Abstract

Morphometric caracterization of Pudio River basin (El Aljarafe, Sevilla). Compared analysis during the last fifty years (1956-2006). We analyzed the main morphometric features of the basin and drainage network of Pudio river (El Aljarafe, Sevilla) for the years 1956 and 2006. We compare both situations and show the experienced trend in the basin in the last fifty years. A significant loss of torrencial capacity has been observed , with channel disappearance, more significant at the basin top, and in connection with the above, a decline in the ability of erosive channels.
