Resumen:
 We present a detailed study of the kinematic and physical properties of the ionized gas in multipleknots of the blue compact dwarf galaxy Haro15.  Using echelle and long slit spectroscopy data, obtained with different instruments at Las Campanas Observatory,we study the internal kinematic and physical conditions (electron density and temperature), ionic and totalchemical abundances of several atoms, reddening and ionization structure. Applying direct and empirical methods for abundance determination, we perform a comparative analysis between these regions. On the other hand, our echelle spectra show complex kinematics in several conspicuous knots within the galaxy.To perform an in-depth 2D spectroscopic study we complete this work with high spatial and spectral resolution spectroscopy using the Integral Field Unit mode on the Gemini Multi-Object Spectrograph instrument at the Gemini South telescope. With these data we are able to resolve the complex kinematical structure within star forming knots in Haro15 galaxy.
