Query: What can we learn on supernova neutrino spectra with water Cherenkov
  detectors?   We investigate the precision with which the supernova neutrino spectra can be
reconstructed in water Cherenkov detectors, in particular the large scale
Hyper-Kamiokande and Super-Kamiokande. To this aim, we consider quasi-thermal
neutrino spectra modified by the Mikheev-Smirnov-Wolfenstein effect for the
case of normal ordering. We perform three 9 degrees of freedom likelihood
analyses including first inverse-beta decay only, then the combination of
inverse beta decay and elastic scattering on electrons and finally a third
analysis that also includes neutral scattering neutrino-oxygen events. A tenth
parameter is added in the analyses to account for the theoretical uncertainty
on the neutral current neutrino-oxygen cross section. By assuming a 100\%
efficiency in Hyper-Kamiokande, we show that one can reconstruct the electron
antineutrino average energy and pinching parameter with an accuracy of
$\sim2\%$ and $\sim7\%$ percent respectively, while the antineutrino integrated
luminosity can be pinned down at $\sim3\%$ percent level. As for the muon and
tau neutrinos, the average energy and the integrated luminosity can be measured
with $\sim7\%$ precision. These results represent a significant improvement
with respect Super-Kamiokande, particularly for the pinching parameter defining
the electron antineutrino spectra. As for electron neutrinos, the determination
of the emission parameters requires the addition of supplementary detection
channels.
