The Hydraulic Construction Platform (PL-LCH) is the result of a long tradition of hydraulic research. In 1926, Alfred Stucky was appointed Professor of Hydraulic Engineering, Waterfall Construction, Hydraulic Calculation and Foundations at the Engineering School of the University of Lausanne. In 1928, he founded the Hydraulic Testing Laboratory (LEH). In 1946, the school became the Ecole Polytechnique de l’Université de Lausanne (EPUL). In 1947, Daniel Bonnard was appointed Professor of Hydraulic Calculations, Geotechnics, Inland Navigation and Water Supply, and became Deputy Director of the laboratory. He was appointed Laboratory Director in 1958. In 1968, the Ecole Polytechnique de l’Université de Lausanne (EPUL) became the Ecole Polytechnique Fédérale de Lausanne (EPFL). In 1973, Walter Graf was appointed Professor of Hydraulics and Director of the laboratory, renamed Hydraulic Laboratory of the Ecole Polytechnique Fédérale de Lausanne (LHYDREP). In 1982, Richard Sinniger was appointed Professor and Director of the Chair of Hydraulic Engineering. The laboratory became the Laboratory of Hydraulic Constructions (LCH), and was later part of the Institute of Hydraulics and Energy, founded in 1988, together with the Hydraulic Research Laboratory and the Energy Systems Laboratory. In 1997, Anton Schleiss was appointed Professor and took over as Head of the Hydraulic Constructions Laboratory. In 2018, the laboratory became the Hydraulic Constructions Platform (PL-LCH) under the direction of Giovanni De Cesare as Operational Director. He was then joined in 2022 by Paolo Perona as Academic Director who was also promoted Adjunct Professor in 2023.
Alfred Stucky (1928-1958)
Prof. Dr. Alfred Stucky graduated from the Swiss Federal Institute of Technology of Zurich (EPFZ). Hired by Gruner in Basel in 1917, he perfected calculation methods and introduced the notion of elastic deformation of the arch dam for the construction of the Montsalvens dam. He also proposed to optimize the arch of the dam, no longer in the form of a circular arc, but as a parabola, by searching for the optimum shape, and not simply producing a drawing that could be used for calculations. In 1926, he was appointed Professor of Hydraulic Engineering, Waterfall Construction, Hydraulic Calculation and Foundations at the Engineering School of the University of Lausanne. In 1928, he founded the Hydraulic Testing Laboratory (LEH). In 1935, he founded the Geotechnical Laboratory. In 1940, he was appointed Director of the Ecole Polytechnique de l’Université de Lausanne (EPUL). During his career, he was involved in the construction of 38 dams between 1915 and his death in 1969, 20 of them in Switzerland. He contributed to 22 pre-projects, 29 detail studies, 26 construction projects and site supervision, and 12 expert reports , including those for Dixence and Grande-Dixence, Mauvoisin in 1951, Moiry in 1954, and Luzzone in 1958.
Daniel Bonnard (1958-1973)
Prof. Dr. Daniel Bonnard obtained a civil engineering diploma from the Ecole d’Ingénieur de Lausanne. After a brief spell with the Alfred Stucky office, he devoted most of his career to developing and then managing the Hydraulics and Geotechnics Laboratories. A lecturer from 1940, extraordinary professor from 1947 and ordinary professor from 1959, he retired in 1972. From 1938 to 1972, he was editor and then president of the Bulletin Technique de la Suisse Romande. In 1954, together with André Gardel, he founded the firm Bonnard & Gardel, Ingénieurs-conseils, which he chaired until 1977.
Walter H. Graf (1973-2001)
Prof. Dr. Walter H. Graf was appointed professor at the Ecole Polytechnique Fédérale de Lausanne (EPFL) in 1973, and Head of the Hydraulic Laboratory. Walter H. Graf has taught at the Universities of California-Berkeley, Cornell and Lehigh in the USA. In 1995 and 1999, he was appointed honorary guest professor at Tsinghua University in Beijing, China. In 1999, Walter H. Graf was awarded an honorary doctorate by the University of Graz (Austria) in recognition of his scientific work in the field of hydraulics. He has also been a visiting professor in South Africa (1974), Austria (1972, 1994), China (1984, 1994), Indonesia (1988), Italy (1990, 1993), Japan (1995), and the Soviet Union (1975, 1982, 1989), where he taught river hydraulics. In 1987, the XXII Congress of the IAHR was held in Lausanne under the direction of Walter H. Graf.
Richard O. Sinniger (1982-1997)
Prof. Richar O. Sinniger graduated in civil engineering from the Swiss Federal Institute of Technology in Zurich (EPFZ) in 1956. After three years at VAW, he worked as a construction management engineer in Switzerland, Canada and Greece. He subsequently took part in numerous hydraulic engineering projects worldwide. Appointed Professor at the Ecole Polytechnique Fédérale de Lausanne (EPFL) in 1973, he became Director of the Institute of Hydraulics and Energy in 1988.
Anton J. Schleiss (1997-2018)
Prof. Dr. Anton J. Schleiss graduated in Civil Engineering from the Swiss Federal Institute of Technology (ETH) in Zurich, Switzerland, in 1978. After joining the Laboratory of Hydraulic, Hydrology and Glaciology at ETH as a research associate and senior assistant, he obtained a Doctorate of Technical Sciences on the topic of pressure tunnel design in 1986. After that he worked for 11 years for Electrowatt Engineering Ltd. (now Pöyry) in Zurich and was involved in the design of many hydropower projects around the world as an expert on hydraulic engineering and underground waterways. Until 1996 he was Head of the Hydraulic Structures Section in the Hydropower Department at Electrowatt.
