    Masaki Hayashi, Ph.D., is a professor in the Department of Geoscience at the University of Calgary. He holds the Canada Research Chair in Physical Hydrology. Hayashi received his B.S. and M.S. in earth sciences from Waseda University and Chiba University, respectively, in Japan, and his Ph.D. in earth sciences from the University of Waterloo in Canada. His main research interests are in the connection among groundwater, surface water, and atmospheric moisture in various environments ranging from the prairies to the mountains.

    David Boutt2018 Birdsall-Dreiss Distinguished Lecturer

    David Boutt is an Associate Professor in the Department of Geosciences at the University of Massachusetts-Amherst.  He received B.S. and M.S. degrees from the Department of Geological Sciences at Michigan State University in 1997 and 1999.  His MS work focused on understanding the impacts of land-use change on groundwater quantity and quality at the watershed-scale.  He earned his Ph.D. from the New Mexico Institute of Mining and Technology (Socorro, New Mexico, USA) in 2004 and held a postdoctoral position at Sandia National Laboratories before joining the faculty at UMass-Amherst in 2005. During his Ph.D. research he was awarded an AGU Horton Research Grant.  Dr. Boutt’s dissertation work focused on the coupling of fluid flow and deformation in fractured and faulted media through the development of discretely-coupled fluid-solid models. His current research program focuses on understanding the role of groundwater in catchment-scale hydrologic processes.

    Depuis plus de 10 ans, la géophysique est un outil privilégié à Montpellier pour étudier les aquifères karstiques, complexes et hétérogènes. Depuis la construction de l’observatoire du Larzac en 2011, un gravimètre supraconducteur mesure en continu et avec une grande précision les changements de la pesanteur, et donc de la masse d’eau souterraine. En plus de permettre des bilans hydrologiques précis, on peut en obtenir de nombreuses informations utiles comme les types de transferts à l’œuvre ou le débit souterrain.

    Statistics are often used to perform data reduction: that is, summarizing a large amount of information into a model containing a limited number of parameters. In geoscience, there is often a need to do the opposite as data reduction: based on limited information about a studied process, one wants to stochastically generate more data, which ideally should be statistically indistinguishable from the truth.
