We study the ionised gas kinematics in the Halpha emission line with the scanning Fabry-Perot interferometer at the Russian 6-m telescope. We are searching for the regions with a high velocity dispersion and with significant velocity deviations from the tilted-ring model of pure circular rotation. Such features could indicate the infall of external gas or the feedback from the massive stars and supernovae in the star-forming regions. Using the additional spectral observations and the multiwavelength archival data we may distinguish between the different sources of accreted gas in the case of inflows and study the feedback process in the case of outflows.
