In the Dongjiang River Basin, there is a wide range of rivers, lakes and reservoirs. Traditional means played a great role in the management of the Dongjiang River Basin. In order to adapt to the river basin management in the new period, Dongjiang River Basin Administration of Guangdong Province has carried out three application research based on the application of remote sensing technology in river basin management. The results show that remote sensing technology get practical application for the management of Dongjiang river basin, such as remote sensing of water quality, Water quality parameter inversion, Monitoring of floating objects (e. g. water hyacinths), delimitation of reservoir works etc. It is proposed to use remote sensing technology in a wider range of basin management, and the monitoring accuracy of related parameters is further improved.
