This edition was the 40th anniversary of the ISH (International School for Hydraulics). The format of this conference highly encourages exchanges and discussions between participants, as it takes place in a hotel in the countryside. For this edition we were in Kąty Rybackie, Poland, by the Baltic Sea.

On the first day, the 22nd of May 2023, a few workshops were available, amongst others the Workshop on Ultrasonic Doppler by IBW-PAN and Ubertone in GDansk.

UB-Lab P measurements were then demonstrated on a small flume at our exhibition booth during the conference, allowing discussion about our three measurement techniques: UVP, ADVP and ABS. The UVP technology was perceived as a very good alternative to the ADV.

A field trip was organised to discover the Vistula Spit and the Institute of Hydro-Engineering (IBW-PAN) - Polish Academy of Sciences laboratory disposing amongst others of a big outdoor surface for physical models.

Thank you all for this very nice event!
