      abstract     = {Studying snow is crucial as it impacts the hydrological
                      cycle as well as the albedo, thereby theradiation budget.
                      Therefore, changes in snow patterns can affect water
                      availability, river flowpatterns, and overall catchment
                      water balance. This thesis aims to investigate trends
                      insnowpack variables and their potential impacts on
                      hydrological processes for snow-dominatedand
                      snow-rain-dominated regions in Europe. To identify trends in
                      snowpack variables, Europeanwatersheds are classified into
                      snow and snow-rain-dominated based on the snowfall
                      fractionfrom the E-OBS meteorological data and a temperature
                      and precipitation threshold. For thesewatersheds, snowfall
                      (SF), and rainfall (RF) from in-situ meteorological data,
                      snow coverduration (SCD) from MODIS satellite, and snow
                      water equivalent (SWE) from ESA GLOBSNOWand GLWS2.0 products
                      are analyzed to find trends and patterns during 2000-2022.
                      Additionally,river discharge data at 862 Global Runoff Data
                      Center (GRDC) stations were also compiled toinvestigate the
                      impact of snow trends on changes in river flow and center of
                      timing (CT). Resultsshow increasing trends in SF, SWE, and
                      discharge and decreasing trends in SCD insnow-dominated
                      watersheds. Seasonally, the trends in both snowpack
                      variables and rainfall aremore pronounced in the winter than
                      spring season. In addition, the increasing trends in
                      meandischarge show a strong positive correlation with
                      increasing SWE, particularly in thesnow-dominated
                      watersheds. However, the trends in CT indicate shifts of 2-3
                      days across manystations, suggesting an accelerated melting
                      of snow attributed to rising temperatures. Thesetrends align
                      with the concurrent decreasing trend in SCD. Furthermore,
                      water availability isassessed by comparing the change in
                      snowpack and streamflow anomalies with total waterstorage
                      (TWS) from GRACE satellites. Overall, the TWS shows a
                      decreasing trend in the snowand snow-rain-dominated
                      watersheds which we suggest is due to rapid snowmelt at
                      hightemperatures despite high SF and SWE. These results
                      highlight the important changes incryosphere–hydrological
                      processes in the recent past, providing valuable information
                      forintegrated water resource management in Europe.},
