Hydrotel, un modèle hydrologique distribué pouvant bénéficier des données fournies par la télédétection et les systèmes d'information géographique

Abstract: Les processus hydrologiques variant dans l'espace et dans le temps en fonction de la variabilité spatio-temporelle des entrées météorologiques et de l'occupation du sol ainsi que de la variabilité spatiale de la topographie et de la nature du terrain, un modèle conçu pour bénéficier des données provenant de la télédétection et des SIG a été développé. Les principaux objectifs poursuivis étaient: l'application au plus grand nombre de bassins possible, une sélection d'algorithmes permettant de tenir compte des d… Show more

“…The study resorts to the operational flow forecasting system put together by the Centre d'expertise hydrique du Québec (CEHQ) for public dam management (Turcotte et al, 2004), which relies on the hydrological model Hydrotel (Fortin et al, 1995). This system uses 3-h time steps to perform shortterm forecasts on small watersheds located upstream of dams with quick hydrological responses.…”

“…Hydrotel is a spatially distributed hydrological model with physical bases that performs independent simulations on relatively homogenous hydrological unit (RHHU), taking into account the spatial variability of topography, land use, soil type and meteorological variables within a basin (Fortin et al, 1995). A three-layer vertical water budget takes into account most of the macro-processes in action for infiltration and redistribution of soil-water within RHHU columns.…”

“…These regional values were established from the meteorological data in the database for the HYDROTEL model [56][57][58] applied to the Beaurivage watershed [59]. In this last application, precipitation and temperature were weighted means of the three stations nearest to the study site and the potential evapotranspiration was calculated with the equation developed at Hydro-Québec [57].…”
