Methods, apparatus and electronic equipment for dynamic simulation of melt-driven debris flows

Abstract

This invention belongs to the field of disaster prevention and control technology, and relates to a method, device, and electronic equipment for dynamic simulation of melt-driven debris flows. The method includes acquiring environmental monitoring parameters and topographic data, constructing a temperature-snowmelt model, and calculating the snowmelt rate; acquiring soil freeze-thaw parameters, constructing a water-temperature coupled soil infiltration model, and calculating the spatiotemporal distribution data of soil temperature, soil solid-liquid phase, and residual snowmelt water on the surface; and constructing a multiphase mass flow model to calculate the spatial distribution data of runoff / debris flow within the watershed over time. This invention couples the three stages of snowmelt, soil infiltration, and runoff / debris flow propagation, while simultaneously considering the influence of temperature changes, substrate material entrainment, and substrate material particle composition. It effectively describes the formation process of melt-driven debris flows, obtaining more accurate and refined debris flow dynamics results, and more accurately assessing the erosion rate of the substrate material.
