Research On Early Warning And Release System Of Regional Debris Flow Disaster

The debris flow has become one of the main geological disasters that cause mass casualties.It has seriously threatened the safety of people's lives and property,and the governments departments have paid great attention to the debris disaster.But the cause mechanism of debris flow geological disaster is very complex,which involves many aspects such as geological structure,runoff,rainfall,human activity and other geological disasters,and because of many types of debris flow,the outburst is different.So far,human beings have not been able to master the mechanism.Based on the research results of domestic and foreign related fields,this paper has made a little beneficial attempt on the debris flow early warning and prediction research,and developed the early warning and forecasting system and information publishing system based on the debris flow early warning and forecasting business requirements.The main work contents are as follows:(1)According to the research objectives,we introduce and analyze the current debris flow prediction and prediction algorithm,and give the main technical solutions of this paper.(2)The early warning and prediction model of regional debris flow is studied,and the key debris flow gully early warning and regional debris flow early warning and prediction methods are analyzed in detail,and the related models and algorithms are realized.(3)Based on the technology of ArcEngine and ArcGIS Server,combined with the models and algorithms proposed in this paper,the debris flow early warning and forecasting system and information publishing system are realized,and the key technologies are expounded in detail.The test of historical data shows that the proposed algorithm is scientific and achieves the design goal of this paper.
