In the July 2019 and October 2019 issues of the AHA Journal, I provided an overview of the Rising Bubble
Method (RBM) of streamflow measurement and outlined our progress with the development and
implementation of a practical RBM tool to improve the reliable measurement of water flowing in lowland
weedy streams. This is part of an MBIE Envirolink Tools project we are carrying out in collaboration with
several regional councils.
