Supplemental Materials for Hierarchical Multi-Scale Prediction of Slope-hazard Susceptibility Along Mountain Expressway Corridors

This supplemental material provides additional figures supporting the manuscript entitled "Hierarchical Multi-Scale Prediction of Slope-hazard Susceptibility Along Mountain Expressway Corridors: A Case Study of the Lianying Expressway in Northern Guangdong, China".The supplemental materials include:(1) spatial distribution and statistical characteristics of road-proximity constraint factors;(2) distribution characteristics of categorical engineering-geological factors at the 500 m evaluation scale;(3) distribution patterns of continuous and angular engineering-geological factors at the 500 m evaluation scale.These materials are provided to supplement the analyses presented in the main manuscript.
