Query: HI gas, environment, and SF-quenching in the Abell clusters
  A85/A496/A2670   We study complete sample of spiral galaxies brighter than M$_{\mathrm{B}}
\sim$-18.4 in three Abell clusters: A85 ($z=\,$0.055), A496 ($z=\,$0.033) and
A2670 ($z=\,$0.076). This work is based on a large volume limited, blind
Hi-survey (21cm, NRAO-VLA), on optical imaging (CFHT) and on the search for
dynamical substructures. Our goal is to explore the effects of local
environment on the HI gas properties and this, in turn, on the star formation
activity and quenching of individual galaxies. We report significant
differences among the HI properties of these clusters and we discuss the role
played by the large scale structure and by the dynamical evolution of each
cluster accounting for the observational evidence.
