On 23-26.05.2023 the XL edition of the School of Hydraulics was held, this time in the form of an international conference (International School of Hydraulics 2023). The event was organised by the Institute of Hydro-Engineering of the Polish Academy of Sciences and the Institute of Geophysics of the Polish Academy of Sciences.

The School of Hydraulics has a long tradition dating back to 1981. Over the years, the event has been held regularly, with the exception of 2020 and 2021, when the organisation of meetings was suspended due to the epidemiological situation. For the first 25 years, the School was organised by the Institute of Hydro-Engineering of the Polish Academy of Sciences, under the supervision of its founding father, Prof. Dr. Wojciech Majewski. In 2003 it was decided to internationalise the school by organising an international school every two years. Since then, the National School of Hydraulics has been run by the Hugo Kołłątaj Agricultural University in Cracow, and the International School of Hydraulics by the Institute of Geophysics of the Polish Academy of Sciences.

The school is under the umbrella of the Water Management Committee of the Polish Academy of Sciences and the International Association for Water Research and Engineering.

The Jubilee School was attended by 5 lecturers and 75 participants.

As every year, we thank all the guests, organisers and participants for this wonderful and creative time. It was an unforgettable time full of knowledge, inspiring talks and sharing of experiences. We are happy to have been part of this important international conference. We look forward to the next edition of the Hydraulics School!
