On the present platform "Hydro-CH2018: Scenarios until 2100" research results of the projects Hydro-CH2018 and CH2018 - prepared for applied hydrological questions - are offered. The platform was developed by the Hydrological Atlas of Switzerland (HADES) and is structured analogously to its "Data and Analysis Platform". Hydro-climatic and hydrological scenarios for the 21st century are presented. Currently included are precipitation and temperature scenarios, estimates of glacier development and the resulting runoff scenarios for selected catchments (maps L01 and L02) until 2100.
