Summary
This webinar presents the results of two research projects conducted by the HC3 Laboratory group at ÉTS as part of Info-Crue. The projects are: Improved historical reconstruction of daily flows and annual maxima in gauged and ungauged basins and Development of a gridded observational dataset for the post-processing of simulations according to hydrological performance.
In the first case, multi-model weighting techniques were applied to a set of flow series from 144 HYDROTEL calibrations. The various calibrations were generated by modifying: (1) the HYDROTEL parameters, (2) the model input meteorological data sets, and (3) the evapotranspiration module used.
In the second case, precipitation and temperature grids were generated from a combination of station, reanalysis and satellite data. These grids cover all of Quebec and are available for the period from 1970 to 2019, at a spatial resolution of 0.1° and a temporal resolution of 24 hours.
