英文摘要：

A flood monitoring system model of Yellow River with multi-spectral remote sensing images is proposed in this paper.This model is a combination of analysis and evaluation functions of automatic main-stream detection,river regime variation analysis,and floodplain detection.In this paper,firstly,the principles and algorithm of the main-stream detection,river regime variation and floodplain based on remote sensing images are described in detail.Then,experiments based on multi-spectral remote sensing images are carried out to verify the detection algorithms.Finally,the results are analyzed and system model is built.Experimental results indicate that the model presented in this paper has important practical value in flood monitoring of Yellow River.
