Debris Flow Warning System Design by Diao Zhongba on the Basis of GIS

Article Preview

Abstract:

Aiming at guaranteeing the security of Zhong Ba village, reducing investment capital and preventing geological disasters, it is necessary to design debris flow alarming system in Diao Zhongba. Being a basic platform, geographic information system software MAPGIS is fully taken advantage for managing engineering geology information in Diao Zhongba. Then research on secondary development library based on MAPGIS is conducted for achieving debris flow alarming function. Detailed design of debris flow alarming system in Diao Zhongba district is made on systematic requirement analyses, systematic overall design, system environment selection, data base detailed design and module design on alarming function. The system designs 10 kinds of models in all which includes flood peak flow computation model of dam breaking and flood peak evolution process model of dam burst. The system can conduct an automate information process on debris flow with which serves as the references for debris flow alarming in Diao Zhongba district.
