Research Abstract

Conclusion : Possibly maximum travel distance of a debris flow is horizontal distance of 10 against altitude difference of 1 starting from the location of the slope failure where the debris flow is initiated from. We do not have to worry about the possible danger of a debris flow in case that there is no potentially collapsible slope wit
