The regional climatic model ARW / WRF is used to make a dynamic downscaling of climate (driven by ERA-Interim) at a high spatial resolution (3 km2) over Burgundy, at daily time scale over the period 1980-2011. Climatic simulations were analyzed and compared with meteorological data, in order to validate them with the aim of their use by hydro(geo)logic models. The hydro-climatic parameters necessary as climatic inputs of these models, in particular precipitation and evapotranspiration, reproduce correctly the spatial and temporal variability (in spite of an overestimation of simulated precipitation), which allows their use in a hydro-climatic modelling chain. Keywords: climate change, water resource, regional climate modelling, hydrologic modelling, Burgundy.mation of simulated precipitation), which allows their use in a hydro-climatic modelling chain.
