Sebastien Erpicum is Assistant Professor at the Laboratory of Engineering Hydraulics - HECE, University of Liege. He graduated in Civil Engineering at the University of Liege (ULg), Belgium, in 2000. After joining the HACH research unit at the ULg as a research engineer, he obtained his PhD on the subject of free surface turbulent flow numerical modelling with multiblock grids in 2006. He then worked as a senior researcher, involved in many combined numerical / physical studies of dams and hydropower plants all over the world, and spent 6 months at the IWW-RWTH in Germany. Since 2010, he is in charge of the Laboratory of Engineering Hydraulics in the new research group on Hydraulics in Environmental and Civil Engineering - HECE of the ULg and has been appointed as Assistant Professor in 2015. His field of activities covered the complementary domains of education, research and services in applied hydraulics, considering both numerical and physical modelling approaches.

Frédéric Laugier is head of the Structural Branch of the Technical Direction at Electricité de France - Hydro Engineering Center, EDF-CIH. He graduated in Civil Engineering from the Ecole Nationale of the Ponts and Chaussées (ENPC) in Paris (France) in 1996. His final year was spent at Imperial College, London, through the Erasmus exchange programme. He joined the EDF Hydro Engineering Centre in 1998. As a design engineer and project leader he has taken part in various civil engineering and hydro engineering projects, including the rehabilitation and maintenance of existing EDF dams. He was the Project Leader of the design and construction of the first two PK Weirs built on the Goulours and Saint-Marc dams in France. From 2008 to early 2011 he also was General Secretary of the French Committee of Large Dams. He is currently head of structural branch of technical direction of EDF Hydro Engineering Center.

Michel Ho Ta Khanh is an independent expert, retired from Electricité de France. He graduated in Civil Engineering from the Ecole Nationale des Ponts and Chaussées (ENPC) in Paris (France) in 1966. He has 35 years of experience in the fields of design and construction of hydropower structures, in particular concerning dams and the associated hydraulic structures (bottom outlets, spillways, tunnels). He has participated in the studies and construction of nearly 80 projects, both in France and abroad, and particularly in Africa and Asia. He was the "Secrétaire du Comité de l'Hydraulique d'EDF" in charge of the review of all the main EDF dam projects. He is at present an independent expert in France, Morocco and Vietnam. He has participated in particular during these last 12 years to the study and design of the Vietnamese P.K weirs. He is member of the CFBR, VNCOLD and two Technical Committees of ICOLD.

Prof. Dr. Michael Pfister works at the Haute école d'ingénierie et d'architecture HEIA-FR. He graduated in Civil Engineering from ETH Zurich, Switzerland, in 2002. He then joined the Laboratory of Hydraulics, Hydrology and Glaciology (VAW) of ETH Zurich as a Research Assistant, and obtained a Doctorate in Sciences in 2007. In 2010 he joined the Laboratory of Hydraulic Constructions (LCH) of EPFL, as a Research and Teaching Associate. In 2016 he was appointed Full Professor for Hydraulic Engineering at Haute école d'ingénierie et d'architecture Fribourg (HEIA-FR). His activity mainly focuses on research related to wastewater hydraulics, spillway hydraulics and high-speed two-phase air-water flows. Further, he is active as an expert in practice and related to physical model studies. He is a member of the Leadership Team of the IAHR Hydraulic Structures Committee, and of several national commissions.
