We study the impact of local environment on the transformation of spiralgalaxies in three nearby ($z < 0.08$) Abell clusters: A85/A496/A2670. Thesesystems were observed in HI with the Very Large Array, covering a volumeextending beyond the virial radius and detecting 10, 58, 38 galaxies,respectively. High fractions (0.40--0.86) of bright spirals[log$(M_{*}/M_{\odot})=9-10$] are not detected in HI. We provide furtherevidence of environmental effects consisting in significant fractions(0.10--0.33) of abnormal objects and a number of red (passive) spirals,suggesting an ongoing process of quenching. Ram-pressure profiles, and thesample of the brightest spirals used as test particles for environmentaleffects, indicate that ram-pressure plays an important role in stripping andtransforming late-types. Phase-space diagrams and our search for substructureshelped to trace the dynamical stage of the three systems. This was used tocompare the global cluster effects $vs.$ pre-processing, finding that theformer is the dominating mechanism in the studied clusters. By contrasting theglobal distribution of HI normal $vs.$ HI disturbed spirals in the combinedthree clusters, we confirm the expected correlation of disturbed objectslocated, on average, at shorter projected radii. However, individual clustersdo not necessarily follow this trend and we show that A496 and A2670 present anatypical behavior. In general we provide conclusive evidence about thedependence of the transformation of infalling spirals on the ensemble ofcluster properties like mass, ICM density, dynamical stage and surroundinglarge-scale structure.
