Comparison of threshold hydrologic response across northern catchments
Abstract Nine mid‐latitude to high‐latitude headwater catchments – part of the Northern Watershed Ecosystem Response to Climate Change (North‐Watch) programme – were used to analyze threshold response to rainfall and snowmelt‐driven events and link the different responses to the catchment characteri...
