Résumé
In this paper is presented a study dealing with the debris flows that
reached the national road 7 in January 2005, in the km 1,118.5, Mendoza
province. The area is located in the Frontal Cordillera near the
limit of the Precordillera. A detailed geomorphologic map has been
realized for this study using a Quickbird satellite imagery of the
year 2006. Various calculations of volumes, velocities and peak discharges
have been performed with the field data and using a geographic information
system (GIS). The geomorphologic survey has permitted to propose
three propagation scenarios in case of a new event. These allowed
creating a map of debris flows susceptibility for the stretch of
the road that has been studied. Finally, it has been proposed protection
and mitigation measures, based on the results of the study, to protect
the road from a new event.
