    The river discharge is an important component of the in Earth’s water cycles which couples the continents and oceans in the climate system. These fluxes are difficult to estimate due to un-gauged rivers, submarine groundwater discharges, human activities, and measurement errors. One approach is based on the observed river discharge and a simple annual water balance model for ungauged rivers, but it only provides flux estimates with large uncertainties and low temporal frequency which are unsatisfactory for oceanic modelling needs.

    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.

    Pour fournir des simulations fiables, les modèles hydrologiques nécessitent généralement le calage de leurs paramètres sur des observations de débit. Toutefois, ces dernières sont limitées faisant de la plupart des bassins versants des bassins dits non jaugés. Des méthodes alternatives, appelées régionalisations, sont alors nécessaires pour estimer les paramètres des modèles.
