  abstract = {{T}he deadliest outburst flood from an englacial cavity occurred on {G}lacier de {T}ete {R}ousse in the {M}ont {B}lanc area, {F}rench {A}lps, in 1892. {A} subglacial reservoir was discovered in the same glacier in 2010 and drained artificially in 2010, 2011 and 2012 to protect the 3000 inhabitants downstream. {T}he mechanism leading to the spontaneous refilling of the cavity following these pumping operations has been analyzed. {F}or this purpose, the subglacial water volume changes between 2010 and 2013 were reconstructed. {T}he size of the cavity following the pumping was found to have decreased from 53 500 m(3) in 2010 to 12 750 m(3) in 2013. {C}reep and the partial collapse of the cavity roof explain a large part of the volume loss. {A}nalysis of cavity filling showed a strong relationship between measured surface melting and the filling rate, with a time delay of 4-6 hours. {A} permanent input of 15 m(3) d(-1), not depending on surface melt, was also found. {T}he meltwater and rain from the surface is conveyed to bedrock through crevasses and probably through a permeable layer of rock debris at the glacier bed. {T}he drainage pathway permeability was estimated at 0.054 m s(-1) from water discharge measurements and dye-tracing experiments.},
