The 3rd IAHR-WMO-IAHS Training Course on Streamgauging is organised by the IAHR Working Group on Applied Hydrology and the Committee on Experimental Methods and Instrumentation, WMO, IAHS and Thuyloi University.

This community provides the latest version of the training material on stream gauging in English, Spanish French and Russian. It is only available for instructors who can download and use it to prepare courses. A discussion forum is also available.

The course aims at providing a primer to the new edition of the WMO Manual of Stream Gauging, published in 2010, by describing both conventional methods as well as recent technological advancements in stream gauging (with special emphasis on recent advances in
the hydroacoustic and image-based instruments).

The last twenty-five years have seen great advances in the instrumentation available for hydrometry and in the procedures and methods for the measurement of discharge. Due to several reasons, this progress has not seen a parallel development of guidance material and standards.

At its Twelfth Session (Geneva, October 2004), the Commission for Hydrology of WMO, having reached a general consensus that information on the appropriate use of this instrumentation and methodologies is direly needed, identified under the priority thematic area "Basic systems (hydrometry and hydraulics)" an activity to develop a proposal and implement a project to assess the performance of flow measurement instruments and techniques against WMO standards.
