# Investigation of Rain-On-Snow Floods under Climate Change
## 4 Conclusions  
Climate change can lead to changes in the characteristics of ROS floods in the future in many parts of the world. In this regard, we investigated the possible changes in seasonality, magnitude, and frequency of ROS floods in the future for the two selected catchments located in different climate regions in Slovenia. The CemaNeige GR6J lumped conceptual model was applied for the simulation of ROS floods in combination with the results of five GCM/RCM models for the RCP4.5 climate scenario. Based on the presented results the following conclusions can be made:  
* For catchments located at higher elevations (i.e., Soca) with mountain climate characteristics, the strength of seasonality of ROS events could decrease in the future (i.e., based on the median result of five GCM/RCM models). This means that ROS floods may occur more frequently in the periods of the year in which in the past we only had few events.
* A shift (i.e., one or two weeks) in the time of occurrence (MD) of ROS floods could be expected for both investigated catchments in the future (i.e., based on the median result of five GCM/RCM models).
* In general, more ROS floods can be expected in the future. Moreover, the magnitudes of the most severe ROS floods could increase. However, median values indicate a slight decrease in ROS-flood magnitudes, which could be attributed to the fact that the number of small magnitude ROS floods would also increase.
* Results indicate a high variability among the five investigated GCM/RCM models, which could be related to the high uncertainty. Therefore, additional investigation into ROS-flood characteristics in the future is needed to validate the aforementioned conclusions. This means that more studies should be conducted in similar environments. Along with the changes in the meteorological conditions, which are incorporated in the GCM/RCM models, one could also expect other changes in the future, such as land-use changes, which also have an effect on the elements of the water cycle that are related to the ROS-mechanism generation.
