We know that the rainfall threshold of debris flow is different in different debris flow catchments. Then, What factors lead to different rainfall thresholds in different debris flow catchments, and which of these factors play a decisive role? Is there any method or model to establish the relationship between these factors and rainfall thresholds in different debris flow catchments?
There is a broad range of factors that affect rainfall thresholds, both meteorological and land surface methods. The intensity of rainfall, physical properties of soil, vegetation cover, geological properties of the land, etc.
Dear Yan Zhao, İf you have some data, you may make multi regression among these variables and make your own software (can be excel based).
