Abstract:There are many problems when using current methods to predict the loss caused by post-earthquake debris flow disasters: long time for prediction, large errors in the results, and low prediction efficiency and accuracy. In this paper, a coupling prediction method for post-earthquake debris flow disaster loss based on GIS technology was proposed. GIS technology was adopted to obtain the information about post-earthquake debris flow disasters. Based on the acquired information, a watershed calculation model, a solid mass calculation model, and a debris flow starting model were established to analyze the starting process of debris flow. Based on the property loss prediction model and personnel loss prediction model, a coupling prediction model of post-earthquake debris flow disaster loss was constructed. The experimental results show that the proposed method has high prediction efficiency and accuracy.
Keywords:GIS technology  debris flow disaster  loss forecast  predictive model
