Environmental Hydraulics Laboratory LHE
History of LHE
The creation in 1928
The Environmental Hydraulics Laboratory is the heir to a long tradition of research in hydraulics. Hydraulic Research began in Lausanne in the mid 1920s in the development of "houille blanche" (hydropower). In 1928, Alfred Stucky created Hydraulic Testing Laboratory. He was joined in 1947 by Daniel Bonnard, who became the director of the laboratory in 1958. In 1968, the Polytechnic School of the University of Lausanne (EPUL) became the Ecole Polytechnique Federale de Lausanne. In 1973, Professor Walter Graf is named hydraulic EPFL professor .

The split in 1982
In 1978, the hydraulics laboratory became LHYDREP. Then in 1982, it is divided into two parts:
- A section is devoted to water constructions projects : it is the Hydraulic Constructions Laboratory (LCH) under the direction of prof. Richard Sinniger (1982-1998), and then prof. Anton Schleiss.
- The other component is oriented general hydraulics. Originally called Hydraulic Research Laboratory, it became the Environmental Hydraulics Laboratory in 2003, marking the turn toward environmental problems, mainly water management and natural hazards. The unit was led by prof. Walter Graf (1982-2001), Dr Mustapha Altinakar (2002) [now a research professor at the University of Mississippi], Dr Ulrich Lemmin (2003) [retired in 2007], and is currently headed by prof. Christophe Ancey.
The revival in 2003
Since late 2003, the team of Prof. Christophe Ancey turned his attention to the various forms of transport of materials in water (in its different states) with the rheological point of view. Many generators flows risks to human activities are induced by the flow of water : floods on safe watercourse, but also debris flows (highly concentrated sediment transport form) and avalanches. As an application of this research should we mention the development of tools for risk management and planning : risk zoning, design of protective structures, evaluation of long-term behavior of watersheds and rivers.
