A wide and precise water-depth investigation was conducted in the discharge area of the modern Yellow River in 2007, and a more elaborate survey was done in the south area of Qingshuigou in 2009 by the Institute of Oceanology. Topographical and morphological features are studied from these precise data. Several large gullies lie across the front slope of the subaqueous delta at about 5m depth area. The 2009 data indicate that erosion is getting more and more serious. The erosion/deposition distribution features of the subaqueous delta are analyzed through comparison of the 2000, 2007 water-depth data with the four topographic profiles designed in modern and abandoned mouth area.
