International Symposium on Ecohydraulics News


ISE2022 has been highly impacted by the pandemic. The original local organizing committee (LOC) in Lisbon withdrew from hosting the event because they were under a lot of distress. The Ecohydraulics leadership team was able to establish a new LOC in a different location. ISE2022 will now be held in Nanjing, China hosted by Hohai University, Yangtze Institute, and Nanjing Hydraulic Research Institute. We greatly appreciate how the new LOC has stepped up to take on this effort with short notice. They are proceeding with the steps to get the event going. more news will follow as it develops.


The Ecohydraulics leadership team has selected the LOC for ISE2024. It is co-led by Prof. André St-Hilaire and Dr. Valerie Ouellet. ISE2024 will be held in Quebec City, Canada. In 2024 it will have been 25 years since an ISE was held in North America. This is the longest time that the conference has been away from a continent (not counting Antarctica). In 1999 ISE was held in Salt Lake City, USA. Before that, in 1996 it was held held in Quebec City. Therefore, this marks the second time that ISE has returned to a past hosting city, as the 1994 and 2014 events were held in Trondheim.


It is never too soon to start thinking about your interest in hosting an ISE conference. Geographic location is a major factor considered in choosing an ISE LOC, but not the only factor or always decisive. Still, there has not been an in-person ISE in Africa since 2002, South America since 2009, or Europe since 2014. if you are located in one of these regions, please consider thinking about developing an LOC team and letter of interest to be vetted in 2022.

Takashi Asaeda has taken leadership of the Journal of Ecohydraulics as of January 2021. There will be a period of strategic planning and then I expect we’ll see some new developments, so keep your eye on the journal.

The IAHR Ecohydraulics Technical Committee leadership team has now held three quarterly meetings since it was empaneled in June 2020. meetings were held in August and October 2020 as well as February 2021. Minutes of those meetings are available from IAHR. To receive those, you can join our technical committee for free, just by contacting IAHR staff and making the request.

As part of ISE2020, there was an open discussion forum for the Ecohydraulics community. For the first ~30 minutes the community was updated on many issues, and then for the remaining time the audience raised questions and had discussion. Thank you to those who participated.
