. En, ensemble de la période couverte par cette étude : 1987- 2010, nous disposions de seulement quatre stations météorologiques et de débits. Ainsi, toute la problématique de ce travail était d'étudier la dynamique d'enneigement de 1987 à, avec très peu de mesures météorologiques (et hydrologiques) pour confirmer les observations et sans aucune mesure de neige « in situ, 2010.
