Flood Disaster Monitoring and Evaluation System Based on GIS and Remote Sensing: Case Study in Hejiang River

Article Preview

Abstract:

Flood disaster occurs frequently in Hejiang watershed, Guangxi province which causes huge economic and social losses. Remote sensing technique (RS) has the advantage of quickness, economy, objectiveness and large observation area. As is known to all, geographic information system (GIS) is good at analyzing and dealing with spatial data. Based on GIS, RS and hydrological and hydraulic models, flood disaster evaluation system of Hejiang river is developed which realizes the seamless connection of GIS platform with Xinanjiang model and Muskingum model. GIS system combined with necessary information obtained from remote sensing images could extract useful thematic information of flood disaster, which is meaningful to flood control and disaster relief of local authorities.
