For researching the laws of flow path into sea movement in siltladen rivers, according to the measured topographic data since 1976 to 2015, it analyses the course of the flow path movement during in Qingshuigou path in Huanghe estuary. The results show that current flow paths deposits and extends controlled by runoffs and ocean hydrodynamics. The old flow paths are eroded and dominated by ocean power. The runoffs and sediment into sea reduce by 42% and 78% after 1996, respectively. As a result, the averaged deposition rate reduces by 81%. The avulsion rate of the flow path into sea is also decreased.
