Survey on karstic hydrology of western alps, karstic systems and springs regimes. In this paper, we have tried to bring out a typology karstic hydrological systems, according to the degree of karst organisation and the feeding conditions. Afterward the hydrological efficiency of these systems and the springs regime are specified taking in account the available data (boards I and II). At last it's interesting to compare hydrological and hydrochemical cycles in the different sorts of karsts.Dans cette note, nous avons essayé de dégager une typologie des systèmes hydrologiques karstiques, en fonction du degré d'organisation des karsts et des conditions d'alimentation. Compte-tenu des données disponibles (tableaux l et II) on précise ensuite l...
