Training Course on Stream gauging

The 4th IAHR-WMO-IAHS Training Course on Stream gauging is intended to be held as part of the RiverFlow 2018 conference, with separate registration.

Three days will be dedicated to Hydrometry basics, Field and classroom exercises and Recent advances (technology and uncertainty analysis), by internationally recognized lecturers (updated program as PDF file). The audience will be students and professional field hydrologists. The first three courses were held in Brescia (Italy, 2011), Andong (Korea, 2013) and Hanoi (Vietnam, 2014). The one-day seminar was held in Queenstown (New Zealand) in 2016.


The course venue is at Irstea building (room Rhône), exact address: 5 rue de la Doua 69100 Villeurbanne, France. This is not the same venue as that of the conference (Espace Tête d’Or).

Participants will have to register in two steps using the dedicated website:

1 – Application (before May 15th, 2018)

2 – Payment (before August 31st, 2018, using credit card only)

The number of participants is limited, therefore we cannot guarantee that all the applications (step 1) will be accepted. Note that before your application has been accepted, you are not registered yet.

Registration as participant to the course for the 3 days will include access to the lectures, transportation to the field site, use of measuring equipment, lunches and coffee breaks. Registration does not include accommodation and dinners. Registration for the third day only is possible.

In case of registration cancellation, no refund will be provided.

If you need that the invoice be addressed to a different name than the participant name, you must indicate it using the dedicated form (no change will be possible after that).


Full 3-day course:

  • Students: 50 €
  • Regular participants:  100 €

Third day only (Tuesday September, 4th):

  • 75 €
