for Determining Discharge in Open Channels WISBF GL 100.10–2013

Water Information Standards Business Forum - Bureau of Meteorology , 02 August, 2013

Purpose

The purpose of this document is to provide guidelines for recommended practice to ensure that the collected measured streamflow data are:

  1. accurate;
  2. defendable; and
  3. consistent across water monitoring organisations operating under these guidelines.

This is the minimum guideline that shall be followed to allow the collected data to withstand independent validation and data integrity checks. Additional field procedures may vary between organisations and States.

Scope

This document deals with the use of point acoustic Doppler velocity meters (PVMs) for determining streamflow in open channels. It specifies the required procedures and methods for collecting data by Australian operators. It specifies procedures for the collection and processing of surface water velocity data collected by PVMs.

The document does not include or rewrite instrument manufacturers’ operating instructions for their individual instruments. Nor does it detail Standard Operating Procedure’s (SOPs) of organisations using these instruments. However, it is expected that those SOPs are sufficiently robust to withstand independent scrutiny.

This document specifies requirements for the use of point velocity type acoustic Doppler velocity meters, training of operators and the treatment of uncertainty of measurements.
