Changes in hydrological regime in High Arctic non-glaciated catchment in 1979–2020 using a multimodel approach
Assessing hydrological consequences of climate change at the catchment scale is recently among key problems in hydrology. This study focuses on the estimation of changes in the hydrological regime in the Fuglebekken catchment in SW Spitsbergen (Svalbard). For this purpose, 50 rainfall-runoff models...

Assessing hydrological consequences of climate change at the catchment scale is recently among key problems in hydrology. This study focuses on the estimation of changes in the hydrological regime in the Fuglebekken catchment in SW Spitsbergen (Svalbard). For this purpose, 50 rainfall-runoff models were calibrated using available hydrometeorological observations. The models were validated based on archival flow and SWE observations, and proxy data from time-lapse cameras. Six models (FLEX-IS, GSM-SOCONT, PRMS, HBV, Nordic HBV, and GR4J) with the best performance were applied to reconstruct the past hydrological conditions and analyse the trends in flow regime in the period 1979–2020. Statistically significant changes at 0.05 level in the flow regime indicators were detected, including the number of days with the active flow during the calendar year (10.8 d per decade), during the mid-May‒November period (9.8 d per decade), the date of the first day with the flow (−4.7 d per decade), and the last day with the flow during mid-May‒November (8.4 d per decade).
