 Resumen:

 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.
