The modified theoretical model for debris flows predication with multiple rainfall characteristic parameters.

ABSTRACT: The debris flows are one of the most serious geological hazards frequently occurring in the arid and semi-arid regions of northwest China, effectively monitoring and warning against which is of crucial importance. Focusing on the most hazardous debris flow region of Altay, 22 rainfall events that triggered debris flows and 100 rainfall events that did not result in debris flows were systematically evaluated. The mathematical statistics were adopted to identify the characteristics of rainfall (i.e., rainfall intensity, duration, antecedent effectiveness, and direct rainfall amount before the triggering of debris flows). Subsequently, various machine learning methods were employed to determine the optimal impact weights of these rainfall characteristics. The comprehensive rainfall intensity
