N2 - We have developed a comprehensive Monte Carlo analysis in order to simulate the neutrino signal from a galactic supernova in a large water Cerenkov detector. This allows us to demonstrate that, by exploiting the various features of the signal in a way which is largely independent of the supernova model, assuming only that the late-time behaviour of the signal is flavor independent, a sensitivity to a tau-neutrino mass down to the cosmologically interesting range of ≈ 25 eV for a medium luminosity burst is possible. This is the case even though the tau signal involves ≈ 50 out of ≈ 10 000 total events in a detector of the size of that proposed for "Super Kamiokande". In addition, our results allow us to elucidate several aspects of a supernova neutrino signal in water detectors which had not been previously explored, including new results on the observability of the neutrinization burst.
