High capacity tensiometers (HCT) allow the direct measurement of soil matric suction, and their major limitation is the occurrence of cavitation.In this paper HCT designs using different ceramic filters with varied air entry values (AEV), varied reservoir sizes, and different pressure transducers are assessed as to determine the impact that each co
As an icon of anthropogenic climate change, alpine glaciers are highly sensitive to climate change.However, there remain research gaps regarding trends in climate extremes in glacierized regions and their relationship with local glacier mass balance.In this study, these relationships and their underlying links were explored in a typical glacierized
