To systematically evaluate the implementation effect of maintenance dredging in the upper Yangtze River waterway in 2018 and provide technical reference for future waterway maintenance projects，based on the systematic analysis of the water situation，we evaluate the dredging project from the dredging scheme design，construction timing，dynamic management of construction process，as well as sustainability of the channel. The results show that the selection of beach section and the design of dredging scheme basically adapt to the river evolution law. The time and frequency of dredging are basically reasonable，which reduce the contradiction with navigation to the greatest extent. However，since the maintenance dredging has not significantly changed the river flow characteristics and riverbed boundary，the sustainability of shallow channel in the natural reach is poor，so it is still necessary to strengthen observation or take other regulation measures.
