Abstract: Nowadays,flood is one of the most serious natural disasters in the world.Its scientific and effective monitoring and assessment provided the foundation for the flood prevention and mitigation.The basic theory of the flood monitoring by satellite remote sensing was briefly introduced.The research progress on techniques of the flood water extraction,the calculation of the flooded area and the depth of the floodwater,and the impact assessment of flood disasters was summarized,based on satellite data,such as Landsat TM and ETM+,SPOT,EOS/MODIS and NOAA/AVHRR etc.It was concluded that the remote sensing technology for the floodwater extraction was matured.The calculation of flood area based on GIS was relatively matured.The floodwater depth was still difficult to obtain and the corresponding technology was needed to be improved further.The impact assessment technology was developing quickly,while the methods,models and the accuracy of the quantitative assessment were needed to be studied further.Based on those conclusions,the microwave remote sensing,artificial neural networks,GIS could be widely applied in the flood disaster satellite remote sensing monitoring,especially the remote sensing data could be extensively utilized in the assessment process.
