Abstract This study investigates the temporal processes of suprapermafrost groundwater (SPG)‐supplied streamflow in alpine permafrost regions, aiming to fill gap understanding this process from a water‐age perspective. Precipitation, streamflow, and SPG samples were collected Three‐Rivers Headwaters Region (TRHR). We defined physical meaning F yw (the young water fraction) calculated it for first time. The results showed that TRHR, mean travel time (MTT) was 159 days, approximately 46.4% younger than 77 whereas MTT 342 12.2% 97 days. correlation analysis revealed various climatic factors played dominant roles recharge variations SPG‐supplied within TRHR. rate did not significantly affect ; however, thickness active layer ultimately controlled transit distribution. Regression further demonstrated nonlinear impact precipitation, average temperature, freezing days on , which is closely related seasonal freeze–thaw heat conduction advection layer. During initial ablation period, primarily recharged by SPG, resulting short‐tail Our findings provide valuable insights into runoff generation concentration regions have important implications resource management.

Fragmented surfaces and harsh environments have always been the main obstacles hindering observation works of glaciers in central Tibetan Plateau (TP). The advent Terrestrial Laser Scanner (TLS) technology offers a potential revolution this context. While TLS has effectively applied to smaller Alps Tianshan, study extends its use large topographically complex Ganglongjiama (GLJM) glacier Tanggula Mountains. Over 5-year period, TLS, with precision up 0.012 m, documented an accelerated melting trend, terminus retreating by 13.305 m total mass loss 2.580 water equivalent. research also underscores role supraglacial channels lakes intensifying surface front instability. Despite challenges data acquisition due occlusions logistical constraints at high altitudes, first survey TP provides invaluable insights into dynamics. Future could integrate Unmanned Aerial Vehicle-Structure-from-Motion (UAV-SfM) fusion achieve more comprehensive coverage improve temporal resolution observations for detailed analysis features.

Abstract. Our study explores the intricate relationships between new water (Fnew), young (Fyw), and topographic influences within small catchments, utilizing Height Above Nearest Drainage (HAND) as a key metric. Analysis revealed that seepage consistently contains higher fractions of than stream water, despite similar contributions from precipitation, highlighting differential hydrological responses. The relationship Fnew Fyw exhibited varying slopes for suggesting distinct sources behaviors, with reflecting “flashy” system indicating “damped” system. A nonlinear dynamic was observed HAND transit time measures, notable threshold at approximately 10 m HAND, beyond which contribution to streamflow declines, shift in pathways. This behavior emphasizes complex influence topography on movement age catchments. research bridges gaps our understanding catchment hydrology, offering insights into spatial temporal dynamics pivotal role landscape features shaping
