Emmanuel MOUCHE

Biography

Emmanuel Mouche received a Master degree and a Ph.D, both in Solid State Physics, and an Accreditation to Supervise Research (HDR) in Geosciences, in 1981, 1985 and 2011 respectively, all from the University of Paris XI, Faculté d’Orsay, now University Paris-Saclay. He joined in 1985 the French Atomic Energy Commission (CEA). He worked at the Nuclear Energy Division on the modeling of high level waste repositories, first as an Engineer, then at the head of a laboratory that he created in 1998. In 2002 he joined the Climate and Environment Sciences Laboratory at the Fundamental Research Division where he supervises currently the hydrologic modeling team. His research activity concerns the physical, mathematical and numerical modeling in geosciences, principally in environmental fluid mechanics. Since 2015 he is Senior Scientist at the CEA.

Research interests

Hydrologic modeling, flow and transport in porous media, heterogeneous media, upscaling, inverse modeling, stochastic and statistical approaches, numerical methods, process couplings.

My current research focuses on:

• Upscaling hydrologic models for land surface and climate models.
• Surface subsurface coupling with integrated distributed numerical models.
• Overland flow generation and erosion at different scales. Collaboration with IRD (Institute for Research and Development) in South East Asia.
• Surface and subsurface flows connectivity. Link with collective processes and critical phenomena theory in statistical physics.
• CO₂ sequestration reservoirs. Upscaling buoyant migration of CO₂ in a heterogeneous reservoir.
