We present results of combined surveys of the HI (NRAO-VLA) and NIR (5m-Palomar and 3.6m CFHT) in several clusters of the nearby universe (z<0.1). By observing large volumes of these clusters we are able to explore different environments, from the low density outskirts until the very crowded clusters cores. Studying the ISM of spirals (seen in HI) and, on the other hand, the old stellar components of member galaxies (traced by the NIR), permits to determine the most likely physical mechanism driving the morphology transformation responsible of the density-morphology relation.
