  abstract = {{G}lacier-wide mass balances and runoffs are reconstructed over 1969-2016 for {C}hhota {S}higri {G}lacier catchment ({I}ndia) applying a glacio-hydrological model. {T}he model is forced using in-situ daily air-temperature and precipitation records from the meteorological stations at {B}huntar {O}bservatory (1092 m a.s.l.), glacier base camp (3850 m a.s.l.) and glacier side moraine (4863 m a.s.l.). {T}he modelled mean annual mass balance is -0.30 +/- 0.36m w.e.a(-1) (meter water equivalent per year), while the mean catchment-wide runoff is 1.56 +/- 0.23 m w.e.a(-1) over 1969-2016. {T}hree periods are distinguished in the reconstructed mass balance and runoff series. {P}eriods {I} (1969-1985) and {III} (2001-2016) show glacier mass wastage at rates of -0.36 and - 0.50 m w.e.a(-1), respectively, corresponding to catchment-wide runoffs of 1.51 and 1.65 m w.e.a(-1), respectively. {C}onversely, period {II} (1986-2000) exhibits steady-state conditions with average mass balances of -0.01 m w.e.a(-1), and corresponding runoff of 1.52m w.e.a(-1). {T}he reduced ice melt (0.20m w.e.a(-1)) over period {II}, in agreement with steady-state conditions, is compensated by the increased snow melt (1.03 m w.e.a(-1)), providing almost similar catchment-wide runoffs for period {I} and {II}. {T}he increased runoff after 2000 is mainly governed by increased ice melt (0.32m w.e.a(-1)) over period {III}. {S}now accumulation in winter and summer seasons together control the glacier-wide mass balances as well as catchment-wide runoffs. {S}now melt contributes the maximum to the total mean annual runoff with 63% share while glacier melt and rain contribute 17% and 20% respectively over the whole period.},
