Resumen
Las Angustias torrent is an ungauged stream located in the Caldera de Taburiente National Park (Canary Islands), where frequent and intense flood events occur (even causing fatalities, such as in November 2001). The aim of this research is to analyse the flood hazard in one of the most visited areas of this protected area. To carry out this objective, during two dendrogeomorphological campaigns, all pine trees located on the stream bed and banks showing external evidence of flash flood damage were sampled. In addition, a detailed topographical survey using GPS and total station allowed us to obtain the inputs for hydraulic modelling. In the preliminary results, two flood events have been identified (1967-1968 and 1999-2000), and evidence of other dates has been observed (1976, 1983, 1993 and 2001). Magnitude reconstruction of these events will improve flood hazard and risk analyses and will be useful for National Park managers.
