  We study the neutral hydrogen distribution and kinematics in the Local Group
dwarf irregular galaxy IC 1613 and compare them with the ionized gas
distribution and stellar content of the galaxy. We discuss several mechanisms
which may be responsible for the origin of the observed complicated HI
morphology and compare parameters of the most prominent kpc-scale HI structure
with the multiple SNe scenario.
  The observations were performed with the Vary Large Array of NRAO with a
linear resolution ~23 pc at the adopted distance of 725 kpc and the spectral
channel width of 2.57 km/s. The numerical calculations have been provided with
our 2.5D Lagrangian scheme based on the thin layer approximation.
  We found that the ISM of the galaxy is highly inhomogeneous and identified a
number of intermediate-scale (200 pc - 300 pc in diameter) HI arcs and shells
having expansion velocities of 10 to 20 km/s. Besides these shells, several
giant holes and arc-shaped structures have been revealed, whose radii exceed
several hundred parsecs. We found that parameters of the most prominent (M_HI =
2.8 x 10^7 Msol) kpc-scale structure and the level of the detected star
formation activity are inconsistent with the multiple SNe hypothesis.
