Focusing on the project management of the Xin Wanfu River, this paper systematically analyzes its current situation and existing problems, and puts forward targeted innovative strategies. The navigation restoration project started in 2018 and the "14th Five-Year Plan" improvement project aim to increase the standards of flood control and waterlogging elimination. However, there are many challenges in river management. The planting mode in the embankment area and flood land needs to be optimized, and the problem of "four-aspect disorders" is prominent, which threatens flood discharge and aquatic ecological security. Therefore, it innovatively puts forward the "1 + 1 + 1 + 3" mode in four-level management and protection mechanism, promotes the "small fields merged into large fields", formulates assessment systems, expands funding channels and establishes a mass cooperation mechanism. It is expected to realize the early detection and handling of river problems and build a more perfect and efficient river management system.
