  We investigate the sensitivity of some of the proposed next-generation
neutrino experiments to a galactic supernova. In particular, we study how well
the supernova parameters (the average energies and luminosities) can be
separated from the unknown neutrino oscillation parameters ($\theta_{13}$ and
the neutrino mass hierarchy). Three types of experiments, all in the 100-kton
class, are compared. These are: a 540 kton water-Cherenkov detector, a 100 kton
liquid Argon detector and a 50 kton scintillator detector. We demonstrate that
practically all of these proposed detectors have the possibility to determine
the hierarchy of the neutrino masses if the angle $\theta_{13}$ is sufficiently
large ($\sin^2(\theta_{13}) > 10^{-4}$) and the hierarchy of the average
energies is larger than about 20%. They can at the same time determine some of
the supernova parameters well. The average energy of the $\nu_\mu$ and
$\nu_\tau$ species can be determined within 5% uncertainty in most of the
parameter space suggested by supernova simulations. The detection of several
separable channels measuring different combinations of charged current and
neutral current processes is crucial for determining the value of $\theta_{13}$
and the hierarchy. However, there are cases where a few of the SN parameters
can be determined rather well even if only the main charged current detection
channel is available.
