GCL Model by the determination of the characteristics in the beginning zone of the debris flows using a GIS

Abstract

In recent years an increase in the prevalence of debris flows has been observed in various regions of the world. These events, which have caused a significant amount of damage to cities, infrastructure and ecosystems; emphasize the importance of developing early warning systems to alert residents of the danger in advance. A model to determine the probability of occurrence of a debris flow through the development of a geographic information system that combines a digital elevation model and a distributed hydrological model is described.
