Progress, Challenge and Prospect for Remote Sensing Monitoring of Flood and Drought Disasters in China

The frequent floods and droughts in China have seriously affected the development of the national economy and people’s lives. Remote sensing can rapidly and extensively monitor, assess and warn the flood and drought disasters. This paper reviewed the progresses of Chinese flood and drought disaster monitoring by using remote sensing, described the development and innovation of models and methods in flood and drought disaster monitoring with remote sensing technology, discussed the challenges of remote sensing monitoring of flood and drought disasters, and finally, explored the development tendency of remote sensing monitoring of flood and drought disasters in the new era.
