We show preliminary results of a VLA HI-imaging survey and deep NIR imaging of large volume regions in the Abell clusters A85/A496/A2670. We inspect both, the gas and stellar disks of the brightest galaxies (late-types in the case of HI) in order to disentangle between hydrodynamic and gravitational mechanisms driving the evolution of infalling galaxies to these clusters. Our NIR imaging is coming from telescopes going from the 2m (OAN-Mex), 3.6m CFH, up to 5m (Palomar) telescopes, devoted to search for asymmetries on the old stellar disks of individual galaxies. We look for correlations between global HI properties of these clusters and elements such as ICM drawn in X-ray, dynamical degree traced by internal substructures, and the large scale structure where these systems are embedded in. At the end, we use this approach to compare the observed properties of galaxies in these nearby clusters (z<0.1) with model predictions for galaxy evolution occurring between z=1 and z=0.
