Abstract

In this paper, the average rate of the river Darro incision (Granada, Spain) is calculated over the historical period 1890-2010 in the urban section (Alhambra-Valparaiso sector). This has been used historical photographs that this river appears, from which it has been possible to determine the position of the channel at the time when the photographs were made. Comparison with the current scenarios has identified the height difference of the channel through absolute coordinates measures undertaken by theodolite. This methodology has allowed quantitatively estimate an index of mean vertical engagement of the river for the data collection time of 1,05 cm / year.
