Abstract: I present a study of observational and physical properties for a large dataset of highly precise, well-sampled BVI light curves and spectra of type-II plateau supernovae. For this purpose, I calculate (1) a set of parameters that characterize the bolometric light curves, and (2) a grid of hydrodynamical models for a range of progenitor masses, radii, explosion energies, nickel masses, and mixing using a newly developed, one-dimensional, Lagrangian hydrodynamic code. I perform a comparison between models and data in a consistent way, and I study correlations between different observed and physical parameters.
