RESUMEN: Se realizó un primer estudio de susceptibilidad a los flujos de detritos a escala regional a lo largo de la Ruta Nacional N7 (Argentina), donde numerosas cuencas producen flujos de detritos afectando la ruta. Se utilizó un modelo de elevación digital con una resolución de 30 m y tres criterios para discriminar las áreas fuentes (pendiente, área de aporte y curvatura del terreno). El recorrido de los flujos de detritos se estimó con un modelo basado en SIG (Flow-R) utilizando algoritmos de probabilidad y de energía. Se eligieron dos de los mejores valores (µ = 0.02 and M/D = 180) para el coeficiente de fricción y el “mass-to-drag ratio” del modelo PCM, estos a su vez fueron validados con el modelo de fricción de Coulomb. Los resultados son coherentes y ayudan a definir las áreas que necesiten un estudio más detallado.
