The objective of the proposed project is to evaluate and predict the relationship between winter snowpack and summer low flows in three mountainous streams in central Switzerland (northern Prealps), northern Czech Republic (Jizera Mountains) and central Georgia (Little Caucasus). As this relationship has been commonly assessed by statistical approaches, little is known about the role of dominant processes snowmelt, groundwater recharge and evapotranspiration in the generation of summer and autumn low flows in mountainous streams across Europe. This proposal focuses first on the parallel application of the distributed hydrological rainfall-runoff models PREVAH and GSSHA in three nested mountainous catchments to simulate and predict the runoff response in different geographical settings. Second, the runoff generation from snow accumulation, snowmelt and groundwater recharge in the three streams will be investigated using environmental isotope methods. Third, the relations between anomalies in air temperature, aridity index, potential evapotranspiration and the runoff generation processes will be parameterized to allow for better simulation of low flows and mitigation of hydrological droughts. This approach builds on the recent Swiss applications of the model PREVAH and Czech applications of the model GSSHA and has a substantial innovative potential to be further developed through international cooperation, experimental work and parameterization of the models in different geographical settings. The modelling with PREVAH of all study areas will be conducted by the Swiss team and the modelling with GSSHA will be conducted by the Czech team. The experimental work on environmental isotopes will be conducted in parallel in all partner countries primarily using the laboratory facilities in the Czech Republic, supported by facilities in Switzerland and Georgia. The principal expected output of the project is an improved version of the model PREVAH that includes a better understanding of the role of snow in the generation of low flows and therefore allows for a better prediction of hydrological droughts in mountainous catchments. The application of the modelling approaches in different mountainous zones from the Prealps to the Little Caucasus will expand the understanding of how summer low flows and droughts are driven and how they can be mitigated.
