Abstract: According to analysis of estuary deposition and erosion recently, the estuary channel has been eroded, water lever of the same discharge decreased since water and silt regulation. But the erosion of the channel lower than Qing 6 section by the regulation is unobvious. There are also some problems such as silt transport power is insufficient, erosion and elongation rate is too fast, river position changes greatly. So, the authour put forward some recommendations such as enforcing river dredging, carrying out silt roiling together with water and silt regulation, perfect river training works as soon as possible etc..

Key words: water and silt regulation deposition elongation Yellow River mouth
