Real-time monitoring of snowmelt infiltration in steep permafrost-affected rock slopes using fluorescent dyes
International audience Little is known about the connectivity between surface water and subsurface fractures in steep permafrostaffected rock slopes. Here we present a novel high-elevation field experiment designed to monitor real-time infiltration in rock fractures at Aiguille du Midi (3842 m a.s.l...
