Abstract: It has been ten years since Yellow River changed its riverway from Diaokou Course to the other one ¨C Qingshuigou Course in 1996. At Q-8 surface, seabed landform has been remodeled largely as a result of seabed-clay which come from Yellow River silting and fusing continuously. By dint of the analyses of the softwares (for example AutoCad, Surfer, etc.), the range of clay fusing and the status of clay eroding-silting in different sections have been obtained.

Key words: seabed-clay, section, surfer, eroding-silting
