Conferences - ECOHYDRAULICS

International Symposium on Ecohydraulics (ISE)

Launched in 1994, the International Symposia on Ecohydraulics aim to provide a platform for scientists and engineers worldwide to discuss cutting-edge scientific progress, compare and evaluate state-of-the-art technical methods, and recommend them to end users. The symposium typically runs from Sunday to Friday, with workshops and meetings on Sunday, sessions Monday through Friday, and a field trip on Wednesday. A complete list of past ISE conferences is provided on the IAHR website. Aspiring future Local Organizing Committees (LOCs) should keep an eye on the IAHR news stream. Calls for Letters of Intent from aspiring LOCs are typically announced 5-7 months before the next ISE.

ISE 2028 in Warsaw, Poland

The 17th International Symposium on Ecohydraulics will convene 25 June–1 July 2028 on the campus of the Warsaw University of Life Sciences (SGGW) in Warsaw, Poland. This event will mark the first ISE hosted in Central-Eastern Europe. It is organized jointly by SGGW, the National Inland Fisheries Research Institute, and the Institute of Geophysics of the Polish Academy of Sciences, under the theme Ecohydraulic Upscaling for Nature Restoration: advancing ecohydraulic methods from site-scale application to regional and continental strategy, in the light of EU Nature Restoration Law. The symposium is co-chaired by Piotr Parasiewicz (ORCID), originator of the MesoHABSIM mesohabitat simulation system, together with Tomasz Okruszko (SGGW) and Paweł Rowiński (IG PAS). Programme, sessions, and registration details are published at ise2028.sggw.edu.pl; enquiries go to ise2028@sggw.edu.pl.

ISE 2026 in Lausanne, Switzerland

The 16th International Symposium on Ecohydraulics convened 16-20 August 2026 at the SwissTech Convention Center on the EPFL campus in Lausanne, Switzerland, and closed a successful week: approximately 300 delegates took part in the first ISE held in Switzerland, and the first on European soil since Trondheim in 2014. The community thanks the Local Organizing Committee, led by Prof. Dr. Eng. Paolo Perona and Dr. sc. Giovanni De Cesare, for an excellently run symposium. The conference website is still alive at ise2026.epfl.ch.
