Interactive comment on “ Future runoff regime changes and their time of emergence for 93 catchments in Switzerland ” by Regula Muelchi et

Muelchi et al. describe the modelled effect of climate change on river regimes. For that they analyse runoff changes, regime changes and time of emergence of changes for three different climate scenarios. The motivation and novelty of the study are the use of newly released climate scenarios and hydrological model simulations that take changing aspects of climate change (for example glaciated area) into account. They supply detailed results on what changes in runoff are to be expected for Switzerland under the different scenarios. This is a great contribution and will be especially useful for water resources planning. For that the split of the analysis for the different seasons will be useful as well. Additionally, Muelchi et al calculate the time of emergence, which indicates that high elevation catchments will show climate change impact earlier than
