Dendrogeomorphology has been demonstrated to be a valuable tool for studying hydrogeomorphic processes in ungauged or poorly catchment. However, an appropriate knowledge of the response of trees to these processes is crucial for proper interpretation of dendrochronological signal. In this communication, we present results from the study of damages riparian trees (Alnus glutinosa, Fraxinus angustifolia and Salix atrocinerea) by floods from the Spanish Central System by mean of X-ray computed tomography (XRCT). Analyses are focused on macroscopical features as well as on the characterization of internal density variations using a novel geostatistical application. The objective is to understand the eco-physiological impact of floods in three common Mediterranean riparian trees species and, therefore to improve the tree sampling efficacy for futures dendrogeomorphological studies.
