According to remote sensing information from Landsat and NOAA images, besides the meteorological factor, the flooding and waterlogging of the Yellow River and the Huaihe River are mainly controlled by modern activity tectonic. There are some hidden dangers in the lower reaches of thr Yellow River for the current river course and the river banks lack of stability. The flood overflowing from the upper to middle reaches of the Huaihe River is difficult to drain off because this area located in a modern depression. This situation constitutes a threat to some extent to Beijing-Jiulong Railway and the people living in the lower reaches of those two rivers.
